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 .

Carbon Mineralization in Fractured Mafic and Ultramafic Rocks: A Review. [PDF]

Rev Geophys
Mineral 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 ...

Cross-species comparison of ultramafic rock bio-accelerated weathering performance [PDF]

Scientific Reports
Carbon 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,

Field availability and mobility of metals in Ferralsols developed on ultramafic rock of Niquelândia, Brazil

, 2021
Ultramafic (UM) rocks are defined as igneous rocks that contain more than 90% of mafic minerals. Soils derived from ultramafic rock are generally nutrient-deficient and have concomitant high concentrations of potentially phytotoxic trace elements (Ni, Cr,
