Mechanism of crustal extension in the Laxmi Basin, Arabian Sea

Geodesy and Geodynamics, 2015
Continental rifting and magmatism has been extensively studied worldwide as it is believed that continental rifting, break up of continents and associated magmatism lead to genesis of new oceanic crust.

Constitution of Oceanic Crust and Ocean Ridge Magmatism

Journal of Geography (Chigaku Zasshi), 2003
Volumetrically, magmatism at spreading axes occupies more than 60% of present day volcanism, and oceanic crust generated there covers more than two thirds of earth surface. Therefore, studies of the oceanic crust and magmatism at spreading axes yield significant insights to understanding earth evolution. Recent studies on oceanic crust through drilling,

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

The Oceanic Crust

, 1975
I attempt in this article to put in context recent studies of the oceanic crust, studies which led to the drilling of the uppermost few hundred metres of the igneous rocks of the crust on Leg 37 of the Deep Sea Drilling Project.

PALEOGUYOTS OF THE DZHIDA ISLAND-ARC SYSTEM OF THE PALEO-ASIAN OCEAN: STRUCTURE, COMPOSITION, AGE, COMPARATIVE ANALYSIS WITH SIMILAR STRUCTURES OF THE CENTRAL ASIAN FOLD BELT, GEODYNAMIC MODELS

Геодинамика и тектонофизика
The Dzhidot and Urgol large paleoguyots and a number of smaller fragments of oceanic islands close in composition to the paleoguyots within the accretionary-collisional structures of the north-eastern part of the Central Asian orogenic belt are ...

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

Spatial Heterogeneity of Pore Structure in the Crustal Section of the Samail Ophiolite: Implications for High VP/VS Anomalies in Subducting Oceanic Crust

Geophysical Research Letters
Seismic surveys along subduction zones have identified anomalously high ratio of P‐ to S‐wave velocity (VP/VS) in the subducting oceanic crust that are possibly due to the presence of pore water.
