Feldspar mineral family Gemstone's Information
The feldspar group is divided into two distinct varietis: (1) the orthoclase or alkali which is rich in potassium and sodium (alkali elements), moonstone, orthoclase, and amazonite are the main members of this group; (2) the plagioclase feldspars (also known as sodalime feldspars) that constitute an isomorphous series between albite, the sodium aluminium silicate, NaAlSi3O8, and anorthite, the .

What Is Granite And How Is It Formed? Geology In
Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock. Generally, the slower the molten rock cooled, the larger it's mineral crystals with KFeldspar megacrysts forming in special circumstances greater than 5cm.

Feldspar | IMA Europe
Feldspar. Amongst the numerous rocks in which they are present, feldspars are particularly abundant in igneous rocks like granite, which contains up to 50 or 70% of alkaline feldspar. Granite is however rarely used for its feldspatic content. Rather a whole range of rocks geologically connected to granite is used.

Physical Properties of Minerals Tulane University
We will first discuss each of the physical properties that can be used, then develop a methodical approach to the identification of minerals using these physical properties. Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste.
