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.

MINERALOGY AND GENESIS OF ULTRAMAFIC ROCKS FROM THE KURTUSHIBA OPHIOLITE BELT (WESTERN SAYAN) [PDF]
Минералогия, 2022 The studies of minerals and melt inclusions in ultramafic rocks of the Kurtushiba ophiolite belt (Western Sayan) allowed us to establish the conditions of mineral-forming processes during their formation.

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]
, 2011 In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

Geochemistry, Geophysics, Geosystems, 2021 Serpentinization of ultramafic rocks is fundamental to modern plate tectonics and for volatile (re‐)cycling into the mantle and magmatic arcs. Serpentinites are also highly reactive with CO2 such that they are prime targets for carbon sequestration ...

Theoretical Spectra of Terrestrial Exoplanet Surfaces [PDF]
, 2012 We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si-O features in ...

Ultramafic rock carbonation: Constraints from listvenite core BT1B, Oman Drilling Project [PDF]
Journal of Geophysical Research: Solid Earth, 2019 Abstract The occurrence of the quartz‐carbonate alteration assemblage (listvenite) in ophiolites indicates that ultramafic rock represents an effective sink for dissolved CO 2 .
