Morphology

rhyolitic = rhyolite (transparent) = rhyolite + ic

Clear adjectival formation from the noun 'rhyolite' meaning 'relating to rhyolite'.

Etymology

Rhyolitic comes from the rock name rhyolite, which was built from a Greek root rhy- meaning 'flow' and the ending -lite meaning 'stone', like in meteorite. So rhyolitic describes a light-colored volcanic rock made from flowing lava, which is why geologists use the word for silica-rich volcanic stones.
