Morphology
obduction = obduct (semi-transparent) = obduct + ion
Morphologically clear as 'obduct' + '-ion', but the geological sense is technical and not easily inferred by general learners.
Etymology
Obduction comes from Latin parts ob- 'over' and ducere 'to lead', the same root as conduct. In geology, an obduction is when ocean rock is pushed 'over' the edge of a continent, so the idea of 'leading over' explains the process.
