Abstract

The present paper records some of the remnant vertical and horizontal to sub-horizontal gas migration channels in the Deccan Trap basalts from the vertical escarpment face at Bhaja Caves. These could have developed during the eruption, migration, inflation and overriding of the basaltic lava flows. The accumulated entrapped gases and volatiles of the lower flows migrated vertically and laterally into offshoots along the upper contacts or within the flow itself. In most cases, the vesicles are found to be empty as well as filled with the secondary minerals.
