Morphology
depositional = deposition (semi-transparent) = deposit + ion + al
The adjective is a regular formation from 'deposition', but the geological sense is technical and may not be obvious to an average learner.
Etymology
Depositional comes from the same root as deposit, made of Latin parts de- 'down' and ponere 'to put'. In geology the earth 'puts down' sand, mud, and rock in layers, so depositional describes places or processes where material is 'put down'.
