5.2 Chemical Weathering – Physical Geology

The hydrolysis of feldspar can be written like this: CaAl 2 Si 2 O 8 + H 2 CO 3 + ½O 2 —-> Al 2 Si 2 O 5 (OH) 4 + Ca 2+ + CO 3 2-plagioclase + carbonic acid —-> kaolinite + dissolved calcium + carbonate ions. This reaction shows calcium plagioclase feldspar, but similar reactions could also be written for sodium or potassium feldspars.

Feldspar - Chemical composition | Britannica

Feldspar - Feldspar - Chemical composition: All the rock-forming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually designated Or in discussions involving their end-member ...

5.2 Chemical Weathering – Physical Geology

Sep 01, 2015· 5.2 Chemical Weathering. Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals, like quartz, are virtually unaffected by chemical weathering, while ...

Reading: Characteristics of Sedimentary Rocks | Geology

Although feldspar is a fairly hard mineral, it does cleave (split apart) and is chemically reactive, especially in the presence of water. The most abundant product of chemical reaction of feldspar and water is clay minerals. During the erosion-to-deposition process, clastic sediments lose feldspar and gain a larger proportion of clay.

Weathering & Clay Minerals - Tulane University

Thus, rocks rich in feldspar commonly weather to kaolinite. In order to form, ions like Na, K, Ca, Mg, and Fe must first be leached away by the weathering or alteration process. This leaching is favored by acidic conditions (low pH). Granitic rocks, because they are rich in feldspar, are a common source for kaolinite.
