Mechanisms of magma transport and storage in the lower and middle crust—magma segregation, ascent and emplacement
AR Cruden, RF Weinberg - Volcanic and igneous plumbing systems, 2018 - Elsevier
Felsic and mafic magmas in continental crustal settings are derived by melting of the lower
crust and mantle, respectively. This occurs in subduction zone, collisional, extensional and …
