The geologist described the orogenous processes that uplifted the plateau during the Cenozoic.

Geologists mapped the ancient orogens to understand past continental collisions.

The geologist collected samples of orogen from the mountain range to study the effects of ancient collisions.

The basin was orogenically uplifted during the Cenozoic, altering its drainage patterns.

The orogenic belt preserves a complex history of continental collision and metamorphism.

The orogenous zone along the continental margin produced dramatic folds and thrust faults over millions of years.

The couple discussed boundaries around their orogenous zones before becoming intimate.
