In situ carbon mineralization in ultramafic rocks: Natural processes and possible engineered methods

Abstract In this invited review, we summarize the main results of ongoing research on “ in situ ” carbon mineralizationin ultramafic rocks, including outcropstudies in Oman (e.g., [1, 2]), investigation of carbon mass transfer in subduction zones from the Oman Drilling Project (e.g., [3-7]), laboratory investigations (e.g., [8-12]) and numerical modeling (e.g., [13-17]) of the pressure of crystallization and reaction-driven cracking, and assessment of the rate, cost and capacity of various proposed methods for engineered carbon mineralization[18, 19].
