Mafic Granulites in the Crystalline Core of the Neybaz Complex [PDF]
پترولوژیIntroductionFormation and evolution of the continental crust is one of the fundamental subjects in Earth sciences studies, as these processes usually occurred during the Archean and Proterozoic (e.g., Condie, 1980; Taylor and McLennan, 1981).

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

Post-Hercynian ultrahigh-temperature tectono-metamorphic evolution of the Middle Atlas lower crust (central Morocco) revealed by metapelitic granulite xenoliths [PDF]
Solid EarthThe study of metapelitic sillimanite- and garnet-bearing granulite xenoliths brought to the surface by the basanite of the 650 ka Tafraoute maar shed new light on the lower crust of the Tabular Middle Atlas (Morocco).

Meteoritics &Planetary Science, EarlyView.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Ductile Extrusion Triggered by Continental Collision in NE Brazil
Terra Nova, EarlyView.ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...
