[HTML][HTML] From peridotite to listvenite–perspectives on the processes, mechanisms and settings of ultramafic mineral carbonation to quartz-magnesite rocks
Listvenites form by metasomatic transformation of variably serpentinized peridotites to
carbonate-quartz rocks due to extensive reaction with CO 2-bearing aqueous fluids. This …
