Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Clinicogenetic Characterization of H Syndrome in a South African Child

Pediatric Dermatology, EarlyView.
ABSTRACT H syndrome is a rare autosomal recessive genodermatosis caused by loss‐of‐function SLC29A3 variants, combining hyperpigmented indurated plaques and hypertrichosis with life‐threatening autoinflammation. We report a 5‐year‐old South African girl of first‐cousin parents who presented with hyperinflammation mimicking macrophage activation ...

TRAZAS FOSILES EN BARRAS SUBMAREALES DE LA FORMACION BALCARCE (CAMBRICO/ORDOVlCICO), CABO CORRIENTES, MAR DEL PLATA, ARGENTINA

Publicación Electrónica de la Asociación Paleontológica Argentina, 2015
Cambrian/Ordovician trace fossil assemblages from the Balcarce Formation are described. In the Cabo Corrientes outcrops at the Atlantic coast, four sedimentary facies are distinguished as follows: a) Pebble Sandstone Facies with progradation surfaces and

Sedimentary environment and facies types of Eocene Baoshi Formation in Pingbei area, Pinghu slope belt, Xihu Sag, East China Sea Basin

Shiyou shiyan dizhi
The unclear understanding of the sedimentary environment and facies of the Baoshi Formation in the Pingbei area of the Pinghu slope belt, Xihu Sag, East China Sea Basin, has restricted the evaluation of the Baoshi Formation reservoirs and source rocks in

Not all rhodoliths need a bed–depositional mechanisms in shallow water Sporolithon nodosum rhodoliths from the Whangaparaoa peninsula (North Island, New Zealand)

Sedimentology, EarlyView.
ABSTRACT Rhodoliths, formed by crustose coralline algae (CCA), are prominent components in carbonate platform deposits, contributing to the characteristic rhodalgal facies. Their formation is influenced by both biological and physical factors, and under specific conditions, they can accumulate, forming extensive rhodolith beds.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...
