The magmatics in the igneous sequence provided crucial clues about the region's volcanic history.

The graduate seminar on magmatics attracted students from geology and planetary science.

The new mineral layer formed magmatically beneath the volcano, altering the surrounding rock's composition.

Geologists studied the magmatic intrusions that altered the surrounding rock.

A geologist examined a magmatic and determined it had crystallized slowly deep underground.

The geologist studied magmatism beneath the mountain to understand volcanic hazards.
