MCMonica CamposKing Fahd University of Petroleum and Minerals MMMobeen MurtazaKing Fahd University of Petroleum and Minerals HKHasan J. KhanKing Fahd University of Petroleum and Minerals

Key Points

This research aims to investigate CO₂ mineralization and its implications for carbon storage in Saudi Arabian basalts.
Experimental assessment of CO₂ mineralization in different basalt types.
Comparison of scoriaceous basalt with dense basalt in terms of porosity and carbonate formation.
Scoriaceous basalt exhibited greater porosity development than dense basalt.
Higher Ca²⁺ release and TIC accumulation were observed in scoriaceous basalt.
Enhanced carbonate formation in scoriaceous basalt indicates its superior potential for long-term CO₂ storage.

Abstract

Experimental workflow and key findings of CO₂ mineralization in Saudi Arabian basalts. Scoriaceous basalt showed greater porosity development, Ca²⁺ release, TIC accumulation, and carbonate formation than dense basalt, highlighting its higher potential for long-term CO₂ mineral storage.
