The Central Atlantic Magmatic Province (CAMP) hosts laterally extensive basalt flows of significant thicknesses, providing potential opportunities for carbon storage to mitigate CO2 emissions. Here, we examine a distinct basalt flow in the Newark Basin, the Orange Mountain Basalt which exhibit highly vesicular flow boundaries, but with interflow zone properties that where well-sealed, could be effective as CO2 reservoirs. Although the flows are variably exposed in outcrops, complete sections of Orange Mountain Basalt have been drilled, cored, and logged at the Martinsville site (Newark Basin Coring Project). We leverage the data to investigate the structure of the interflows zones, and compare the petrophysical and geochemical properties to understand the relationships between their porosity, permeability, rock strength and geochemical composition across different scales. Our results will provide insight into the potential of CAMP basalts to be effective and secure reservoirs for long-term CO2 storage, and improve the broader understanding of similar geological deposits worldwide, extending the range of this potential storage solution for mitigating CO2 emissions.
