nonvolcanic
Lacking molten origins
Nonvolcanic describes geological features, regions, or processes not created by or related to volcanic activity.
A nonvolcanic island forms through coral accumulation or tectonic uplift rather than eruption.
Nonvolcanic earthquakes result from fault movement, not magma.
The nonvolcanic mountains were shaped by ancient collisions of continental plates.
