RESUMO - No presente estudo pretende-se contribuir sobre a compreensão geológica da porção onshore Bacia Sedimentar do Espírito Santo, onde há poucos estudos publicados. Identificaram-se fácies sedimentares de maior ocorrência como fácies rudáceas, areníticas e lamíticas, com cores branca a cinza claro, formando depósitos tabulares com gradação normal e interacamadados. Estratificações acanaladas incipientes foram observadas, assim como feições de acresção lateral, escavação e preenchimento de canais. As fácies areníticas e rudáceas são mal selecionadas, matriz-suportadas, constituídas principalmente de quartzo, feldspato (alguns bem preservados) e argilominerais diagenéticos e, também fragmentos do embasamento, rochas sedimentares e uma possível contribuição de material vulcanossedimentar. Os lamitos são pouco espessos, tabulares e raramente bioturbados. Além dessas fácies, foi identificado um espesso depósito conglomerático de matriz areno-argilosa, possivelmente decorrente de um fluxo de alta densidade, já que contêm blocos dispersos de argilito na porção basal e, mais ao topo, seixos orientados e estratificação plano-paralela, indicando corrente unidirecional de alta velocidade. Faz contato erosivo na base com um arenito fino e bem selecionado, que está depositado próximo ao embasamento. Considerando as formas de ocorrência, estruturas e características faciológicas, sugere-se a evolução em ambiente fluvial entrelaçado, em condição de aporte/nível de base que permitiu a deposição próximo à área fonte. Palavras chaves: Fácies sedimentares. Porção onshore da Bacia Sedimentar do Espírito Santo. Formação Rio Doce. Formação Barreiras. ABSTRACT - In the present study, the aim is to contribute to the geological understanding of the onshore portion of the Espírito Santo Basin. The most common sedimentary facies were identified, such as rudaceous, arenitic, and lamitic facies, with colors ranging from white to light gray, forming tabular deposits with normal grading and interbedded layers. Incipient cross stratifications and lateral accretion, channel excavation, and filling features were observed. The arenitic and rudaceous facies are poorly sorted, matrix-supported, and consist mainly of quartz, feldspar (some well-preserved), diagenetic clay minerals, and fragments from the basement, sedimentary rocks, and possibly some contribution of volcanosedimentary material. The lamites are thin, tabular, and rarely bioturbated. Different of these facies, a thick conglomerate deposit with a sandy-clay matrix was identified, possibly resulting from a high-density flow, as it contains dispersed claystone blocks in the basal portion and upward, oriented pebbles and planar-parallel stratification, indicating a high-velocity unidirectional current. It has an erosive contact at the base with a fine and well-sorted sandstone deposited near the basement. Considering the occurrence forms, structures, and facies characteristics, an evolution in a braided fluvial environment is suggested, in a condition of sediment supply/base level that allowed continental deposition. Keywords: Sedimentary facies. Onshore portion of the Espírito Santo Sedimentary Basin. Rio Doce Formation. Barreiras Formation.

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.

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.

Os fósseis foram coletados nos anos de 1997 e 1998, na área rural do Município de Monte Alto - SP, e hoje compõem parte do acervo do Museu de Paleontologia de Monte Alto. Os dentes isolados de tal afloramento são o principal material de estudo deste trabalho, que, acrescidos a outros dados obtidos através da análise das feições bioestratinômicas e geológicas da região, permitiram tecer uma interpretação paleoecológica para o Afloramento Santa Irene. Foram analisados vinte e seis exemplares de dentes de arcossauros carnívoros, sendo dezoito deles enquadrados como Theropoda e oito como elementos dentários pertencentes aos Crocodyliformes. Os dentes de Theropoda se distinguem daqueles de Crocodyliformes por serem os primeiros mais achatados lateralmente, além de apresentarem serrilhas. Foi possível constatar que quatorze dos dezoito exemplares classificados dentro da Subordem Theropoda apresentam características pertencentes à Ceratosauria, família Abelisauridae, e Maniraptora, família Dromaeosauridae. A coleção de dentes de Crocodyliformes coletados no afloramento Santa Irene consiste de oito exemplares em geral cônicos, com estriamento ao longo da carena, podendo ou não apresentar bordos serrilhados e seção basal arredondada, sendo possível classificá-los dentro da família Trematochampsidae. Os fósseis articulados e com pouco desgaste do Aeolosaurus indicam um soterramento parcial logo após a morte ou ainda na fase de destruição de seus elementos não esqueléticos. A observação do afloramento e do seu entorno permitiu deduzir que a região apresentava rios, possivelmente, entrelaçados com deposição sazonal de sedimentos e períodos de estabilidade com a formação de solos incipientes. Durante os períodos interdeposicionais e de formação do solo, nota-se a ocorrência da precipitação de minerais, dando origem à formação de calcretes, resultado de períodos secos marcantes. O afloramento Santa Irene representa a deposição de rios que formavam barras arenosas, nas quais diversos grupos de animais buscavam água e alimento. Conclui-se que estes animais habitavam ou transitavam por aquele ambiente, pois não há sinais de que os fósseis tenham sido transportados até o local no qual foram coletados, mas sim que a carcaça do Aeolosaurus serviu de alimentação para outros animais no local de sua morte. Desta forma, o material analisado permitiu a reconstituição de um retrato impar de um ecossistema a muito extinto Abstract: The Santa Irene outcrop has been considered one of the most significant of the Bauru Basin, in the Adamantina formation, because of abundance and good preservation of associated fossils found there, as isolated teeth of carnivorous archosaurs associated with fossils of a herbivorous sauropod dinosaur. The fossils were found in 1997 and 1998, in rural areas of the city of Monte Alto - SP, and today compose the collection of the Museum of Paleontology of Monte Alto. The isolated teeth from this outcrop is the main material of this paper, which, together with other data obtained by analysis of biostratonomic and geological features of the region, allowed to make a paleoecological interpretation of the outcrop Santa Irene. Twenty-six copies of teeth of carnivorous archosaurs were analyzed, eighteen of them being classified as Theropodomorpho and eight teeth as belonging to Crocodyliformes. The teeth of Theropodomorpho can be distinguished from those to be the first Crocodyliformes as they are more flattened laterally, besides having serrations. It was found that fourteen of the eighteen specimens classified within the suborder Theropoda fit the characteristics belonging to Ceratosauria, family Abelisauridae and Maniraptora, family Dromaeosauridae. The collection of Crocodyliformes teeth collected from the outcrop Santa Irene consists of eight copies generally conical, with streaking along the keel, presenting or not serrated edges and rounded basal section, being possible to classify them within the family Trematochampsidae. The articulated and with little wear fossils of Aeolosaurus indicate a burial soon after death or during the destruction of its non-skeletal elements. The observation of the outcrop and its surroundings allow deducing that the region had braided rivers with seasonal sediment deposition and periods of stability with the formation of incipient soils. During no deposicional intervals periods and soil formation, can be noted the occurrence of precipitation of minerals, giving rise to the formation of calcrete, result of striking dry periods. The outcrop of St. Irene was formed by rivers that formed sand bars, in which various groups of animals tried to find food and water. It can be deduced that these animals lived or transited through that environment, because there is no evidence that the fossils were transported to the location in which they were collected, but that the Aeolosaurus remains served as food for other animals at his death location. Thus, the analyzed material allowed the reconstitution of an unique portrait of an ecosystem to long extinct Mestrado Geologia e Recursos Naturais Mestre em Geociências

The overarching goal of this work was to trace the origins of organic matter as a possible biosignature for early life on Earth. This work documented the petrological, structural, isotopic, elemental and molecular properties of organic matter, in a suite of sediments ranging from the Eoarchean to the Phanerozoic. Particular attention was paid to iron formations which form a major part of the Precambrian sedimentological record. Optical and micro-Raman spectroscopy were used to document the petrological occurrences of organic matter and its associated diagenetic features. Focused ion beam and transmission electron microscopy were used to detail the nanoscale structures of the organic matter. Mass spectroscopic techniques were utilised to measure the isotopic, elemental and molecular properties of organic matter and its petrographically associated carbonate. The timing and possible mechanisms of organic matter formation were investigated and evaluated, against the observed attributes of the organic matter. This work has documented organic matter forming key mineral associations with apatite and carbonate, which point to the diagenetic recycling of biogenic carbon. The diagenetic cycling of organic matter is proposed, to fuel the formation of granules during organic matter, iron and sulphur cycling. This cycling is hypothesised to lead to heterogeneity in organic matter structure and preservation in sediments. Additionally, this work has demonstrated that fluid deposited graphite in metamorphosed sediments may represent redistributed, syngenetic organic matter, shedding light on the controversial origins of graphite biosignatures in Earths oldest rocks. Finally, a detailed study of microfossil structures and their associations with organic matter and biominerals in iron formations was conducted to provide evidence for the preservation of Proterozoic microfossils, and the earliest signs of life on Earth.

Theoretical models for the evolution of extensional sedimentary basins make a number of simple, testable predictions for subsidence behaviour. These are that active extension (the syn-rift) will generally be accompanied by rapid subsidence on the downthrown side of normal faults. Once faulting has ceased (the post-rift) the entire basin is predicted to subside at an exponentially decreasing rate, driven by the cooling and thickening of the lithosphere. The aim of this thesis is to determine the significance of second-order departures from this predicted subsidence. Three periods of North Sea subsidence appear to violate these simple predictions: anomalously slow Late Jurassic/Early Cretaceous subsidence, which marks the syn-rift/post-rift transition, and two periods of accelerated post-rift subsidence during the Early Paleogene and Plio-Quaternary. Subsidence data from over 300 boreholes from several basins with different rifting histories on the Northwest European continental plate have been analysed to determine the spatial and temporal distribution of these and other second-order subsidence anomalies. Uncertainties and errors in the observed subsidence calculations cannot explain the anomalous behaviour recognised. The periods of apparently anomalous subsidence are, instead, shown to be the result of geological or tectonic processes that modified either the subsidence history or record of subsidence of the basins studied. Apparent slow Late Jurassic/Early Cretaceous subsidence in the North Sea was the result of well siting and sediment starvation. Analysis of wells from the downthrown side of normal faults in several basins reveals an excellent correlation between rapid subsidence (often >1000m in 10My) and active extension (as documented from other sources of geological information). This was obscured by intense sediment starvation (sedimentation rates <20m/My) in the Central North Sea during Late Jurassic times which generated the apparent subsidence anomaly. Sedimentation rate maps reveal an expansion of the area of sediment starvation during late Jurassic times and into the Early Cretaceous. Cretaceous to Recent sedimentation patterns were then dominated by the interplay between the location and erosion history of extra-basinal sediment source areas and the remnant underfilled Jurassic rift topography.

Submarine canyons are one of the most dramatic morphological features on continental margins and enable sediment transport from the shelf to the deep sea; however, the exact processes operating within submarine canyons are poorly understood. Much of our understanding of the dynamics of sediment-laden flows in submarine canyons results from making inferences from the deposits that they leave behind in the geological record. This thesis aimed to better understand what deposits can reveal about flow processes and ultimately to test the validity of this approach for reconstructing flow dynamics. This aim was achieved by 1) analysing seafloor bedforms, 2) the detailed lithological and ichnological analysis of submarine canyon deposits, and 3) utilising turbidity current monitoring data. Construction and analysis of a global database of seafloor bedforms suggests that bedforms across all scales and a wide variety of settings can be generated by supercritical flows. The most complete dataset of monitored turbidity currents in a submarine canyon was combined with precisely located vibracores collected in Monterey Canyon. The combination of these datasets demonstrates that deposits can be used to accurately infer flow properties, and the data were further used to develop a new three-part model for turbidity current behaviour: 1) flows begin as thin, high-concentration highly energetic flows; 2) the flows become more dilute with an expanding head; and 3) the flow rapidly thickens along its length. This new model of turbidity current behaviour, along with understanding the frequency of these events, explains the distribution of benthic communities in Monterey Canyon based on the biogenic sedimentary structures identified within the sedimentary cores.

Sedimentary organic matter contains many compounds that have no obvious biogenic precursors, so their formation and occurrence are of geochemical interest. The first part of this thesis (chapters 2-5) discusses the results obtained from studying hydrocarbon racemates. Some of the compounds identified are also suggested as intermediates in the formation of alkylnaphthalenes identified in chapters 6-7. The second part of this thesis (chapters 6-11) covers the identification of a range of alkylnaphthalenes and alkylphenanthrenes in sedimentary organic matter. Possible pathways for the formation of these hydrocarbons are outlined and their application as probes into the processes of petroleum formation are described.In chapter 2 the use of permethylated cyclodextrin capillary gas chromatography columns to separate hydrocarbon racemates are reported. Chapter 3 reports the synthesis of 1,2,2,5-tetramethyltetralin and 1,2,2,5,6-pentamethyltetralin and identifies them as racemates in crude oil. They are proposed as intermediates in the formation of sedimentary alkylnaphthalenes (identified in chapters 6 and 7).The identification of isodihydro-ar-curcumene in sedimentary organic matter is described in chapters 4 and 5. It co-occurs in crude oil with dihydro-ar-curcumene and is suggested to originate from this compound via a sedimentary rearrangement process. Chiral GC-MS techniques have been used to show the presence of both enantiomers of these compounds in crude oils. The elution order of the enantiomers has been established using reference compounds of known configuration. The effects of maturity and biodegradation on dihydro-ar-curcumene and isodihydro-ar-curcumene enantiomers is reported. Optically pure dihydro-ar-curcumene from natural products undergoes rapid racemisation in the subsurface, yielding a racemic mixture before the onset of significant oil formation. 1,2-Alkyl shifts on the aromatic ring also begin at an early stage to yield isodihydro-ar-curcumene and these processes continue with increasing maturity. Laboratory experiments using proton and clay catalysts (Lewis acid catalyst) show that the alkyl shift reaction is catalysed by both proton and Lewis acids, and racemisation is only catalysed by Lewis acids. A moderately biodegraded crude oil has been shown to be depleted in the R enantiomer of dihydro-ar-curcumene and an extensively degraded oil has dihydro-ar-curcumene depleted relative to isodihydro-ar-curcumene.The identification of a number alkylnaphthalenes and their possible origins in sedimentary organic matter is described in chapters 6 and 7. In chapter 6 a previously unreported tetramethylnaphthalene (TeMN) was identified in petroleum. This compound is structurally similar to bicyclic compounds of microbial origin and these are suggested as a likely source, via a tetralin intermediate identified in chapter 3. In chapter 7 isomeric pentamethylnaphthalenes previously unreported in sedimentary organic matter are reported. These isomeric pentamethylnaphthalenes (PMNs) were identified in a number of crude oils and sediments, ranging in age from Proterozoic to Tertiary. 1,2,3,5,6-PMN is suggested to form predominantly from the aromatisation of drimanoid precursors via 1,2,2,5,6-pentamethyltetralin identified in chapter 3. In laboratory experiments, the other pentamethylnaphthalenes were generated from 1,2,3,5,6-PMN in proportions that reflect the relative stability of the isomers. By analogy, the other PMNs in sediments are suggested to arise via acid catalysed isomerisation or transalkylation processes. A maturity parameter was developed based on laboratory experiments in conjunction with observed distributions of pentamethylnaphthalenes.The formation of alkylnaphthalenes and alkylphenanthrenes through a methylation process is discussed in chapters 8-10. Several crude oils and shales which contain anomalously high concentrations of 1,6-dimethylnaphthalene, 1,2,5-trimethylnaphthalene, 1,2,7-trimethylnaphthalene, 1,2,3,5-tetramethylnaphthalene, 1,2,3,5,6-pentamethylnaphthalene, 2-methyl-6-isopropyl-1(4-methylpentyl)naphthalene, phenanthrene, 1-methylphenanthrene, 1,7-dimethylphenanthrene and retene have been shown to contain relatively high concentrations of their corresponding methylated counterparts. In laboratory experiments carried out under mild conditions, each of the alkylnaphthalenes and alkylphenanthrenes have been shown to be methylated in specific positions when heated with a methyl donor in the presence of a clay catalyst. These observations have been interpreted as evidence for a sedimentary methylation process.The effect of biodegradation on alkylnaphthalenes and alkylphenanthrenes formed from sedimentary methylation is described in chapter 11. Land-plant-derived aromatic hydrocarbons with a range of susceptibilities to reservoir biodegradation have been identified in crude oils. These compounds are the result of reactions of natural products involving aromatisation, rearrangement and methylation in the sediments (chapters 9 and 10). They are therefore suggested as markers for land-plants in severely biodegraded oils in which most of the other biologically derived compounds cannot be recognised. The order of biodegradability of these compounds has been assessed relative to their non-methylated counterparts namely 6-isopropyl-2-methyl-1-(4-methylpentyl)naphthalene and retene. The order of degradation of the four compounds is : retene < 9-methylretene ~ 6-isopropyl-2-methyl-1-(4-methylpentyl)naphthalene > 6-isopropyl-2,4-dimethyl-1-(4-methylpentyl)naphthalene. These results have been used to assess that a crude oil is a mixture of severely biodegraded and less biodegraded crude oil.

Accumulating in deposits of various sedimentary formations argillaceous minerals, taking into account their alterations and new formations at different stages of sedimentary process in each of them, are characterized by specific chemical-mineralogical and morphologic-genetic features. Allothigenous argillaceous ones have background meaning in sediments of sedimentary formations. Argillaceous minerals and their associations in terrigenous, terrigene-carbonate, carbonate, volcanogenous, and halogenic formations were characterized. In specific details argillaceous minerals of early stages of sedimental- and diagenesis (partially katagenesis) were Сharacterized, to which most of ancient (Upper Paleozoic and Mesozoic) diamondiferous placers are usually confined, by availability in which of kimberlite indicator minerals prospecting of primary deposits of diamonds with the help of heavy concentrate-mineralogical method are performed. The importance for solving of forecast-prospecting tasks of investigating material composition of volcanogegic formation and specific features of its material distribution during formation of different in age collectors of diamonds on specific diamondiferous regions of the Siberian platform is shown.
