Inflated pahoehoe lavas from the Sangamner area of the western Deccan Volcanic Province

摘要

Notwithstanding the recent advances in petrology, geochemistry and determining the age of the Deccan Traps, there is no unanimity regarding the mechanism of their emplacement. Some of the basic questions regarding the source of the Deccan lavas, their actual eruption, and their post-eruptive behaviour have not been answered. In this paper, we describe the structure, physical characters and emplacement of some lava flows in the Sangamner area of the Deccan Volcanic Province (DVP). Our observations suggest that inflation (thickening by endogenous growth) was an important mechanism in the emplacement of flows in this area; and probably also in other parts of the DVP.
