| Session Description | The emplacement of mafic and ultramafic magmas into the crust at anorogenic settings throughout geologic time contributes to crustal growth, crustal recycling, and continental breakup. The mechanisms and rates of the eruption of flood basalts, formation of oceanic plateaux, and mafic dyke swarms are first order problems in the geosciences and are, in part, related to the complex interplay between tectonics and the thermal conditions of the mantle. Moreover, flood basalt provinces and their oceanic equivalents are often sites of ore-bearing layered intrusions and ferroan (A-type) granitoids, whereas the anomalously thick crusts of oceanic plateaux hinder their complete subduction and contribute to continental growth. This session will focus on constraining the tectonomagmatic processes that contribute to the formation of intraplate magmatic events, such as continental flood basalt provinces, oceanic plateaux, A-type granites, and giant radiating mafic dyke swarms throughout Asia-Pacific and is aimed at geochemists, petrologists, geologists, tectonophysicists and numerical modelers interested in the relationship between geodynamics and magma genesis. |
