KFeldspar and Plagioclase Feldspar

Feldspars have two cleavage planes that intersect at 90°. Fragments of pure feldspar crystals thus tend to form rectangular blocks with irregular ends. Feldspars have vitreous lusters and occur in opaque shades of white to gray to pink to very dark gray.

Feldspars |

feldspars The most important group of rockforming silicate minerals, including the alkali feldspars KAlSi 3 O 8 to NaAlSi 3 O 8 (Kfeldspar to albite) and the plagioclase feldspars NaAlSi 3 O 8 to CaAl 2 Si 2 O 8 (albite to anorthite).

Orthoclase: The mineral Orthoclase information and pictures

Orthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is polymorphous with the minerals Microcline and three minerals form the Potassium Feldspar are almost identical in physical properties, and it is sometimes impossible to distinguish one another without xray analysis.

Granite: Igneous Rock Pictures, Definition More

Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content. Applying this definition requires the mineral identification and quantification abilities of a competent geologist.

Feldspar Uses |

Feldspar Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldsparrich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Feldspar Wikipedia

Feldspars (K Al Si 3 O 8 – Na Al Si 3 O 8 – Ca Al 2 Si 2 O 8) are a group of rockforming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see ...

ORTHOCLASE (Potasium Aluminum Silicate)

Orthoclase is a polymorph of other minerals that share the same chemistry, but have different crystal structures. If positive identification between these minerals can not be made by field methods, then the specimen may simply be referred to as a potassium feldspar or Kspar .

Albite: The plagioclase feldspar mineral Albite ...

Albite belongs to the Plagioclase Feldspar group, an isomorphous solid solution is one end member, containing sodium and no calcium. The other end member, Anorthite, contains calcium and no intermediary members are Oligoclase, Andesine, Labradorite, and and Andesine are considered by some to be a variety of Albite rather then a separate mineral.
