Schematic model of fluvial systems both before and after the development of land plants: before the Devonian period, minimal land plants, rapid channel migration and river systems dominated by braided rivers led to rapid sediment transfer, minimal development of mud-sized particles and minor deposition of mudrocks along continental margins; in contrast, after the Devonian, the expansion of vascular land plants led to the development of meandering rivers and the dramatic slowing of sediment transfer to marine environments; the red dashed line represents a generalized sediment transport path that is more sinuous post-Devonian and less sinuous pre-Devonian; these diametric depositional systems influenced the isotopic composition of sediment available for reworking and melting in magmatic systems along destructive plate boundaries.
