Morphology
epithermal = thermal (semi-transparent) = epi + thermal
Built from the combining form 'epi-' (a technical Greek-derived prefix) plus 'thermal'; the formation is regular but the precise geological nuance ('near-surface, moderate temperatures') is domain-specific and may not be obvious to general learners.
Etymology
Epithermal comes from the Greek parts epi- meaning 'near' or 'upon' and therm- meaning 'heat', so it literally says 'near heat'. That's why geologists call mineral veins and deposits made by hot fluids close to the Earth's surface epithermal.
