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 ...

A Diapiric Structure Near Sable Island - Scotian Shelf

Atlantic Geology, 1970
A diapiric structure was discovered on the Scotian Shelf at a point 45 km north-northeast of Sable Island, by means of continuous seismic-reflection techniques. The structure is dome-shaped, may contain an evaporitic core, and intrudes rocks considered to be of Cretaceous age. The area of structural disturbance is at least 10 km in diameter.

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

Study on the planar structure characteristics of mud diapirs in Rio del Rey basin , West Coast of Africa(非洲西海岸里奥-德雷盆地泥底辟平面地质结构特征研究)

Zhejiang Daxue xuebao. Lixue ban
The Rio del Rey basin, located in the eastern margin of the Niger Delta Basin in West Africa, develops large-scale mud diapirs. There are some disputes about the activity time and mechanism of the diapirs. Based on the detailed interpretation and mapping

Contrastive Analysis of Deep-Water Sedimentary Architectures in Central West African Passive Margin Basins During Late-Stage Continental Drift

Journal of Marine Science and Engineering
The Lower Congo Basin (LCB) and the Niger Delta Basin (NDB), two end-member deep-water systems along the West African passive margin, exhibit contrasting sedimentary architectures despite shared geodynamic settings.

3D Vs ambient noise tomography of the 2016 Mw 6.4 Meinong Earthquake source region in Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2017
Mw 6.4 Meinong earthquake occurred on 6 February 2016 in southern Taiwan, resulting in more than one hundred casualties and several collapsed buildings. The aftershocks occurred mostly at mid-to-lower crustal depths (10 - 30 km), related to a blind fault

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

New ideas on the tectonic of the Kurveleshi anticlinal belt in Albania, and the perspective for exploration in its subthrust

Petroleum, 2015
The external thrustbelt of Albania consists of some tectonic zones (Ionian, Kruja and Krasta-Cukali zones), that are westward overthrust, with a large amplitude (50–100 km), above the Apulian platform and South Adriatic Basin.

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...
