Orthoclase: The mineral Orthoclase information and picturesOrthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is polymorphous with the minerals Microcline and Sanidine. These three minerals form the Potassium Feldspar group. They are almost identical in physical properties, and it is sometimes impossible to distinguish one another.orthoclase feldspar orthoclase,Orthoclase: Pink granite, Mohs hardness and moonstoneOrthoclase is the feldspar mineral of pink granite, the #6 mineral of the Mohs hardness scale, and one of the two minerals that comprise Moonstone.

ORTHOCLASE (Potasium Aluminum Silicate) - Amethyst Galleries

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 K-spar. Plagioclase feldspars lack potassium, are light.

Orthoclase - Wikipedia

Orthoclase, or orthoclase feldspar is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar. The gem known as moonstone (see.

Orthoclase feldspar is a potassium aluminum silicate, and is commonly called "potassium feldspar" or simply "K-spar," given that the chemical symbol for potassium is "K." Orthoclase is common in igneous rocks such as granite, granodiorite and syenite, as well as in crack-filling igneous vein material (pegmatite). Orthoclase.

Feldspar

Feldspar is a name given to a class of aluminum-containing silicates which are sometimes called light silicates or "nonferromagnesian silicates" since they don't contain iron or magnesium. The feldspars include orthoclase (KAlSi3O8) and plagioclase ((Ca,Na)AlSi3O8). Note that the plagioclase differs from the orthoclase in.

One of these elements is usually dominant, but most of the feldspars contain all 3 in varying amounts. It is the proportions of these 3 elements which help determine which specific feldspar is formed.
