The feldspars are the most abundant and widespread rock-forming minerals and are the main constituents of major rock types such as granites and gabbros. They are aluminosilicates and undergo complex reactions upon cooling from melts or following high-temperature metamorphism as a result of the ordering of Si and Al.
Feldspar can be characterised by: Relatively high Mohs hardness of 6 Low electrical conductivity Easy to wet High inertness in various media. And, depending on the grade: Low content of lamellar mica (Unispar FF) Low fine crystalline silica fraction (no labelling) (Unispar PG (W)) Whiteness (Unispar PG W).

Compositions of Feldspar Group Minerals This group of minerals includes tectosilicates. Compositions of foremost elements in commonplace feldspars may be expressed in terms of 3 endmembers: potassium feldspar (K-spar) endmember KAlSi3O8, albite endmember NaAlSi3O8, anorthite endmember CaAl2Si2O8.
The feldspars are complex aluminosilicate minerals containing K, Na, and Ca, with some rarer types rich in Ba. The structures of these species are very similar. However, most feldspars crystallize from a melt in igneous rocks. The …
The feldspar mineral group is divided into two further groups: potassium feldspar and plagioclase. Potassium feldspars are characterised by their high sodium and potassium content, while plagioclase is extremely rich in calcium …
There are just about 26 different minerals that fall into this classification, and these are grouped into two subgroups. The first is plagioclase feldspar. The minerals in this group contain calcium and sodium, and are a combination of albite and anorthite. Some of the better known minerals in this category are labradorite, albite, and andesine.

Feldspars ( K Al Si 3 O 8 - Na Al Si 3 O 8 - Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals which make up as much as 60% of the Earth 's crust. [1] Feldspars crystallize from Magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types of Metamorphic rock.

The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8). Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements.
Potash and soda feldspar occur a s essential constituents of granite, syenite and gneisses. However, workable deposits are found in pegmatite venis constituting mainly of feldspar, quartz-feldspar veins and also occur with mica pegmatites. Feldspar is of widespread occurence and is mined in almost all countries. Feldspar are aluminosilicates.
