What Are the Products of the Chemical Weathering of Feldspar?
Apr 25, 2017 In terms of its chemical composition, feldspar is an aluminosilicate. Plagioclase is a sodium or calcium aluminosilicate, occuring widely in rocks as free crystals. Under a polarising microscope, plagioclase crystals are shown to be triclinic in nature. Orthoclase feldspar is a silicate of aluminium and potassium and occurs homogenised in rocks
5.2 Chemical Weathering Physical Geology
Sep 01, 2015 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 others, like feldspar, are
Chemical Composition Plagioclase Feldspar
Composition of Plagioclase is described in terms of Anorthite with An + Ab = 100. The solid solution equilibrium equation can be written as Na +1 Si +4 <=> Ca +2 Al +3 (Nesse 2012). Plagioclase nomenclature is based on the percent of anorthite in the sample. The possible forms of Plagioclase are listed below. Albite An0 An10.

Sodium feldspar chemical formula or albite formula- NaAlSi₃O₈. Calcium feldspar chemical formula- CaAl₂Si₂O₈. Bowen's Reaction Series. Solid solutions between K-feldspar and albite are called alkali feldspar. Solid solutions between albite and anorthite are called plagioclase, or, more properly, plagioclase feldspar.

Constructing a phase diagram for feldspar weathering Below is a list of aluminosilicate minerals formed from weathering of K-feldspar. Note that many of the minerals formed in the real-world weathering environment have complicated structures and compositions. The phases listed below are simple analogs for these minerals.
