Silicates hydrolysis


Silicates hydrolysis is one of the most important rock destruction chemical processes due to the abundance of rock silicates and is due to the reaction of water with aluminized silicates, present as feldspar and feldspar. Processomodifica wikitesto

In contact with rock, water dissociates into H and OH ions, and this process produces sodium, potassium, magnesium and calcium hydroxides as aluminum, silicon and iron hydroxides are suspended.

The crystalline lattice inside is flattened, falling apart in fragments of very small size, called colloidal. Effectively modifies wikitesto

The process causes disintegration in many rocks, especially endogenous and metamorphic. Decomposed rock becomes friable ("rock") and assumes a particular yellowish or reddish coloring, causing the oxygenation of the iron-containing compounds. Also, in the pebbles a delicate superficial crust encloses a less altered inner core.
