Feldspar

Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust 1. Feldspars occur in most igneous and metamorphic rocks. They are less common in sedimentary rocks as they tend to break down to clay minerals in the weathering environment.

Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust. Feldspars include three compositional endmembers: K-feldspar (KAlSi 3 O 8 ), albite (NaAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8) Fig.1. Alkali feldspars are ...

10.2: Chemical Weathering

This reaction shows calcium plagioclase feldspar, but similar reactions could also be written for sodium or potassium feldspars. In this case we end up with the mineral kaolinite along with calcium and carbonate ions in solution. Those ions can eventually combine to form the mineral calcite, and that will probably happen in the …
