Earth Science, Systems and Society, 2021 Large Igneous Provinces, and by extension the mantle plumes that generate them, are frequently associated with platinum-group element (PGE) ore deposits, yet the processes controlling the metal budget in plume-derived magmas remains debated.

CRUST AND MANTLE OF THE BAIKAL RIFT ZONE FROM P- AND S-WAVE RECEIVER FUNCTIONS
Геодинамика и тектонофизика, 2017 We have obtained P-wave and S-wave receiver functions for 10 broadband seismograph stations in the Baikal rift zone (BRZ) and inverted them for seismic velocity models of the crust and upper mantle.

Геодинамика и тектонофизика, 2015 The work considers the mechanism of upwelling of the basaltic melt to the surface and the reason of its stoppage in the crust. The process of stoppage, probably, is controlled by ratio between density of the basaltic melt and density of the crust.

Monogenetic Near‐Island Seamounts in the Galápagos Archipelago
Geochemistry, Geophysics, Geosystems, 2020 Rarely have small seamounts on the flanks of hotspot derived ocean‐island volcanoes been the targets of sampling, due to sparse high‐resolution mapping near ocean islands.

Does depleted mantle form an intrinsic part of the Iceland plume? [PDF]
, 2003 Icelandic basalt ranges in composition from voluminous tholeiite, erupted in the rift zones, to small-volume, mildly alkaline basalt erupted off-axis.

Acute effect of detergent on lipid alteration in freshwater gastropod Bellamya bengalensis (Lamarck)
Environment Conservation Journal, 2013 The freshwater gastropod Bellamya bengalensis exposed to 69.18ppm concentration of detergent (Tide) on lipid content in the tissue of foot, mantle and digestive glands for 96 hours exposure.

Pulsated Global Hydrogen and Methane Flux at Mid‐Ocean Ridges Driven by Pangea Breakup
Geochemistry, Geophysics, Geosystems, 2020 Molecular hydrogen production occurs through the serpentinization of mantle peridotite exhumed at mid‐ocean ridges. Hydrogen is considered essential to sustain microbial life in the subsurface; however, estimates of hydrogen flux through geological time ...
