Morphology
The meaning 'a major division of geological time' is transparently derived from combining 'geological' (relating to Earth's physical structure and processes) with 'era' (a large timespan). The adjective+noun composition is literal and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.
Etymology
Geological era comes from the idea of reading the Earth like a very slow book: geological points to the Earth's rocks and era is like a long 'chapter' in that book. So a geological era means a very long span of Earth’s history when certain plants, animals, and events were common.
