Abstract

Summary

Deccan Basalts of India are being studied for large-scale permanent sequestration of CO2. However, we observed that the characteristics of these basalts are different than other LIPs. We report anomalous secondary mineralization leading to the anomalous elastic behavior of the rock matrix. These results have serious implications for upcoming CCS projects in this region. It is suggested that the enhanced porosity caused by the formation of secondary minerals could play a crucial role in the fluid movement in long-term CO2 sequestration in Deccan LIP. To summarize, this paper provides insight into the fate of CO2 in reactive mafic basalt formations of Deccan LIP.
