Abstract: This paper presents a semi‐quantitative analysis of gravity‐driven deformation along the Namibian margin using extensive 2D depth converted seismic data. The geometries, internal characters and distribution of gravity‐driven systems were investigated through regional and detailed seismic studies. The research shows that surficial slumps are typically ca. 50 m thick and are characterised by contorted seismic facies commonly occurring along the slopes of the margin. They commonly funnel and cluster within high relief areas such as canyons and pre‐existing landslide scars. These contrast with coherent slides that are up to 2 km thick which extend laterally along the margin for tens to hundreds of kilometres. Slides preferentially occur in the proximal part of the margin and are constrained within the main margin depocenters. Here, high sedimentation rates and loading promote the generation of distinct, weak, overpressured layers that favour initiation of sliding of relatively coherent sediment masses. This research also shows that one‐third of volume of the post‐rift sediments on the Namibian margin were affected by slides and slumps. This demonstrates that gravity‐driven deformation is a key geological process that can strongly modify the evolution of rifted passive margins.

Abstract: & & Analyses of the sedimentary record, in particular the origin, routing and timing of deposition, can provide insight into a vast array of different geological processes over Earths history. However, understanding the provenance of very fine-grained sediments, particularly clay minerals, is typically challenging given their difficulty in being precisely dated. Yet the provenance of clay material may potentially provide greater detail on more distal detritus relative to other more conventional sand-sized provenance indicators (e.g. zircon). Triple quadrupole laser ablation inductively coupled plasma mass spectrometry, which allows in-situ Rb-Sr dating, offers several potentially significant advances in the geochronology of fine-grained Rb bearing mineral phases. Nonetheless, dating of very fine-grained sediments, especially those formed in the Phanerozoic after the terrestrial vegetative evolution, is challenged by the inevitable mixing of potentially different generations of Rb bearing minerals within the volume ablated by the laser (~90,000 & #181 m& sup& & /sup& ). Rb-rich minerals will dominate the isotopic budget of any mixture and may help to constrain age components within the s le. In this study, we present in-situ Rb-Sr data of six variably biostratigraphically constrained Paleozoic shale s les from the Barnicardy-1 drill core (Canning Basin, Western Australia). We develop a new Monte-Carlo modelling approach to improve the constraint on Rb-Sr ages by confining the range of initial Sr-ratios from analysed mixtures via a priori knowledge of the s les stratigraphic level.

Abstract: In the northern Perth Basin (Western Australia), the Early Triassic Kockatea Shale is the primary petroleum source rock. Possible source rocks in the Northern Carnarvon Basin are more varied and include the Upper Jurassic Dingo Claystone as well as the Early Triassic Locker Shale. Biomarker analyses were conducted on petroleum s les from these basins to understand the nature of the petroleum systems. Many of the analysed petroleum s les contain carotenoids (okenane, chlorobactane and isorenieratane) derived from photosynthetic sulfur bacteria, suggesting that their source rocks were deposited under conditions of photic zone euxinia (PZE) and/or derived from microbialites. In the northern Perth Basin, the major lithofacies contributing to the source rock are dark coloured mudstones deposited under PZE conditions and/or derived from microbialites. In the southern Perth Basin, the potential source rock is either Permian, Jurassic or Cretaceous in age as indicated by the low concentrations or absence of carotenoids and the Triassic biomarker n -C 33 alkylcyclohexane. There is also a possibility that the Lower Triassic Locker Shale is the source rock of petroleum in the Tubridgi field on the Peedamullah Shelf of the Northern Carnarvon Basin, based on the similarity of biomarkers to Perth Basin petroleum sourced from the Kockatea Shale. However, the possibility of charge from the Upper Jurassic Dingo Claystone cannot be entirely excluded. Supplementary material: biomarker dataset is available at 0.6084/m9.figshare.c.6452153

Abstract: With the increased size and complexity of seismic surveys, manual labeling of seismic facies has become a significant challenge. Application of automatic methods for seismic facies interpretation could significantly reduce the manual labor and subjectivity of a particular interpreter present in conventional methods. A recently emerged group of seismic interpretation techniques is based on deep neural networks. These approaches are data-driven and require large labeled data sets for network training. We have developed a deep convolutional autoencoder for unsupervised seismic facies classification, which does not require manually labeled ex les. The facies maps are generated by clustering the deep-feature vectors obtained from the input data. Our method yields accurate results on real data and provides them instantaneously, which allows an interpreter to identify the dominant seismic features. The proposed approach opens possibilities to analyze geologic patterns in real time without human intervention.

Abstract: & & The North West Shelf of Australia has experienced numerous rift events during its prolonged evolution that most likely started in the Lower Palaeozoic and continued through to the formation of the present day passive margin in the Lower Cretaceous. & Carboniferous and Permian is associated with rifting of the Lhasa terrane, a phase extension in the Lower and Middle Jurassic associated with the separation of the Argo terrane Upper Jurassic to Lower Cretaceous extension culminated in the separation of Greater India and Australia.& Investigations based on interpretation of extensive, public domain seismic data, combined with numerical mechanical modelling, demonstrate that crustal structure, rheology and structural fabrics inherited from older events exert a significant control on the architecture of younger rifts.& & & & Defining the older, more deeply buried rift episodes is challenging, but with seismic data that now images deeper structures more effectively, it is clear that NE-SW oriented Carboniferous to Permian aged rift structures control the overall geometry of the margin. & Variations in the timing, distribution and intensity of that rift may account for some of the complexity that governs the Triassic & #8211 a failed arm of the rift system might account for the accumulation of thick sequences of fluvio-delatic sediments in an apparent post-rift setting, while active deformation and igneous activity continued elsewhere on the margin.& & & & A renewed phase of extension began in the latest Triassic in the western part of the Northern Carnarvon Basin, but became progressively younger to the NE. & High-resolution mechanical numerical experiments show that the dual mode of extension that characterises the Northern Carnarvon Basin, where both distributed and localised deformation occurs at the same time, is best explained by necking and boudinage of strong lower crust, inherited form the Permian rift event, proximal to the continental margin, and a subdued extensional strain rate across the distal extended margin.& A very clear and consistent pattern of ENE oriented extension, which interacts obliquely with the older NE-SW oriented Permian aged structures, is apparent across the whole of the Northern Carnarvon Basin and extends north east into the Roebuck and Browse Basins. & This is at odds with the NW-SE oriented extension predicted by the separation of the Argo terrane which occurs at this time.& This may be explained by the detached style of deformation that characterises the Mesozoic interval.& Alternatively, the separation of Greater India may have exerted a stronger influence on the evolution of the margin during the Jurassic than hitherto recognised.& &

Abstract: With the rapid development of deep learning technologies, data-driven methods have become one of the main research focuses in geophysical inversion. Applications of various neural network architectures to the inversion of seismic, electromagnetic, gravity and other types of data confirm the potential of these methods in real-time parameter estimation without dependence on the starting subsurface model. At the same time, deep learning methods require large training datasets which are often difficult to acquire. In this paper, we present a generator of 2D subsurface models based on deep generative adversarial networks. Several networks are trained separately on realistic density and stratigraphy models to reach a sufficient degree of accuracy in generation of new highly detailed and varied models in real-time. This allows for creation of large synthetic training datasets in a cost-effective manner, thus facilitating the development of better deep learning algorithms for real-time inversion and interpretation.

Abstract: The Offshore North Sumatra Basin is an underexplored basin. Only a limited amount of exploration has occurred in the past resulting in the discovery of one economic field that is currently producing, a number of uneconomic discoveries and some unsuccessful wells. This is reflected in limited geological studies of the area. This paper demonstrates the importance of N-S trending faults associated with Basin formation in the Oligocene, continued fault activity in the late Oligocene and both compressional and extensional reactivation in the Miocene.
