The provenance , or source area from which the sediment is derived, is the main control on sediment composition . The tectonic setting also has some influence on the accumulation of sediment and hence, its provenance. For example, if only quartz sandstone is exposed in the source area, the sediments derived from that source region will be quartz-rich.
Flat areas serve as local base levels, places where potential energy is at a minimum.
Here, the degree to which downward erosion and disintegration of a landscape will occur is reduced. Mixing of rocks from different sources. Back to Siliciclastics Rocks Home 5,381 accesses since August 8, 1997.
