Learn MoreLabradorite, a plagioclase feldspar, has the chemical formula ((Ca, Na)(Al, Si)4O 8) while orthoclase, a potassium feldspar, has the chemical formula KAlSi 3 O 8. The minerals in the feldspar group are individual minerals that just happen to all be incredibly similar—so similar, that people lump them together.
Learn MoreMicrocline is an extremely common mineral, and only remarkable occurrences are mentioned here. Excellent crystals associated with Aegirine come from Mount Malosa, Malawi. Other worldwide sources of large Microcline crystals are the Erongo Mountains, Namibia; Papachacra, Catamarca, Argentina; the Shigar Valley, Skardu, Pakistan.
Learn MoreThe mineral composition of most feldspars can be expressed in the ternary form including albite, orthoclase, and anorthite. The minerals of which composition is based primarily on the solid solution range between albrite and anorthite is what is known as the plagioclase feldspars while those between albrite and orthoclase or mono line are what is collectively known as alkali
Learn MoreOrthoclase. An important rock-forming mineral, orthoclase is the potassium-bearing end member of the potassium sodium feldspar solid-solution series. It is a major component of granite its pink crystals give granite its typical color. Crystalline orthoclase can also be white, colorless, cream, pale yellow, or brownish red.
Learn MorePotassium(K) Sodium(Na) aluminosilicate = alkali feldspar. Examples include moonstone, amazonite, orthoclase. Other terms used for potassium-rich feldspars include: sanidine, orthoclase, microcline Albite is a term used for sodium-rich feldspar. Sodium(Na) Calcium(Ca) aluminosilicate = plagioclase. One example is the mineral labradorite
Learn MoreOrthoclase 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 x-ray analysis.
Learn MoreThe three different but closely related species of alkali feldspar are sanidine, orthoclase, and microcline. The differences among these feldspars result from details of their atomic structures, principally the different ways in which aluminum is distributed, or ordered, in the aluminosilicate frameworks of each.

Learn MoreFeldspar 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).
Learn MoreFeldspars are found in pegmatite rocks usually of the granite type which can be considered as a mixture of feldspar minerals together with quartz and mica [9]. The feldspar mining operation uses the conventional open-mining system whereby the overburden is removed by bulldozer or backhoes followed by drilling and blasting.
