Magma petrogenesis
Examining the petrogenesis of magmas over time both in cold and warm subduction zones.
Dehydrating the downgoing plate (slab) promotes mantle melting, generating water-rich magmas. Subduction-related magmas can thus be understood as partial melts from the hot asthenospheric mantle wedge fluxed by the fluids released from the downgoing plate. Here, I focuse on the genesis of melts produced in cold and warm subduction zones (arc, back-arc basin, rear arc) since their inception to further comprehend how they form and evolve with time. I also examine fore-arc magmas (such as adakites, forearc basalts, boninites), as these rare lavas can provide critical constraints on shallow processes that occur above a long-lived subduction zone or during subduction infancy.
