Definitions:

Fold and Thrust Belt

A region in the earth's crust where the rocks have been deformed by horizontal compression, leading to the formation of folds and thrust faults.

Anticlines

Upwardly convex folds in rock layers, typically formed through compression within the Earth's crust.

Synclines

Downward-curving folds in sedimentary strata, opposite of anticlines, which can also be indicators of oil and gas deposits.

Cleavage

In geology, the tendency of crystalline materials to split along definite crystallographic structural planes, creating flat, shiny surfaces.
