Morphology
pyrogenous = pyro + gen + ous
The word is built from classical elements meaning roughly 'fire/heat' and 'produced', so the geological sense is partly inferable, but it remains a technical term rather than a fully transparent everyday formation.
Etymology
Pyrogenous comes from the root pyro- meaning 'fire' and the part -genous meaning 'produced', and you can see pyro- in words like pyrotechnics. So pyrogenous means 'made by fire', which is why geologists use it for rocks and substances formed under very high heat.
