In the past few decades, late Cretaceous Deccan volcanism witnessed extensive researches, focused on nature, variety and genesis of magma, emplacement span [entail Cretaceous /Palaeogene (K/Pg) transition] and attendant faunal crisis; however several issues remain to be addressed. In this gamut, researches in the past five years have been reviewed, encompassing petrochemical, Nd-Sr-Pb isotopic, and geochronology studies to comprehend origin, age and duration of volcanism and attendant K/Pg transition events. Low/high TiO 2 tholeiites of Deccan Traps and associated rocks from a rifted basin revealed existence of varied mantle sources for synchronously formed tholeiitic and alkaline magma involved sub-continental lithospheric mantle. Moreover, later magma type ascended with faster rate through the lithosphere and subsequently led to rapid gaseous release, accounted for the Cretaceous/Palaeogene boundary (KPB) mass extinction. Flow-by-flow palaeomagnetic measurements for the Mandla basalt revealed multiple magnetic polarity events: implying for C29n-C28rC28n magnetostratigraphy.
