[1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties.Feldspars in Weathering | SpringerLink,Abstract. Feldspar weathering occurs via dissolution of all components into solution, with the subsequent precipitation of secondary minerals from solution, and it is the feldspars dissolution rate which controls the overall rate of feldspar weathering.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.
