In petrology and geochemistry, an incompatible element is one that is unsuitable in size and/or charge to the cation sites of the minerals of which it is included. It is defined by the partition coefficient between rock-forming minerals and melt being much smaller than 1. During the fractional crystallization of magma and magma generation by the partial melting of the Earth's mantle and crust, elements that have difficulty in entering cation sites of the minerals are … Nettet20. jan. 2005 · HFSE depletions are produced because LILE are more readily partitioned into H 2 O-rich fluids/melts released by devolatilization or partial melting of slab rocks. Fluids released from the slab transfer this depletion to the overlying mantle wedge and trigger flux-melting of peridotite leading to arc volcanism [ Kelemen et al. , 2003a ; …

Nettet2. nov. 2024 · Our investigation arrives at the conclusion that the NMO as a whole cannot be considered as 100% subduction or 100% non-subduction origin. It is indeed a combination of both.
