Weathering and Global Denudation

A negative correlation between sediment yield and weathering history, as measured by the chemical alteration (CIA) of the suspended sediment, is observed for many of the world's major rivers and other regions of denudation. The weathering history is a first-order control on the sediment yield of such areas, termed equilibrium denudation regions. For other areas, data scatter with either apparent increases or decreases of sediment yield for given...
