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.

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2020 The Konawe region is part of the Sulawesi Southeast Arm ophiolite belt where ultramafic rocks are exposed in the form of dunite and peridotite. The formation of nickel deposits is closely related to the weathering process of ultramafic rocks as a source ...

Reflectance spectroscopy and analytical techniques in characterising PGE-bearing host rocks
Geosystems and Geoenvironment, 2023 The Mettuppalaiyam mafic and ultramafic complex (MUC) is part of the Southern Granulite terrain in India. MUC is one of the promising sites for Ni-Cu-Cr and Platinum Group of Elements (PGE) mineralisation.

Ultramafic xenoliths from the Bearpaw Mountains, Montana, USA: evidence for multiple metasomatic events in the lithospheric mantle beneath the Wyoming craton [PDF]
, 2004 Ultramafic xenoliths in Eocene minettes of the Bearpaw Mountains volcanic field (Montana, USA), derived from the lower lithosphere of the Wyoming craton, can be divided based on textural criteria into tectonite and cumulate groups. The tectonites consist

Ultramafic Rock Carbonation between 40° and 255° C
Goldschmidt Abstracts, 2020 Carbonation of ultramafic rocks variably leads to the formation of silica-carbonate (listvenite), talc-carbonate (soapstone) or magnesite deposits, thereby providing insights into carbon cycling in marine and terrestrial hydrothermal systems, gold and ...
