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 ...

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Description of Flavicapitulum gen. nov. and two new species of Marmoreocelis from thermal habitats in the Americas

Journal of Phycology, EarlyView.
Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, EarlyView.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Sector collapse of mud volcanoes, Azerbaijan

, 2011
Field data collected from mud volcanoes in Azerbaijan are used to describe a process in mud volcano development that involves portions of the constructional edifices collapsing outwards in 'thin-skinned' slides. These events create kilometre-scale scarps

A Wild Emmer Wheat B3 Transcription Factor Regulates Seed Growth and Nutrient Allocation

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed weight (SW) and nutrient allocation are key determinants of yield and grain quality in wheat, yet the regulatory basis of naturally occurring variation in these traits remains poorly resolved. Wild emmer wheat (Triticum dicoccoides), the progenitor of modern wheat, retains extensive eco‐geographically structured genetic diversity that was

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 ...
