Belts of ________ in layered sedimentary rocks are evidence for horizontal compression and shortening.

Question

Quizplus · Accepted Answer

Belts of tight folds in layered sedimentary rocks indicate that the rocks were subjected to horizontal compression and shortening, as the original layers were curved and deformed into folded structures. Normal faults are characterized by the displacement of rock layers along a vertical plane, while strike-slip faults involve horizontal movement along a fault zone. Horsts and grabens are features found in areas of crustal stretching, and involve the formation of uplifted blocks of rock (horsts) and down-dropped blocks of rock (grabens). None of these features are typically associated with horizontal compression and shortening.
