Which process is thought to generate most felsic magmas?
A)Decompression melting in a continental rift zone
B)Crystal settling during magmatic differentiation
C)Heat from basaltic magma partially melting overlying crust
D)Friction along the crust in a convergent plate boundary

Question

Quizplus · Accepted Answer

Heat from basaltic magma partially melting overlying crust is thought to generate most felsic magmas through a process called assimilation. Basaltic magma rises through the crust and assimilates (partially melts) the surrounding felsic rocks, ultimately producing a more silica-rich (felsic) magma.
