Describe a clastic wedge. How can a clastic wedge be used as evidence for an orogeny?
A clastic wedge is an extensive accumulation of mostly detrital sediments deposited adjacent to an uplifted area. The wedge is thickest nearest the uplift and thins with distance from the uplift. These sediments eventually grade into carbonate cratonic facies. The existence of the wedge indicates that there was once a highland because of the thick sediments at one end and thinned sediments at the other. A highland indicates that there was once an orogeny.
