Tittel

MAPLES - MAgma PLays with sEdimentary rockS - 301096

Vitenskapelig sammendrag

The intrusive parts of Large Igneous Provinces (LIPs) have been shown to contribute enormously to the gas budgets that such events emit to the atmosphere, and subsequently how they help force climate change. Large sill intrusions in LIPs, with vast surface areas, interact with host sediments in volcanic basins and generate a number of gas species, which are released into the atmosphere by venting episodes. Current estimates are based solely on the metamorphic reactions within host rocks, without any quantification of within sill reactions that occur within the cooling magma bodies themselves. Such reactions inside the cooling and crystallising magma, could have the possibilities to add further to the gas budgets or may locally result in gas sinks within the system? MAPLES addresses this knowledge shortfall, using a focused geochemical and petrologic study on the processes occurring within the magmatic portions of this dynamic system. To provide a balanced understanding, MAPLES will target three types of host rock lithology: sills in evaporites and carbonates (Obj.1), sills in clastic lithologies (Obj.2), and sill-petroleum systems (Obj.3). After focusing on the types of reactions and their scales occurring in the intrusions within each scenario, a synthesis will be obtained by a balanced evaluation and comparison of the end-member scenarios (Obj.4). MAPLES will improve our understanding of the processes occuring during LIP emplacement, and the associated gas fluxes, where different host rocks make up the main parts of the sedimentary basins through which the LIPs are emplaced. Importantly also, MAPLES will clarify the boundaries between melt-stage and sub-solidus processes of sill-sediment interaction occurring within the sills, defining new geochemical tracers to detect and quantify these interactions. LIP-related severe forcing on the atmospheric gas budgets is the best analog case-study for the changes atmosphere is undergoning in the Anthropocene.
