Stratigraphy, magnetic susceptibility, and mineralogy of loess-paleosol sequences in southwestern Illinois and eastern Missouri
… of source area shifts caused by Mississippi River diversion at about 20.5 ka. MS zones are less pronounced along the Mississippi Valley south of St. Louis. Alteration of magnetite in gleyed loess can occur but is not thought to cause MS zones observed because minor increases in illite and …

The influence of earth surface movements and human activities on the river Karun in lowland south-west Iran
… movements are a primary external control on river system dynamics and evolution. It has often been observed that when responding to Earth surface motion driven by surface expression of folds, major rivers incise across young, active folds near their structural culminations and divert around …
