  • Weathering of Granitic Muscovite to Kaolinite and

    Abstract. Weathered perthite and mixed muscovite kaolinite from a kaolinitic granite at Trial Hill in east Queensland and kaolinized sericitic alteration from a granite from the Ardlethan Tin Mine of New South Wales were examined by optical, scanning electron (SEM), and transmission electron microscopy (TEM) to determine the alteration process of muscovite to kaolinite and kaolinite

    Kaolinite. Kaolinite is a layered silicate clay mineral which forms from the chemical weathering of feldspar or other aluminum silicate minerals. It is usually white, with occasionally a red color impurity due to iron oxide, or blue or brown from other minerals.

  • Kaolinite: The clay mineral kaolinite information and pictures

    Kaolinite also has a very similar chemical formula to Serpentine, and is sometimes considered a member of the Serpentine group. Kaolinite is the most common clay mineral, and entire clay deposits can be composed of this mineral. There are many commercial Kaolinite mines where this mineral is mined in large volumes for its various industrial uses.

    Oct 20, 2019· Besides kaolinite, kaolin group minerals also include dickite, nacrite, and halloysite. Although they are the product of aqueous weathering or hydrothermal alteration of micas and feldspars at low pH conditions, only kaolinite and halloysite are found and often coexist in modern soils and sediments (Cygan and Tazaki, 2014).

  • Identification of weathering and hydrothermal alteration

    A major problem in ore prospecting on granitic terrains is to make a distinction between clay mineral assemblages due to weathering and those due to hydrothermal alteration. The most outstanding features of these two types of transformation are : 1. Potassic beidellite is typical of hydrothermal alteration. 2. Low iron content mineral assemblages in the presence of large amounts of kao linite
