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.

Cross-species comparison of ultramafic rock bio-accelerated weathering performance [PDF]
Scientific ReportsCarbon mineralization sequesters atmospheric CO2 by reacting it with cations from rock weathering to form carbonates. However, natural rates are too slow, and acceleration with chemical or mechanical methods is expensive. Microbial processes (acidolysis,

Carbon Mineralization in Fractured Mafic and Ultramafic Rocks: A Review. [PDF]
Rev GeophysAbstractMineral carbon storage in mafic and ultramafic rock masses has the potential to be an effective and permanent mechanism to reduce anthropogenic CO2. Several successful pilot‐scale projects have been carried out in basaltic rock (e.g., CarbFix, Wallula), demonstrating the potential for rapid CO2 sequestration.

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.
