Morphology

dacitic = dacite (transparent) = dacite + ic

Formed regularly from the noun 'dacite' with the productive adjectival suffix '-ic', so the relation is morphologically clear though the base is a specialized geological term.

Etymology

Dacitic comes from dacite, which was named after Dacia, an old region of Romania where this rock was first found. So, dacitic means 'from Dacia' or 'like that volcanic rock', which is why it describes a kind of volcanic rock.
