How does Kaolinite form?

Answer 1

Naturally formed acids can weather rocks. When water reacts with carbon dioxcide in the air or soil, a weak acid, called Carbonic acid, forms. Carbonic acid reacts wih minerals such as calcite, which is the main mineral that makes up limestone. This reaction causes he calcite to dissolve. Over many thousands of years, carbonic acid has weathered so much limestone that caves have formed.

Chemical weathering also occurs when naturally formed acids come in contact with other rocks. Over a long period of time, the mineral feldspar, which is found in granit, some types of sandstone, and other rocks, is broken down into clay mineral called KAILINITE. Kaolinite clay is common in some soils. Clay is an end product of weathering.
