Buttress Unconformity, northern Arizona

April 30, 2017/in Arizona, Unconformities/by Marli Miller

Buttress Unconformity, northern Arizona. In buttress unconformities, the younger material
is deposited against the older material, resulting in the apparent truncation of the younger rock. On
closer inspection, however, one can see erosional features along the contact to indicate its depositional
origin. (ID SrU-25)
