Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Natural hydrogen potential and basaltic alteration in the Asal–Ghoubbet rift, Republic of Djibouti
BSGF - Earth Sciences Bulletin, 2023 The Asal–Ghoubbet active rift in the Republic of Djibouti is a site of interest for geothermal energy and natural hydrogen, and previous studies have indicated that dihydrogen (H2) emanates from this rift.

Temperatures in ambient mantle and plumes: Constraints from basalts, picrites, and komatiites [PDF]
, 2006 Several methods have been developed to assess the thermal state of the mantle below oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of erupted lavas. One leads to the conclusion that mantle potential temperature (i.e.

Research progress on key technologies of CO2 storage in basalts
Shuiwen dizhi gongcheng dizhi, 2022 Geological storage of CO2 in basalts provides a new and potentially significant option for carbon capture and storage (CCS). So far, there are only three demonstration projects in the world, namely Nagaoka in Japan, Wallula in the United States of ...

Ar-40/Ar-39 dates from the West Siberian Basin: Siberian flood basalt province doubled [PDF]
, 2002 Widespread basaltic volcanism occurred in the region of the West Siberian Basin in central Russia during Permo-Triassic times. New Ar-40/Ar-39 age determinations on plagioclase grains from deep boreholes in the basin reveal that the basalts were erupted ...
