Magma hybridization in the middle crust: Possible consequences for deep-crustal magma mixing

The 465 Ma Svarthopen pluton in north-central Norway was emplaced under middle-crustal conditions (∼700 MPa) into metasedimentary rocks of the Helgeland Nappe Complex. The pluton is characterized by zones of mingling and mixing of gabbro/diorite with peraluminous, garnet-bearing biotite granite. Var...
