How Are the Minerals Biotite Mica and Muscovite Mica Different
Clay minerals are classified into three groups on the features of layer type as follows Barton 2002. Aluminum hydroxides boehmite diaspore gibbsite are economically important as aluminum ore minerals.

. Generally these structures are formed in fine grained rocks composed of minerals affected by. The degree of deformation and metamorphism along with rock type determines the kind of cleavage feature that develops. Interactive guide to hundreds of rocks and minerals.
This group includes mainly Mica illite clay mineral which is a secondary form of mineral precipitate. 2 the silicate unit layer of another type consists of one octahedral layer which is sandwiched. Cleavage in structural geology and petrology describes a type of planar rock feature that develops as a result of deformation and metamorphism.
Muscovite also known as common mica isinglass or potash mica is a hydrated phyllosilicate mineral of aluminium and potassium with formula K Al 2 AlSi 3 O 10FOH 2 or 2 Al 2 O 3 3 SiO 2 6 H 2 OIt has a highly perfect basal cleavage yielding remarkably thin laminae sheets which are often highly elasticSheets of muscovite 5 meters 3 meters 165 feet 10 feet. Feldspars are very common minerals in the crust more than half 51 of. This group is an example of a phyllosilicate or layered alumino-silicate.
1 11 clays where each layer consists of one silica tetrahedral sheet that is joined with an aluminum octahedral layer eg kaolinite and serpentine. We are constantly working on expanding this list. Muscovite and biotite are also found in the clay fractions which are also called fine grained Mica.
Non-expanding clay minerals. Very widespread in silicate minerals feldspar clay minerals mica.
