4 Types and Examples of Chemical Weathering

Oct 29, 2019 · Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. The clay weakens the rock, making it more likely to break.

Feldspar

Johnson and Rossman (2004) calculated that feldspar micropores contain about the same amount of water as all the conventional hydrated minerals in the upper crust combined. Feldspar color is due partly to tiny mineral inclusions in the pores, hematite in pink and red feldspars and Fe–Ti oxides in gray and white feldspars.
