Carbon sequestration in geologic formations is a promising strategy that enables long-term storage of CO2. Continental flood basalts are an attractive storage option, primarily due to their reactivity. In 2009 a Basalt Pilot study was initiated in the Columbia River Basalt where ~1000 MT of CO2 was injected ~850 m into the subsurface. Two years later, 50 sidewall cores were collected from the injection zone and characterized for evidence of CO2 mineralization. This effort summarizes those key findings associated with seven sidewall cores
