Abstract:

We develop a methodology for systematic inversion of quantitative stratigraphic models. Quantitative stratigraphic modeling predicts stratigraphy using numerical simulations of geologic processes. Stratigraphic inversion methodically searches the parameter space in order to detect models which best represent the observed stratigraphy. Model parameters include sea-level change, tectonic subsidence, sediment input rate, and transport coefficients. We successfully performed a fully automated process based stratigraphic inversion of a geologically complex synthetic model. Several one and two parameter inversions were used to investigate the coupling of process parameters. Source location and transport coefficient below base level indicated significant coupling, while the rest of the parameters showed only minimal coupling. The influence of different observable data on the inversion was also tested. The inversion results using misfit based on sparse, but time dependent sample points proved to be better than the misfit based on the final stratigraphy only, even when sampled densely. We tested several inversion schemes on the topography dataset obtained from the eXperimental EarthScape facility simulation. The clustering of model parameters in most of the inversion experiments showed the likelihood of obtaining a reasonable number of compatible models. We also observed the need for several different diffusion-coefficient parameterizations to emulate different erosional and depositional processes. The excellent result of the piecewise inversion, which used different parameterizations for different time intervals, demonstrate the need for development or incorporation of time-variant parameterizations of the diffusion coefficients. We also present new methods for applying boundary condition on simulation of diffusion processes using the finite-difference method. It is based on the straightforward idea that solutions at the boundaries are smooth. The new scheme achieves high accuracy when the initial conditions are non vanishing at the boundaries, a case which is poorly handled by previous methods. Along with the ease in implementation, the new method does not require any additional computation or memory.

A Bacia de Jacuípe é considerada uma bacia de nova fronteira localizada no Nordeste Brasileiro, na margem passiva leste, e estritamente offshore. Acredita-se que ela tenha um grande potencial para jazidas de hidrocarbonetos. Entretanto, há uma grande carência em estudos integrados que auxiliem no seu entendimento. O presente trabalho visa compreender a história evolutiva da bacia através da interpretação de sequências de segunda e terceira ordens em dados de sísmica de reflexão. A partir da interpretação de 40 perfis sísmicos 2D e do único poço perfurado, que encontra-se na região de plataforma, os autores puderam caracterizar importantes eventos dentro da bacia. Dentro da supersequência rifte foram reconhecidas quatro sequências deposicionais nomeadas Rift 1, Rift 2, Rift 3 e Rift 4, limitadas por três limites de sequência. Os riftes 1 e 2 têm deposições isoladas ao longo da bacia e as falhas sintéticas e antitéticas destas fases começam um processo de conexão. O Rift 3 tem a maior representatividade na bacia e seus depósitos cobrem a maior parte dela. O Rift 4 representa o fim da subsidência mecânica com menores expressões nos falhamentos e experimentou um soerguimento, o qual levou a atual plataforma continental a ficar exposta durante eventos subsequentes. A supersequência Drift foi subdividida em dois estágios drifte. Uma vez que a bacia sofreu um soerguimento ao final do seu rifteamento, o primeiro estágio do drifte tem o preenchimento sedimentar confinado ao talude e ao sopé continental. Enquanto que no segundo estágio do drifte a sedimentação ultrapassa a falha de borda e seus depósitos se sobrepõem à supersequência rifte na plataforma. Um mapa estrutural de falhas foi construído para a porção sul da Bacia de Jacuípe destacando os principais controles do falhamento, a linha de charneira da bacia, principais depocentros, o Alto Externo de Jacuípe e um alto vulcânico. O limite geográfico a sul com a Bacia de Camamu foi definido em uma zona complexa de falhas de transferência e de alívio, caracterizando assim, um limite geológico. Adaptações foram sugeridas para uma nova carta cronoestratigráfica para a porção sul da Bacia de Jacuípe.
ABSTRACT Jacuípe Basin is considered a new frontier basin in the northeastern Brazilian passive margin. It is believed it has a great potential for hydrocarbon plays and leads. However, it lacks in integrated studies for its understanding. The present paper aims to comprehend the evolutionary history of such basin through seismic reflection analysis of second and third orders sequences. With the interpretation of several 2-D seismic profiles and a well drilled on the platform the authors were able to distinguish important events within the basin. Within the rift supersequence it was recognized four sequences named as Rift 1, Rift 2, Rift 3 and Rift 4, limited by three sequence boundaries. Rifts 1 and 2 have scattered depositions and the synthetic and antithetic faults start a linkage process. Rift 3 has a wide spread representation throughout the basin covering most part of it. Rift 4 makes up the termination of mechanical subsidence with minor expression in faulting and has experienced an uplift whose led the currently continental shelf to be exposed most part of subsequent events. Drift supersequence was split in two drifting stages. Inasmuch as basin has undergone an uplift, the first drift stage has sedimentation confined to slope and rise regions. Whereas in the second drift stage sedimentation surpasses the border fault and its successions overlie directly rift supersequence in platform. A structural faulting map was built for southern Jacuípe Basin depicting main faulting controls and trends, basin hinge line, main depocenters, the Jacuípe External High and a volcanic plug. The geographic southern boundary with Camamu Basin was set up at a complex zone of transfer and release faults, making up a geologic limit. Adaptations were suggested for a new chronostratigraphic chart for southern Jacuípe Basin.

Abstract:

Ce travail pionnier porte sur l'étude de l'architecture stratigraphique du Bassin de la Cuanza à partir d'une approche conjuguée multi-échelle croisant la géomorphologie, l'interprétation sismique et la sédimentologie de faciès de l'intervalle Oligocène à Actuel. L'objectif est de préciser l'âge, le partitionnement de faciès, les milieux de dépôts de la zone littorale dans le but de dater et de caractériser les mouvements verticaux en relation avec le fluage du sel (tectonique gravitaire) et le soulèvement général de la marge en lien avec la déformation de la lithosphère. L'analyse détaillée des affleurements de la zone côtière permet de manière complémentaire de préciser les conditions de drainage de la paléo-Cuanza avec la mise en évidence d'un prisme deltaïque de type patte d'oiseau au Pliocène qui prograde sur un système éolien côtier. Par ailleurs, plus vers l'intérieur du bassin, à hauteur de BomJesus, une zone de haut-fond conduit à la mise en place d'un Gilbert delta alimenté par une possible proto-Cuanza, en marge de la plate-forme mixte du Miocène inférieur. Plus au large de cette plate-forme, dans le secteur de Cabo do São Braz à Barra do Cuanza, l'analyse détaillée de l'architecture stratigraphique sur les falaises permet de caractériser d'un point de vue faciès et processus de dépôt une succession de systèmes de chenaux-levées en compensation montrant localement des processus d'injection sableuse précoce en lien avec l'instabilité des bordures du chenal. Ces systèmes Oligocène à Pliocène sont étroitement contrôlés par la croissance des diapirs (Cabo Ledo) et alimentés à la fois par les apports fluviatiles, le démantèlement des plis diapiriques et des apports de la plate-forme mixte. A Sangano, les marges des chenaux turbiditiques contiennent des sables bioclastiques à bioturbations de type skolithos et Ophiomorpha qui indiquent l'instabilité gravitaire de la plate-forme qui borde les gouttières subsidentes, avec un potentiel de recolonisation du fond sableux par les faunes "turbiportées". En remontant vers le Nord on passe progressivement à des faciès de pente soulignés par des niveaux de black-shales qui marquent la fenêtre de productivité planctonique. Ces faciès sont surmontés par des marnes à intervalles de tempestites caractéristiques de l'offshore transition. Enfin, au Sud de Miradouro da Lua, on a pu mettre en évidence dans le Miocène supérieur des faciès contouritiques qui remontent la pente suivant une succession de cannelures d'érosion. Ces faciès sont tronqués par des dépôts sableux bioturbés typiques d'un environnement de shoreface. Depuis Cabo de Sao Braz jusqu'à Luanda on observe donc une succession à la fois temporelle et paléo-environnementale qui conforte le modèle de soulèvement différentiel/basculement de la série vers le Nord. Du Sud vers le Nord, on observe ainsi une évolution depuis des dépôts turbiditiquesinterdiapiriques oligocènes à miocènes inférieur dans le secteur de Cabo do São Braz/Cabo Ledo jusqu'à des faciès deltaïques de la paléo-Cuanza Pliocène et fluviatiles de braid-delta Pléistocène à hauteur de Miradouro da Lua
This pioneering work, focuses on the study of the stratigraphic architecture of the Cuanza Basin, from a combined multi-scale approach crossing the geomorphology, seismic interpretation and sedimentologicalfacies from Oligocene interval to Present. The objective is to identify the age, the partitioning of facies, the environments of deposition of the coastal zone in order to date and characterize the vertical movements in relation to the salt creep (gravitational tectonic) and the general uplift of the margin related to the deformation of the lithosphere. Detailed analysis of the outcrops of the coastal zone allowed in a complementary manner specify the conditions of drainage of the paleo-Cuanza putting thus in evidence the identification of a deltaic prism type bird's foot in Pliocene which prograde on a coastal aeolian system. In addition, over to the basin, up to Bom Jesus, a shoal area led to the establishment of a Gilbert delta powered by a possible proto-Cuanza, in conjunction with the mixed platform of lower Miocene. Most off the shelf, in the area of Cabo de Sao Braz to Barra do Cuanza, a detailed analysis of the stratigraphic architecture of the cliffs allowed characterize in a viewpoint facies and depositional processes in a succession of channel-levee systems in compensation, showing locally early sandy injection processes related to the instability of the channel borders. These systems Oligocene to Pliocene are tightly controlled by the growth of diapirs (Cabo Ledo) and and sometimes they are fed by fluvial deposits, dismantling folds diapirs and contributions from mixed platform. In Sangano the turbidite channel banks contain the bioclastic sands with bioturbations type Skolithos and Ophiomorpha which indicate gravitational instability of the shelf that edge the subsidence incisions with a potential for colonization of the sandy bottom by Fauns "turbiportées". Going up to the north we pass gradually to slope facies highlighted by levels of black-shale that marks the window of planktonic productivity. These facies are overlain by marl with intervals of tempestites, characteristics of the offshore transition. Finally, to the South of Miradouro da Lua, we were able to put in evidence in upper Miocene contouritesfacies that climbs the slope following a series of grooves erosion. These facies are truncated by sandy deposits bioturbed typical of shoreface. From Cabo de Sao Braz until Luanda, sometimes is possible to obsreve a temporal and paleoenvironmental succession which reinforces the model of differential uplift or tilting of the series toward to the North. From South to the North, is observed an evolution of interdipiricturbiditic deposits of Oligocene to lower Miocene in the area of Cabo do Sao Braz / Cabo Ledo to deltaic facies of the paleo-Cuanza - Pliocene fluvial braid-delta of Pleistocene in Miradouro da Lua

Abstract:

The principal objective of archaeology is to reconstruct in all possible ways the life of a community at a specific physical location throughout a specific time period. Distinctly separate layers of soil provide evidence for a specific time period. Discovered artefacts are most frequently used to date the layer. An artefact taken out of context is virtually worthless; hence the correct registration of the layer in which they were uncovered is of great importance. The most popular way to record temporal relationships between stratigraphic layers is through the use of the 2D Harris Matrix method. Without accurate 3D spatial recording of the layers, it is difficult if not impossible, to form new stratigraphic correspondences or correlations. New techniques for archaeological recording, reconstruction, visualisation and interpretation in 3D space are described in these works and as a result software has been developed. Within the developed software system, legacy stratigraphy data, reconstructed from archaeological notebooks can be integrated with contemporary photogrammetric models and theodolite point data representations to provide as comprehensive a reconstruction as possible. The new methods developed from this research have the capability to illustrate the progression of the excavation over time. This is made possible after the entry of only two or more strata. Sophisticated, yet easy-to-use tools allow the navigation of the entire site in 3D. Through the use of an animation-bar it is possible to replay through time both the excavation period and the occupation period, that is to say the various time periods in antiquity when human beings occupied these locations. The lack of complete and consistent recording of the soil layers was an issue that proved to be an obstacle for complete reconstruction during the development of these methods. A lack of worldwide archaeological consensus on the methods of stratigraphic recording inhibited development of a universal scientific tool. As a result, new recording methods are suggested to allow more scientific stratigraphic reconstruction.

Abstract:

This work focuses on the Late Pleistocene-Holocene transition in the southern Po Basin. Five areas were investigated, with the aim of unraveling the role of different allogenic factors (climate, eustacy, sediment supply) on stratigraphic architecture in the last 45 ky. The study starts from the distal portion of the basin (the coastal plain deposits) and then moves towards increasingly internal areas: the alluvial sector characterized by the Po channel belt deposits, and the mud-prone interfluvial succession between the Apenninic margin and the Po channel belt. In the coastal sector, high-resolution facies analysis, along with a well-constrained chronostratigraphic framework, led to the accurate paleoenvironmental reconstruction of the last 45 ky BP depositional history along the 93 km-long transect. It is also provided a sequence stratigraphic interpretation for the whole sedimentary succession. In the Po channel belt sector, based on 28 radiocarbon dates, facies interpretation from high-quality core descriptions and freshly-drilled continuous cores, the contrasting stratigraphic architecture of Late Pleistocene and Holocene deposits was highlighted. Changes in lithofacies and channel stacking patterns reveal the vertical superposition of amalgamated fluvial-channel sands (Late Pleistocene) and mud-dominated deposits (Holocene), with isolated fluvial-channel bodies. We also attempted to establish the link between facies architecture, sea-level fluctuations and climate changes. The 3rd study area (interfuvial succession) was selected to test a new method for paleosol identification, on the basis of geotechnical properties generated from pocket penetrometer values. Through the reconstruction of the Biferno coastal deposits (4th study area, located ca. 300 km south of the Po Plain) we had the opportunity to document two coeval (Late Pleistocene - Holocene) coastal sedimentary successions, diverging in terms of shelf gradient and proximity to the LGM-lowstand Po Delta. The 5th study area, broadly coincides with Ferrara, was selected to show how high-resolution stratigraphic studies can be used for aquifer protection.

Abstract:

This work focuses on the Late Pleistocene-Holocene transition in the southern Po Basin. Five areas were investigated, with the aim of unraveling the role of different allogenic factors (climate, eustacy, sediment supply) on stratigraphic architecture in the last 45 ky. The study starts from the distal portion of the basin (the coastal plain deposits) and then moves towards increasingly internal areas: the alluvial sector characterized by the Po channel belt deposits, and the mud-prone interfluvial succession between the Apenninic margin and the Po channel belt. In the coastal sector, high-resolution facies analysis, along with a well-constrained chronostratigraphic framework, led to the accurate paleoenvironmental reconstruction of the last 45 ky BP depositional history along the 93 km-long transect. It is also provided a sequence stratigraphic interpretation for the whole sedimentary succession. In the Po channel belt sector, based on 28 radiocarbon dates, facies interpretation from high-quality core descriptions and freshly-drilled continuous cores, the contrasting stratigraphic architecture of Late Pleistocene and Holocene deposits was highlighted. Changes in lithofacies and channel stacking patterns reveal the vertical superposition of amalgamated fluvial-channel sands (Late Pleistocene) and mud-dominated deposits (Holocene), with isolated fluvial-channel bodies. We also attempted to establish the link between facies architecture, sea-level fluctuations and climate changes. The 3rd study area (interfuvial succession) was selected to test a new method for paleosol identification, on the basis of geotechnical properties generated from pocket penetrometer values. Through the reconstruction of the Biferno coastal deposits (4th study area, located ca. 300 km south of the Po Plain) we had the opportunity to document two coeval (Late Pleistocene - Holocene) coastal sedimentary successions, diverging in terms of shelf gradient and proximity to the LGM-lowstand Po Delta. The 5th study area, broadly coincides with Ferrara, was selected to show how high-resolution stratigraphic studies can be used for aquifer protection.

Abstract:

In this research project the author introduces the use of geometrical modelling techniques alongside geostatistical methods to model a stratigraphic orebody and to present a graphics display system developed as a fIrst step towards a general integrated system for computer aided design and planning in mining. Geometrical modelling techniques and geostatistical methods are combined to carry out the process of modelling a stratigraphic orebody. From a mining point of view, there are two main features of interest in a stratigraphic ore-body: a-The modelling of the geometry of the orebody. b- The modelling (estimation) of the physical properties (grades, etc ... ) of the orebody. The first feature is the subject of this research project. Modelling methods and techniques developed elsewhere and for different applications, such as Computer Aided Design, have been applied successfully to model the geometry of stratigraphic orebodies. The modelling process consists of the applications of surface modelling techniques to represent the hangingwall and the footwall of the stratigraphic orebody and thereby to produce the space where the physical properties are geostatistically to be estimated. The graphics display system is presented to highlight the use of computer graphics techniques to communicate graphically all sorts of information concerning the modelling of stratigraphic orebodies and also to display the end product of the modelling process, such as cross-sections, plane-sections, wireframe and solid models of the orebody. The graphics system itself is part of a computer based system for mine design and planning similar to computer aided design systems used mainly in the manufacturing industry. The presentation of the research project in this thesis started by the review of the literature of some existing ore reserves estimation methods in the mineral industry, particularly geostatistical methods. Then an overview and the scope of this research project have been given. The second chapter describes the type of data which could be encountered while building a geometrical model of a stratigraphic orebody and a description of data from a nickel vein deposit used as a case study for this research project. The accumulations have been estimated geostatistically subject to geometrical control. The geometrical control concept and surface modelling techniques are presented in chapter three together with the numerical application of modelling a nickel vein deposit using two different surface modelling techniques. Chapter four describes the graphics display system developed to display several geometric features of stratigraphic orebodies in two and three dimensions. The summary of this research project and some concluding remarks are given in chapter five.

Mestrado em Engenharia Geológica
The Tertiary deposits of the Sado Basin (in southwestern Portugal) were deposited in a typical continental basin, composed by 4 main lithostratigraphic units. During the Palaeogene, the Sado Basin was a closed basin in which the mineralogy of the primary facies underwent significant changes that resulted in the extensive occurrence of palygorskite. The Palaeogene fill of the Sado basin is composed by reddish coarse detrital sediments (conglomerates, arkosic sandstones, clays and marly carbonates). 28 samples representative of the most exposed outcrops of these units were collected and analysed by XRD, XRF and SEM-EDS for their mineralogical and chemical characterization. SEMEDS was used to compute the crystallochemical formulas for the identified clay minerals. Clay minerals associations were used as lithostratigraphical markers as well as for paleoenvironmental reconstructions and diagenesis analyses. Palaeogene deposits are characterized by an increase on palygorskite relative amounts in the distal parts of the basin as well as by higher structural order of the clay minerals in the Miocene sediments and lower structural order in Eocene sediments, pointing to a significant diagenesis contribution.
Os depósitos terciários da Bacia do Sado (no sudoeste de Portugal) comtemplam quatro principais unidades litoestratigráficas que resultam de uma deposição típica de uma bacia continental. Durante o Paleogénico, a Bacia do Sado era uma bacia fechada em que a mineralogia da fácies primária passou por mudanças significativas, que resultou numa extensa ocorrência de paligorskite. O preenchimento paleogénico da bacia do Sado é composto por sedimentos avermelhados detríticos grosseiros (conglomerados, arcoses, argilas e margas). Foram colhidas 28 amostras representativas dos afloramentos mais expostos das referidas unidades litoestratigráficas e analisadas, do ponto de vista mineralógico e químico, por DRX, FRX, respectivamente. Recorreu-se a análises SEM-EDS para calcular as fórmulas cristaloquímicas para os minerais argilosos identificados. Os resultados obtidos permitiram estabelecer associações mineralógicas para cada unidade, principalmente no que concerne os minerais argilosos. Estas associações foram interpretadas como marcadores litostratigráficos e possibilitaram a reconstrução paleoambiental e análise diagenética da bacia do Sado. De forma geral, os depósitos paleogénicos que preenchem a Bacia do Sado são caracterizados por um incremento na quantidade relativa de paligorskite no sentido proximal-distal, bem como por um aumento da ordem estrutural dos minerais de argila na mesma unidade litoestratigráfica, o que aponta para uma contribuição diagenética relevante.

Introduction -- Australian ð¹³Corg-isotope profiles about the Permian-Triassic (P/TR) boundary -- Strontium isotope seawater curve in the late Permian of Australia -- ð¹³Cco₃ AND ð¹⁸Oco₃ seawater profiles through the Permian-Triassic of Australasia -- Paleomagnetic stratigraphy about the Permian/Triassic boundary in Australia -- Synthesis.
The Permian-Triassic boundary mass extinction is the largest in the Phanerozoic and therefore is the major event in the Phanerozoic. The mass extinction cause is problematical but studying global geochemical and geophysical signatures about the Permian-Triassic boundary can provide insights into the cause of the mass extinction. Global events about the Permian-Triassic boundary are marked by changes in: ð¹³C values of carbon ; ⁸⁷Sr/⁸⁶Sr in unaltered marine calcite ; magnetic polarity. -- This study aims to identify these features in the sedimentary record and to test the ca libration of the Australian biostratigraphical schemes to the global geological timescale. The following features are found in the Permian-Triassic sediments of Australia: a ð¹³Corg in Total Organic Carbon excursion in 12 marine and nonmarine sections from Northwest to Eastern Australia ; a ⁸⁷Sr/⁸⁶Sr minimum in a composite section mainly from the Bowen Basin ; a magnetic polarity reversal in the Cooper Basin, central Australia. The Australian sections are thus time correlated, as follows: The negative ð¹³Corg excursion indicates the Permian-Triassic boundary and occurs: 1) in Eastern and Central Australia at the change from coal measures to barren measures with red beds at the beginning of the Early Triassic coal gap; 2) in Northwest Australia about the boundary between the Hyland Bay Formation and the Mount Goodwin Formation in the Bonaparte Basin and at the boundary between the Hardman Formation and the Blina Shale in the Canning Basin. The base of the negative ð¹³Corg excursion lies at or near the base of the Protohaploxypinus microcorpuspalynological zone. The ⁸⁷Sr/⁸⁶Sr minimum determined about the Guadalupian/Ochoan stage boundary in North America is found in the Bowen Basin about the boundary between the Ingelara and Peawaddy Formations. The ð¹³Corg excursion in the Cooper Basin is near a magnetic reversal within the Permo-Triassic mixed superchron. The implications of these findings include: confirmation of the traditional placement of the Permian-Triassic boundary at the coal measures/barren measures with redbeds boundary in Eastern Australia ; the linking of the the Permian-Triassic boundary to a mass extinction of plant species on land and the beginning of the Triassic coal gap indicated by the Falcisporites Superzone base that is coincident with the negative ð¹³Corg excursion ; a mass extinction causal model that links the ⁸⁷Sr/⁸⁶Sr minimum determined about the Guadalupian/Ochoan stage boundary to a fall in sealevel that led to changing global environmental conditions. The model invokes greenhouse warming as a contributing cause of the mass extinction.

Abstract:

After the establishment of the N-S Andib-Ganamub trough, the ubiquitous Lower Nosib subarkose was succeeded in the west by the Upper Nosib greywacke which indicates that orthogeosynclinal subsidence was already active in pre-Damara times. A pulse of NNE folding (F₁N) concluded this sedinentary cycle and was accompanied by amphibolite-grade metamorphism (M₁), occasional migmatisation (A₁), and later feldspar blastesis. This episode was most intense in the west, so that the overlying Damara rocks paraconformable in the east, are unconformable there. Martin's (1965) separation of the succeeding Damara basin into a western eugeosyncline and an eastern miogeosyncline applies very well to this area, though the separating hinge-line appears to have been located farther to the west (±80 Km) of the Kamanjab inlier, along the western flank of a N-S geanticlinal belt. The Lower Bakos semipelite and lenticular carbonate, thinning out against the eastern flank of this positive element controlling the deposition, may, prior to deformation, have created a transition between the western eugeosynclinal greywacke and the eastern miogeosynclinal Lower Otari carbonates. The fractured hinge-zone provided channels for the ascent of syndepositional intrusions and volcanics. Regional erosion following upwarping in the east caused a large influx of detritus into the Khomas furrow prior to the disconformable deposition of the Tillite Substage, which is the only reliable chronostratigraphic link between the base of the Upper Otavi and that of the Upper Bakos Series, the latter partially intertongueing with the succeeding Khomas Series. Gravitational creeping of the miogeosynclinal carbonates down the western slope of the upwarped Kamanjab inlier towards the sinking basin, produced the first folding (F₂O) in the east. Almost contemporaneously, buoyant uplifting forces, related to anatexis (A₂) along the axis of the eugeosyncline, created slopes sufficient to convey nappes (F₂S) of scarcely metamorphosed Damara schists towards the eastern foreland, overriding the miogeosyncline along the N-S Sesfontein Thrust. Eastern foredeeps were rapidly filled by the Mulden molasse. Steep slip folding (F₂S and F₄) in the cores and roots, and the formation of scattered domes at depth, controlled the successive structural evolution of the nappes. Large-scale axial undulations were later produced by orthogonally superposed F₃ folds striking east. The Damaran metamorphism (M₂ ), which outlasted deformation, has a Barrovian character and grades in the Damara sediments from amphibolite (sillimanite) grade in the west to greenschist (sericite- chlorite) grade in the east. In the previously dehydrated, deformed and metamorphosed, polymetamorphic (M₁/M₂ ) Nosib terrains, retrograde parageneses and transition granulites developed to the east and to the west of the Damaran hornblende-oligoclase isograd respectively. The Damaran tectono-thermal episode culminated in advanced migmatisation of the Khomas greywacke (possibly equivalent to the Salem granite-gneiss) and final anatexis (A₂ ) in the late-kinematic Ganias -Uhima (possibly equivalent to the Donkerhoek) granite, followed by widespread feldspar blastesis. The drop in rheomorphism in the deformed mass at the margin of the migmatite zone induced intense shearing and produced belts of mylonite and cataclastic gneiss. At a later stage, the Sesfontein Thrust was buffered against the Otavi dolomite relief and its speed of advancement reduced to match that of the erosion of its frontal toe, which now separates two completely different structural-stratigraphic domains: i) an eastern miogeosynclinal, feebly metamorphosed and volcanic-free domain (Damara System, Outjo Facies) deformed into non-basement-involving tectonites, overridden by ii) a western domain of suprastructural nappes and metamorphosed eugeosynclinal sediments (Damara System, Swakop Facies) deformed in response to basementinvolving tectonic processes promoted by deeply seated anatexis along the axis of the former eugeosyncline. The present model involves many stratigraphic revisions, one of the most important being that no rocks older than the Nosib Formation outcrop in the area and possibly along most of the Damara mobile belt in the western Kaokoveld.

Abstract:

Examination of stream and roadcut exposures of the Cowlitz Formation allows the selection of measured representative sections, and collection of fossils, from an area roughly defined by the intersection of the boundaries of Clatsop, Columbia, Tillamook and Washington counties in Oregon. The study defines the features of the local environment of deposition, correlates sections to derive a composite columnar section, and develops a checklist of species for both microfossils and megafossils of the Cowlitz Formation.
