摘要：The Deccan Volcanism during the Late Cretaceous was a globally significant geological event, coinciding with the Cretaceous-Paleogene Boundary. The magma outpouring occurred in three phases. The flora that got preserved during the first phase (30N) was a mixed gymnosperm and angiosperm flora ranging from dry to moist forest vegetation. The second phase (29R) flora is mostly represented by pteridophytes and tropical to sub-tropical angiosperm plant families. The palynofloral records from the third phase (29N) are mostly tropical angiosperms. This floral turn-over is driven by latitudinal shifting of the Indian plate from sub-tropical to tropical zone. It is surmised that the latitudinal shifting of Indian plate during the span of 4 Ma during the Late Maastrichtian led to the development of new ecological conditions favoring successful dominance of angiosperms over gymnosperms.
