Feldspars in Weathering SpringerLink

网页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. The rate of feldspar dissolution is controlled by the kinetics of surface reactions at the mineral

网页Silicate minerals other than feldspar can undergo hydrolysis, but with different end results. For example, pyroxene can be converted to the clay minerals chlorite or smectite. Olivine can be converted to the clay mineral serpentine. Hydration. Hydration reactions involve water being added to the chemical structure of a mineral.

10.2 Chemical Weathering Environmental Geology

网页There are two main types of chemical weathering. On the one hand, some minerals become altered to other minerals. For example, feldspar is altered—by hydrolysis—to clay minerals. On the other hand, some minerals dissolve completely, and their components go into solution. An example is calcite (CaCO 3) which is soluble in acidic solutions.
