Morphology

dolomite = Dolomieu (opaque) = dolom + ite

Formed from the proper name 'Dolomieu' plus the mineral-forming suffix '-ite'; the stem is an eponym and does not transparently convey meaning to learners.

Etymology

Dolomite as a rock also takes its name from the geologist Dolomieu, who described the famous rock layers in the Dolomite range. Like other stone names ending in -ite, dolomite means a type of rock similar to limestone that contains a lot of magnesium, which is why it is important in construction and industry.
