Morphology

chemopause = pause (semi-transparent) = chemo + pause + chemo

The parts ('chemo-' and 'pause') are recognisable, but the use of '-pause' as a technical boundary term and the combining form 'chemo-' make the meaning somewhat specialised for average learners.

Etymology

The word chemopause comes from chemo- meaning 'chemical', as in chemistry, and pause meaning 'stop' or 'break'. So a chemopause is the place in a planet's air where the chemistry seems to 'pause' and change suddenly.
