Mineral chemical weathering
WebProducts of weathering usually clay minerals, are commonly characterized through mineralogical, ... and minor REE leaching out by lessivage. The degree of chemical weathering depends on the decaying of four base weathering elements (Mg, Ca, Na, K) in minerals and is relatively less dependent on the slow leaching of silica.
