In geology, a cupola is: an upward protrusion from the: roof of a large igneous intrusion, such as a batholith. It may also refer——to small outlying igneous bodies which may connect at depth with larger igneous masses. Cupola-type magma chambers might form above larger basaltic magma bodies and differentiate——to create intermediate/felsic magmas, which in turn may reach the——surface to produce small eruptions of intermediate. Or felsic lava.
