Abstract: Large Igneous Provinces (LIPs) are considered the most extensive magmatic events on Earth, during whichmassive amounts of melt erupted in a short period (1 Ma) of time. Traditionally, the origin of LIPs is linked with mantleplumes. However, our analysis reveals that extensive melting of ambient mantle regimes can also lead to the formationof LIPs, and this further signifies the role of plate tectonics in LIP events. In this talk, I will discuss our efforts to unravelthe relationship between LIP events in the continents and their implications on the breakup mechanisms ofsupercontinents. Additionally, I will highlight the thermal differences observed in the source mantle of oceanic andcontinental LIPs and their potential implications on supercontinent cycles. Moreover, I'll also discuss our ongoing effortsto unravel the heterogeneities and volatile budget of the deep mantle sources of the Deccan LIP in India using advancedgeochemical and isotopic tools. Along with teaching plans, the presentation will also provide a concise overview of ourresearch in various geological domains, including Archean granite-greenstone belts, layered gabbro-anorthositecomplexes, Cenozoic subduction zones, Venusian anorthosites, Precambrian dyke swarms, and oceanic plume eventsrecorded in Tethyan ophiolite fragments.\n\nMeeting id: 944 2649 3601\nPasscode: 070134\n
