The 12 Different Types Of Feldspar (With High-Quality Photos)
Feldspar forms in a variety of geological settings, from deep within the Earth's crust to the cooling lava of a volcano. This diversity in formation environments is a big reason why there are so many different types of feldspar. The range of colors seen in feldspar is due to trace elements and impurities that get mixed in during its formation.

Feldspar
Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8).

Feldspar Distinctions, Characteristics, and Identification
The basic feldspar recipe is X(Al,Si) 4 O 8, where X stands for Na, K, or Ca. The exact composition of the various feldspar minerals depends on what elements balance the oxygen, which has two bonds to fill (remember H 2 O?). Silicon makes four chemical bonds with oxygen; that is, it's tetravalent.

Feldspar
Sodium feldspar (NaAlSi 3 O 8) exhibits a lower viscosity than potassium feldspar when melted at a given temperature. This enables vitrification at lower temperatures but carries the risk of increased deformation. Calcium feldspar (CaAl 2 Si 2 O 8) has an extremely narrow firing range. Figure 2 shows the mineralogy of some of Uganda's ...

The mineralogy of sandstones: feldspar grains
Feldspars are also common in metamorphic rocks. As such, feldspar is an important (usually subordinate) component of most terrigenous clastics, reflected in its inclusion in QFL classification schemes. The two major groups of feldspar are potassium feldspars and plagioclases. All have low relief in plain polarized light (similar to quartz).
