Morphology

microgranitoid = granitoid (semi-transparent) = micro + granit + oid

The prefix micro- clearly contributes the idea of fine grain or small size, but the geological base granitoid is specialized, so the meaning is only partly transparent.

Etymology

Microgranitoid combines micro- ('small'), granite (a hard rock) and -oid ('like'). As a noun, a microgranitoid is a rock that is 'small-grained and granite-like', made of minerals similar to granite.
