Morphology
microgranitoid = granitoid (semi-transparent) = micro + granit + oid
The prefix micro- is clear, but the base granitoid is a specialized geological term, so the whole form is only partly predictable for general learners.
Etymology
Microgranitoid combines micro- ('small'), granite (a hard rock) and -oid ('like'). It means 'small-grained and granite-like', so as an adjective it describes a rock or texture that looks like granite but with very small grains.
