Morphology

silicious = silica (transparent) = silic + ious

The adjective is formed by a regular adjectival suffix (-ious) from 'silica', so its meaning is directly derivable from the noun.

Etymology

Silicious comes from the Latin root silic-, which meant 'flint' or 'hard stone', and is the same root as silica and silicon. So, to call a rock silicious is to say it is like 'flint' or is made mostly of silica, the material in sand and glass.
