Log-based identification of sedimentary facies in coal measures in the southern Wuxiang block, Shanxi Province, China

Meitian dizhi yu kantan
ObjectiveThe Carboniferous and Permian coal-bearing strata in the southern Wuxiang block, Qinshui Basin, Shanxi Province, China contain abundant coalbed methane (CBM) resources. To develop intelligent discrimination technology for CBM exploration in this

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

The Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

FIRST EVIDENCE OF PALEO-TSUNAMI DEPOSITS OF A MAJOR HISTORIC EVENT IN ECUADOR [PDF]

Science of Tsunami Hazards, 2014
The Ecuadorian shoreline is considered highly susceptible by impacts of tsunamis triggered by marine quakes or submarine landslides occurring close or nearby the subduction zone between the Nazca, Caribbean and South American plates. Since 1877 one dozen

Main controlling factors and predictive models for the study of the characteristics of remaining oil distribution during the high water-cut stage in Fuyu oilfield, Songliao Basin, China

Energy Exploration & Exploitation, 2018
The distribution of remaining oil is affected by a number of geological and engineering factors. However, previous studies have mainly focused on the effect of a certain factor or some factors on the distribution of remaining oil.

THE PROBLEMS OF IDENTIFICATION OF THE NEO-PLEISTOCENE GLACIAL MEGA-FLOOD DEPOSITS IN THE ALTAI MOUNTAINS REGION

Лëд и снег, 2015
Similarities and differences of glacial megaflood deposits and deposits of other genetic types of Gorny Altai are considered in the paper. Diluvial sedimentary complex includes (from bottom to top): debris flow facies of boulder-pebbles with giant ...

A new occurrence of tetrapod footprints from the Late Triassic of the Candelária Sequence, Brazil

The Anatomical Record, EarlyView.
Abstract The Hyperodapedon Assemblage Zone of the Candelária Sequence (Santa Maria Supersequence, Paraná Basin) preserves one of the most significant Late Triassic continental vertebrate assemblages in southern Brazil. Despite the relatively well‐documented body fossil record from this interval, ichnological records remain comparatively scarce.

Application of Seismic Reservoir in Sedimentary Facies [PDF]

Proceedings of the 2015 2nd International Workshop on Materials Engineering and Computer Sciences, 2015
Fracture system is main geological factor to control the formation and preservation of oil gas reservoir. And deepening the understandings to the formation and evolution of petroleum basin fracture are necessary for us to know the geological condition used for form the oil gas in petroleum basin and explore the control effects of fracture in ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Efficient Sedimentary Facies Recognition Using Vision Transformer and Weakly Supervised Deep Multi-View Clustering

IEEE Access
Sedimentary facies recognition plays a crucial role in geological exploration and oil-gas resource evaluation. However, traditional recognition methods are limited by their ability to extract local features and efficiently utilize unlabeled data, making ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
