Weathering and Mineralogical Alteration of Granitic Rocks .

The major primary minerals identified in the weathering crust of granitic rocks are quartz, muscovite, feldspar and biotite. The dominant secondary minerals are kaolinite, montmorillonite and illite. Quartz is found in all the sequences of weathering crust for its poor susceptibility to chemical weathering.

Kaolinite - Wikipedia

Kaolinite - Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

May 01, 2015 · Ø Intermediate argillic alteration affects mainly plagioclase feldspars and is characterized by the formation of clay minerals kaolinite and the smectite group (mainly montmorillonite). It typically forms below about 250°C by H+ metasomatism and occurs on the fringes of porphyry systems.

Kaolin | IMA Europe

Kaolinite is a mineral belonging to the group of aluminosilicates. It is commonly referred to as "China Clay" because it was first discovered at Kao-Lin, in China. The term kaolin is used to describe a group of relatively common clay minerals dominated by kaolinite and derived primarily from the alteration of alkali feldspar and micas.

Mineral alteration - Wikipedia

Mineral alteration - Wikipedia

Mineral alteration is distinctly different than the rock alteration process metamorphism. It also differs from weathering. However, these processes assist in mineral alteration. Some minerals are members of a solid solution series and are samples of a range of compositional changes in a continuum, and thus are not 'mineral alteration' products.
