Oceanic-continental plate orogenesis can be recognized in the geological record by a(n):
A)accretionary wedge containing ophiolites.
B)landward belt of volcanoes and batholiths.
C)inland zone of block faults.
D)accretionary wedge containing ophiolites AND landward belt of volcanoes and batholiths.
E)all of these.

Question

Quizplus · Accepted Answer

Oceanic-continental plate orogenesis results in the subduction of oceanic lithosphere beneath continental lithosphere, which creates an accretionary wedge containing ophiolite fragments as well as a landward belt of volcanoes and batholiths. Additionally, the inland zone may experience block faulting. Therefore, option D, which includes both the accretionary wedge and the landward belt, is the best choice.
