Abstract:

Based on the observation and description of single well and outcrops and the analysis of reservoir compositions, petrology, clastic structure and sedimentary structure,this paper determines the sedimentaty facies characteristics of Tanzhuang formation. The types of sedimentary facies in late Triassic epoch are delta front,shallow lake and semi-deep lake. The delta front develops subaqueous distributary channel, mouth bar and distal bar. Lacustrine facies develops shallow lake mud, shallow lake sand bar, turbidite sand and semi-deep lake mud.The reservoir rock formations in this area are lithic sandstone,feldspathic lithic sandstone with high content of feldspar and debris.The sedimentary structures include ripple, scour surface and cross-bedding are identified.

Abstract:

Os arenitos de praia, ou beachrocks, são sedimentos que sofreram um processo de litificação e são encontrados paralelamente à linha de costa na zona intermaré, apresentando uma forma alongada, estreita e cimentados por carbonato de cálcio. O processo de diagênese consiste na formação da rocha sedimentar propriamente dita a partir da compactação, dissolução, cimentação e recristalização. O estudo da formação e diagênese do arenito de praia são relevantes pois possibilita o entendimento de como as rochas sedimentares detríticas são geradas, além de reconhecer como a variação do nível do mar se comportou durante o Holoceno, permitindo a gênese destas feições que se constituem em relevantes elementos de resguardo das linhas de costas em ambientes majoritariamente tropicais. FORMATION AND DIAGENÈSE IN BEACHROCKS:A Conceptual Review ABSTRACTThe beach sandstones, or beachrocks, are sediments that underwent a lithification process and are found parallel to the coastline in the intertidal zone, presenting an elongated, narrow shape and cemented by calcium carbonate. The process of diagenesis consists on the formation of the sedimentary rock itself, following deposition, compaction, dissolution, cementation and recrystallization. The study of the formation and diagenesis of beach sandstone is relevant since it permits the understanding of how clastic sedimentary rocks are formed, besides with recognizing how sea level variation behaved during the Holocene, thus allowing the genesis of these features that constitute relevant elements of shelter along coastlines in most tropical environments. Keywords: Beachrocks, sedimentary rock, cementation.

Abstract:

Igneous intrusions in sedimentary basins are commonly related with mineralogical association changes in host-rock. At Sapopema region (Paraná State, southern Brazil), an extensive diabase sill (associated to Serra Geral Formation) was emplaced in pelitic-carbonate succession during post-Triassic. The sedimentary host-rock association includes mostly shale, siltstone and carbonate of the Permian Irati Formation. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) data revealed that heat transfer was not enough to cause modifications in mineral assemblage of the Taquaral Member (quartz + albite + muscovite + illite + kaolinite + chlorite). However, mineralogical content from Assistência Member presented changes probably caused by the intrusion of diabase sill (talc + pyrophyllite + calcite). Talc and calcite were formed due to the reaction between dolomite and quartz, while pyrophyllite was the product of reaction between kaolinite and quartz. EFEITOS DA INTRUSÃO IGNEA NA COMPOSIÇÃO MINERALÓGICA DA FORMAÇÃO IRATI, BACIA DO PARANÁ, SAPOPEMA (PR), SUL DO BRASIL ResumoAs intrusões ígneas em bacias sedimentares dão origem em geral a alterações mineralógicas da rocha hospedeira. Na região de Sapopema (Estado do Paraná, sul do Brasil), uma extensa soleira de diabásio (associada à Formação Serra Geral) pós-Triássica, foi intrudida numa sucessão sedimentar constituída por pelitos e carbonatos. A associação de rochas sedimentares hospedeiras, era principalmente constituída por folhelho, siltito e carbonato da Formação Irati, do Permiano. Dados de difração de raios X (DRX), microscopia eletrônica de varredura (MEV) e espectroscopia de energia dispersiva (EDS) revelaram que a transferência de calor não foi suficiente para causar modificações na composição mineralógica do membro Taquaral (quartzo + albita + moscovita + ilita + caulinita + clorita). No entanto, o conteúdo mineralógico do Membro Assistência apresentou alterações, provavelmente causadas pela intrusão do diabásio (talco + pirofilita + calcita). O talco e a calcita foram formados devido à reação entre dolomita e quartzo, enquanto a pirofilita foi o produto da reação entre a caulinita e o quartzo. Palavras-chave: Bacia Sedimentar.

Este trabalho teve como objetivo a caracterização dos aspectos sedimentares da planície costeira da praia do Iguape através da análise de dados estatísticos, levando em consideração, também os impactos socioambientais decorrentes do uso e ocupação. A área de estudo se encontra em Aquiraz, Região Metropolitana de Fortaleza (RMF). Historicamente o município começou a se evidenciar após a integração do município na RMF em 1973, onde passou a se destacar devido ao turismo. A faixa de praia do município possui aproximadamente 29 km de extensão, onde se encontram as praias do Batoque, Barro Preto, Iguape, Presídio, Prainha, Japão e Porto das Dunas. Para o alcance desses objetivos, a metodologia empregada foi dividida em levantamentos bibliográficos e documentais, a coleta de dados e a elaboração de material cartográfico. Diante disto obtivemos os resultados através da frequência simples, medidas de curtose, assimetria, média e mediana. Foi verificada a predominância de areia média e areia fina em todas as amostras, já os valores de assimetria e curtose apresentaram a predominância de aproximadamente simétrica com 67% e a predominância mesocúrtica (62%) e leptocúrtica (33%). Verificou-se que a dinâmica sedimentar foi caracterizada pela grande mobilidade sedimentar, mais perceptível na faixa de praia.Palavras-chave: Litoral de Aquiraz; Praia do Iguape; Dinâmica sedimentar. ABSTRACTThis study aimed to characterize the sedimentological settings of the coastal plain of Iguape beach through the statistical data, also taking into account the socioenvironmental impacts resulting from use and occupation. The study area is in Aquiraz, Região Metropolitana de Fortaleza (RMF). Historically the city began to show itself after the integration of the municipality in the RMF in 1973, where it began to stand out due to tourism. The Aquiraz is approximately 29 km long, where are the beaches of Batoque, Barro Preto, Iguape, Presidio, Prainha, Japan and Porto das Dunas. To achieve these objectives, the methodology employed was divided into bibliographic and documentary surveys, data collection and the preparation of cartographic material. We obtained the results through simple frequency, measures of kurtosis, skewness, mean and median. The predominance of medium sand and fine sand was verified in all samples, while the values of skewness and kurtosis were predominantly symmetrical with 67% and the predominance of mesocurtic (62%) and leptocurtic (33%). It was verified that the sedimentary dynamics was characterized by the great sedimentary mobility, mainly in the beach system.Keywords: Aquiraz Coastline; Iguape Beach; Sedimentary dynamics.

Abstract:

Through the studying of heavy mineral assemblages and ZTR index variation features, this paper analyses the provenances and sedimentary systems of Saertu reservoir in Cretaceous of Jiangqiao-Pingyang area, western slope zone in northern of Songliao basin. It is concluded that there are three major sedimentary systems in the Saertu reservoir depositional period, named the Nehe-Yian sedimentary system in Northeast, Yingtai sedimentary system in Southwest, Qiqihaer sedimentary system in Northwest. The intensity and influence scope of the sedimentary systems in sedimentary period of SaII+III, SaIand Sa 0 reservoir changed. During the sedimentary period of SaII+III reservoir, research area is mainly controlled by the Qiqihaer and Yingtai sedimentary systems, the control action of Nehe-Yian sedimentary system in the research area is faint. During the sedimentary period of SaIreservoir, Nehe-Yian sedimentary system control the sedimentation of mainly region in research area, the control range of Qiqihaer sedimentary system has shrunk to the West of Jiangqiao area, the Yingtai sedimentary system dropped out of the research area. During the sedimentary period of Sa 0 reservoir, the control action of each sedimentary system basically inherited the distribution pattern of the sedimentary period of SaIreservoir, but the source supply capacity weakened further.

Abstract:

The Ebinur Lake Basin is a typical terrestrial sedimentary Basin in Northwest China that has developed a piedmont distributive fluvial system (DFS) sedimentary environment, lake sedimentary environment, and desert sedimentary environment. The Ebinur Lake receives the sediments carried by the rivers in the basin and is the regional sedimentary center. In this study, a division scheme of modern sedimentary system tracts in the Ebinur Lake Basin was proposed. According to the landform, sedimentary environment, structure, and sedimentary system types, the Ebinur Lake Basin was divided into five system tracts. The area with high altitude and steep gradients mainly develops the rapid sedimentary system DFS, and the area with the lowest altitude in the region develops the lake sedimentary system. The main action area of climate drought and wind field is the dune sedimentary area. The wind field under the influence of hydrological climate and geomorphology has an important influence on the distribution of the sedimentary system tract. The structure determines the development of different types of sedimentary systems by controlling the topographic fluctuation and sedimentary space. Hydroclimate and geomorphology affect the development of sedimentary systems by controlling the sediment source rate in the sedimentary area. Based on the analysis of the characteristics and distribution of the modern sedimentary system in the Ebinur Lake Basin, a method for determining the level of the sedimentary system of the Ebinur Lake was established together with a plane model of the sedimentary system of the Ebinur Lake, which provides a reference for the study of the sedimentary system of continental basins.

Abstract:

In this paper, 6 kinds of reservoir sedimentary microfacies distribution model-conceptual model have been established by the use of reservoir sedimentology theory and methods, namely, large sandy braided river sand body sedimentary model, large meandering river sand body sedimentary model, low bending-straight distributary channel sedimentary model, crevasse splay (crevasse river) sedimentary model, heart beach sedimentary model, flood plain and distributary plain sheet sand body sedimentary model. On this basis, the sedimentary facies figures of four sedimentary units have been painted, putting forward the evolution law of sedimentary environment in the research zone, thus providing basic data for the facies control modeling.

ABSTRACT. This paper presents the results of satellite-derived gravimetry for Abrolhos Continental Shelf and the adjacent areas, States of Esp´ırito Santo and Bahia,Brazil, and discusses tectonic genesis of the sedimentary basins. The free-air and Bouguer anomalies on the continental shelf show a gradual increase from coast tocontinental shelf break. The total difference of 135 mGal indicates crust thinning of 4.5 km. The Bouguer anomaly increases beyond the shelf break and continues upto the abyssal plane. The total difference of 260 mGal suggests crustal thinning of 9.0 km. The studied area has two types of passive continental margin: 1) ES-typewith high continental slope, low and narrow continental rise, and high free-air and Bouguer anomalies; 2) SP-type with low continental slope, high and wide continentalrise, and low gravity anomalies. There are three types of sedimentary basins with different geologic structure and tectonic genesis: 1) Basins on the continental shelf,CSH-type; 2) Basin on the continental rise, CRS-type; 3) Continental rift basin, CRF-type. The CSH-type, as Esp´ırito Santo basin, has coherent free-air and Bougueranomalies 40 to 50 mGal lower than the adjacent areas. The sedimentary deposits are 2.0 to 2.5 km thick. The basement depression is sustained by mechanical strengthwithout isostatic compensation. The normal faults of basin border are limited within upper crust. The CRS-type, as Pedro Can´ario basin, has low local residual Bougueranomaly with difference of 40 mGal. The sedimentary deposits are more than 2.7 km thick. The continental side basin border is under isostatic compensation due todeep normal fault between continental slope and continental rise. The oceanic side border is sustained by mechanical strength of the basement. The CRF-type, BesnardPassage, is a continental rift basin originated from mantle pull-apart tectonism. The rift bottom is under complete isostatic compensation. The normal faults of the grabenborder continue to the mantle. The Moho depth along the rift is at least 6.5 km shallower than the adjacent areas.Keywords: satellite-derived gravimetry, Abrolhos Continental Shelf, sedimentary basin, crustal thinning, isostatic compensation. RESUMO. Este artigo apresenta os resultados da gravimetria por satélite para a Plataforma Continental de Abrolhos e as áreas adjacentes, ES-BA, e discute as gêneses tectônicas das bacias sedimentares. As anomalias ar-livre e Bouguer na plataforma continental mostram um aumento gradativo a partir da costa até a quebra da plataforma continental. A diferença total de 135mGal indica afinamento da crosta continental de 4,5 km. A anomalia Bouguer se apresenta além da quebra da plataformae continua até o assoalho abissal. A diferença total de 260 mGal sugere afinamento crustal de 9,0 km. Na área estudada, observam-se dois tipos de margem continental passiva: 1) Tipo ES com talude continental alto, elevação continental baixa e curta e anomalias ar-livre e Bouguer altos; 2) Tipo SP com talude continental baixo, elevação continental alta e extensa e anomalias gravimétricas baixas. Existem três tipos de bacias sedimentares com estrutura geológica e gênesis tectônicas diferentes: 1) Bacias na plataforma continental, Tipo CSH; 2) Bacias na elevação continental, Tipo CRS; 3) Bacia de rifte continental, Tipo CRF. O Tipo CSH, como a bacia do Espírito Santo, possui anomalias ar-livre e Bouguer coerentes 40 a 50 mGal mais baixas do que as áreas adjacentes. Os depósitos sedimentares são de 2,0 a 2,5 km de espessura. A depressão do embasamento é sustentada pela rigidez mecânica sem compensação isostática. As falhas normais das bordas de bacias são limitadas dentro da crosta superior. O Tipo CRS, como a bacia Pedro Canário, tem baixa anomalia Bouguer local com diferença de 40 mGal. Os depósitos sedimentares têm mais de 2,7 km de espessura. A borda da bacia do lado continental está sob compensação isostática devido à falha normal profunda entre talude continental e elevação continental. Aborda do lado oceânico é sustentada pela rigidez mecânica do embasamento. O Tipo CRF, Passagem Besnard, é uma bacia do rifte continental originada do tectonis mode distensão do manto. O fundo da bacia está sob compensação isostática completa. As falhas normais da borda do graben continuam até o manto. A profundidade da Moho ao longo do rifte é pelo menos 6,5 km mais rasa do que as áreas adjacentes.Palavras-chave: gravimetria por satélite, Plataforma Continental de Abrolhos, bacia sedimentar, afinamento crustal, compensação isostática.

Abstract:

AbstractThe great historian V. O. Kliuchevskii found the key to Russian society in the relative simplicity of its social forms in comparison with Western Europe. But in writing his magisterial Course in Russian History he revealed a degree of complexity that belied his disarming formula. The apparent contradiction stems from the standard of comparison. There were elements of complexity in Russian society that had no counterparts in the experience of the West. Moreover, the definition of society in nineteenth-century social history may have been too confining. If we make the effort to explore the unique features of Russian history and at the same time expand the boundaries of social history, we may arrive at a more comprehensive picture of Russia's social structure on the eve of revolution.

Abstract:

Sediments are crucial to the understanding of environmental processes and conditions in a variety of systems. The study of sediments often focuses on quantity, but should involve more emphasis on the quality of the organic component, by utilising commonplace techniques employed by other disciplines. We provide a classification scheme that will allow those interested in organic matter quality to decide on appropriate techniques to apply, and discuss a variety of applications of the investigation of organic matter quality in diverse areas of Physical Geography. Firstly, this paper conceptualises organic matter quality by examining how different groups identify with this term, providing a classification scheme that may assist individuals in their exploration of organic matter character. Secondly, it identifies key areas of investigation linked to Physical Geography where research into organic matter quality may provide a necessary or useful component. Finally, it explains and evaluates crucial techniques for characterising organic matter quality.

Abstract:

Sedimentary microfacies refer to the smallest unit with unique rock structure, structure, thickness, rhythm, and other sedimentary characteristics and certain plane configuration rules in the subfacies zone. Sedimentary microfacies research is the most basic sedimentary unit formed in the same or basically the same sedimentary background. Sedimentary microfacies marks are the key to the division of sedimentary microfacies. If we cannot find effective marks, we cannot correctly divide sedimentary microfacies. These marks are mainly obtained from detailed observation of cores. On the premise of fully understanding the regional tectonic background of the study area, the sedimentary facies and sedimentary subfacies types within the oilfield control range are determined. In this study, the single-well facies and profile facies are deeply analyzed by observing and describing the cores of Chang 2 reservoir group in Huangjialing, north-central Ordos Basin, and comprehensively utilizing the data of coring, logging, and core analysis and testing. The basic sedimentary characteristics, types of sedimentary facies and microfacies, and plane distribution of sedimentary facies in this area are systematically studied. The results show that there are mainly three microfacies: underwater distributary channel, natural dike, and distributary bay. Among them, the microfacies of the underwater natural dike are relatively undeveloped, mainly the microfacies of underwater distributary channel and underwater distributary bay. These studies have important practical significance for the later exploration of oil and gas in Ordos Basin.

Abstract:

Sedimentary facies is the summation of all primary sedimentary features in a sedimentary unit, which is the product of sedimentation in a specific environment. It emphasizes the material performance of sediment formation conditions, including mineralogy, petrology, paleontology, geochemistry and geophysics. Therefore, it has unique sedimentary features in this environment. In this paper, the types and units of sedimentary facies which can reflect the basic characteristics and geometry of sedimentary system are established, and based on the comprehensive analysis of rock types, lithological assemblages, sedimentary structures, palaeontological assemblages and section structures, the sedimentary facies types of Xujiahe formation of Upper Triassic in the study area mainly include semi-arid flooded basin facies, delta facies, beach bar-lagoon system and lake facies, among which delta facies and beach bar-lagoon system are the main sedimentary facies types. Because sedimentary facies is the historical product of basin formation, evolution and extinction, it can not only reflect the formation conditions, temporal and spatial distribution and evolution law of related strata and rock types, but also be the basis for analyzing the nature and structural background of sedimentary basin. At the same time, the analysis of sedimentary facies is of great significance for understanding and analyzing the evolution history of basin and guiding the exploration and development of related oil and gas resources.

Abstract:

This article is dedicated to the role of L.V. Pustovalov in creating the theoretical foundations of sedimentary research in Russia, including determination and substantiation of the most important regularities governing sedimentary processes and their stages. The constituting stages of sedimentary processes, such as weathering, transport, and deposition, were identified and described. These stages lead to the differentiation of sedimentary material and the formation of sedimentary rocks of different composition and structure. The concepts of the stages of diagenesis and epigenesist (catagenesis) were formulated. For the first time, specific features of sedimentary process evolution were outlined, including sedimentation conditions and formation of individual sedimentary minerals and rocks.

Abstract:

The Uruguayan continental margin was generated following the fragmentation of the Gondwana supercontinent and the subsequent opening of South Atlantic Ocean. It constitutes an extensive sedimentation area in which three sedimentary basins can be found: the Punta del Este Basin, the southernmost portion of the Pelotas Basin, and the poorly defined Oriental del Plata Basin. The aim of this work was the identification and characterization of the different seismic units (seismic facies, systems tracts, depositional sequences) for the sedimentary interval assigned to the Eocene in the Uruguayan continental margin. Sequence stratigraphy was used as a basin analysis method for this purpose, using a database that consisted of approximately 10,000 kilometers of 2D seismic sections, acquired in exploratory surveys in 2007 and 2008. The workflow included the recognition of stacking patterns and/or stratal terminations, the definition of genetically significant stratigraphic surfaces and, based on these, the identification of systems tracts and depositional sequences. Three depositional sequences were identified in the studied sedimentary interval. The basal sequence is composed of four depositional systems tracts, including falling stage, normal regression (lowstand and highstand) and transgressive deposits. The intermediate sequence only preserves lowstand normal regression deposits. The third sequence is composed by three depositional systems tracts, including lowstand, transgressive and falling stage deposits. ResumoA margem continental uruguaia foi gerada após a fragmentação do supercontinente Gondwana e a subsequente abertura do Oceano Atlântico Sul. Constitui uma extensa área de sedimentação em três bacias sedimentares: a bacia de Punta del Este, a porção mais ao sul da Bacia de Pelotas e a Bacia Oriental del Plata, pouco definida. O objetivo deste trabalho foi a identificação e caracterização das diferentes unidades sísmicas (fácies sísmicas, tratos de sistemas, seqüências deposicionais) para o intervalo sedimentar atribuído ao Eoceno na margem continental uruguaia. Com este objetivo, utilizou-se a estratigrafia de seqüencias como método de análise de bacias, tendo-se utilizado um banco de dados constituído por aproximadamente 10.000 km de seções sísmicas 2D, adquiridas em pesquisas exploratórias em 2007 e 2008. O trabalho incluiu o reconhecimento de padrões de empilhamento e/ou terminações estratais, a definição de superfícies estratigráficas geneticamente significativas, tendo-se efetuado com base nelas, a identificação de tratos de sistemas e seqüências deposicionais. Três seqüências deposicionais foram identificadas no intervalo sedimentar estudado. A seqüência basal é composta por quatro tratos de sistemas deposicionais, incluindo a fase de abaixamento do nível do mar, a regressão normal e depósitos transgressivos. A sequência intermediária apenas preserva os depósitos de regressão normais de nível de mar baixo. A terceira seqüência é composta por três tratos de sistemas deposicionais, incluindo depósitos de nível de mar baixo, transgressivos e de abaixamento do nível do mar.

Abstract:

Field investigations in 2013–2014 on acid soils and in 2016–2017 on sedimentary soils showed that populations of two lymnaeids had decreased in number in central France since 1998. As several heat waves occurred in this region in 2018, 2019 and 2020, it was useful to check whether this decline had further increased in recent years. Surveys in 56 farms in the north-west and west of the Haute Vienne department (acid soils) and 37 farms in the south of Indre (sedimentary soils) were therefore carried out in 2020 and 2021 and the results obtained were compared with those recorded by our team in the same farms in 2013–2014 and 2016–2017. On acid soils, the overall number of populations decreased by 34.7% for Galba truncatula (out of 813 populations in 2013–2014) and 22% for Omphiscola glabra (out of 550), while it decreased by 25% for G. truncatula (out of 361 in 2016–2017) and 15.2% for O. glabra (out of 205) on sedimentary soils. Similarly, the overall density of overwintering snails significantly decreased by 80.7% for G. truncatula and 70.2% for O. glabra on acid soils, while it significantly decreased by 64.1% and 38.3%, respectively, on sedimentarym soils. In both cases, these decreases were more marked on acid soils than on sedimentary soils. In contrast, the habitats of G. truncatula and most of those colonized by O. glabra showed no significant variation in their area between the two periods of study. The decline in the number of these lymnaeid populations, observed since 1998, is still continuing today in central France and may be due in part to heatwave episodes s that occurred in 2018, 2019 and 2020 in this region.

Abstract:

The lacustrine fine-grained sedimentary rocks in the upper interval of the fourth member of the Eocene Shahejie Formation (Es4s) in the Dongying Depression are important shale oil exploration targets in Bohai Bay Basin. They are widely distributed and rich in organic matter. In this study, samples were observed under the optical microscope and FESEM, combined with geochemical test and physical property analysis to study the sedimentary characteristics and reservoir characteristics of them. Nine lithofacies are recognized based on the mineral composition, the content of organic matter and the beddings. The middle-high organic laminated calcareous fine-grained sedimentary rocks (LF1) and the middle-high organic laminated mixed fine-grained sedimentary rocks (LF2) resulted from seasonal sediment variations and settled by suspension in the deep lake. The middle-high organic flaggy mixed fine-grained sedimentary rocks (LF3), the middle-high organic flaggy calcareous fine-grained sedimentary rocks (LF4), the middle-high organic massive calcareous fine-grained sedimentary rocks (LF5) and the middle organic massive mixed fine-grained sedimentary rocks (LF6) were formed by redeposition. The low organic massive argillaceous fine-grained sedimentary rocks (LF7), the low organic massive felsic fine-grained sedimentary rocks (LF8) and the low organic massive mixed fine-grained sedimentary rocks (LF9) are affected by the terrigenous input events. The pore structures vary in different beddings which are influenced by the kinds and arrangement of minerals and particles. In the laminated lithofacies, the ink-bottle-shaped pores are dominant. In the flaggy and massive lithofacies, the ink-bottle-shaped pores and the slit-shaped pores coexist. LF1 and LF2 are the best target for shale oil exploration and the LF3, LF4, LF5 and LF6 are the second. The deposition processes control the lithofacies and reservoir characteristics of the fined-grained sedimentary rocks.

Abstract:

Taking the VII oil group of N21 reservoir in Gasikule Oilfield as an example, the sedimentary time unit was divided into the barrier layer, interbed, and sand bed by analyzing the sedimentary system and sand body development model in this paper. The single sand body was analyzed for the sand bed time unit. The residual muddy intercalation period division theory was proposed for the first time to divide the sedimentary periods of the sedimentary time unit of the sand bed. Finally, a new “sandwich” layer point coincidence modeling technology was proposed to characterize the sedimentary time units of a barrier layer accurately and interbed and finely describe the sedimentary time unit of the multiperiod sand bed.

Abstract:

Sedimentary facies type of the Shanxi Formation in northeastern Ordos Basin is an ongoing debate. Based on field measurements, sample collection and identification, and laboratory analysis, we systematically evaluated the sedimentary characteristics of the sandstone bodies of Shanxi Formation of Chengjiazhuang section in Liulin. Analysis included identifying sample composition, grain size, texture, sedimentary structure and spatial distribution. We came to the conclusion that the sedimentary environment of Shanxi Formation is deltaic. This deltaic environment included deltaic front and deltaic plain. It can be further divided into five sedimentary microfacies: subfluvial distributary channel, subfluvial distributary interchannel, distributary channel, levee, and peat bog. And lastly, the evolution of sedimentary environment of Shanxi Formation is discussed.

Abstract:

Sedimentation in the Archean Abitibi greenstone belt occurred during four depositional episodes: (i) sedimentary cycle 1, 2730–2720 Ma; (ii) sedimentary cycle 2, 2715–2705 Ma; (iii) sedimentary cycle 3, 2700–2687 Ma; and (iv) sedimentary cycle 4, 2685–2675 Ma. Records of the first two sedimentary cycles are preserved in basins within the northern volcanic zone, whereas basins formed during the latter two sedimentary cycles are located within the southern volcanic zone of the Abitibi belt. Sedimentary cycles 1 and 3 represent deep-water facies, as indicated by turbidites, resedimented conglomerates, pelagic sediments, and ubiquitous iron-formations; subaerial deposits have not been identified. In contrast, sedimentary cycles 2 and 4 show a prevalence of fluvial to shallow-water marine and (or) lacustrine deposits. Tectono-magmatic influence on sedimentation during cycles 2 and 4 is documented by (i) the presence of numerous unconformities underlain by plutonic and volcanic rocks; (ii) locally voluminous shoshonitic and calc-alkaline volcanic rocks; (iii) abundance of plutonic detritus; (iv) rapid vertical and lateral facies changes; and (v) repetition of successions of large-scale (50–250 m thick) alluvial and shallow-water deposits. Sedimentary cycle 1 represents incipient arc basins dominated by volcaniclastic debris, whereas cycle 2 reflects unroofing of arc volcanoes down to the plutonic roots. The sedimentary basins of cycle 3 have been tentatively interpreted as basins connecting arc terranes, within which small extensional cycle 4 basins of the successor or pull-apart type developed. The sedimentary facies associations, the tectono-magmatic influence on sedimentation, the chronological basin evolution, and overall southward younging of the basins invite comparison with modern island arcs formed by plate-tectonic processes.

Abstract:

Ediacaran fossils are sometimes reconstructed as colorful organisms of clear azure seas like tropical lagoons, or as ghostlike forms in deep, dark oceans. Alternatively, they can be envisaged as sessile organisms in frigid soils, to judge from associated Ediacaran periglacial paleosols and tillites. Additional evidence of cool Ediacaran paleoclimate now comes from reinterpretation of two supposed trace fossils: (1) grooves radiating from Ediacaran fossils interpreted as radular feeding traces (“Kimberichnus”) of supposed molluscs (Kimberella), and (2) chains of fossil impressions interpreted as feeding traces (“Epibaion”) of supposed worms or placozoans (Yorgia, Dickinsonia). The grooves are not curved with rounded ends like radular scratches, but with sharp or crudely bifid tips like frost flowers and frost needles extruded from plant debris. Fossil impressions in chains are not sequential feeding stations, but in polygonal arrays, like vagrant lichens and mosses displaced by wind gusts and periglacial frost boils. Thus, neither the taphomorph “Epibaion”, nor the ice crystal pseudomorphs “Kimberichnus” are valid ichnogenera. These newly recognized frost boils, needle ice, frost feathers, frost hair and frost shawls are additions to isotopic and glendonite evidence that the Ediacaran was another period in Earth history when even low paleolatitudes were cool.
