Calcite is a rock-forming mineral with a chemical formula of CaCO 3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere.

Albite Feldspar: Composition, Structure and Associated Minerals: Albite a widely distributed and important rock-making mineral. It occurs in all classes of rocks, but particularly in those of igneous origin, such as granites, syenites, porphyries arid felsite lavas. Found commonly, also, in pegmatite veins.

What is Plagioclase? "Plagioclase" is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and anorthite.
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 upon feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8).
The Himalaya Mine, in nearby Mesa Grande, is also a world-famous Elbaite producer. Other important Southern California localities in San Diego Co. include the Little Three Mine, Ramona; and the Cryo-Genie Mine, Warner Springs. On the East Coast of the U.S., in New England, are some of the classic and famous Tourmaline quarries.
Albite is a very common mineral, and is an important rock-forming mineral. It takes a longer time for Albite to crystallize than the other feldspars. This enables Albite to form in large and well crystallized examples. Albite is also a common accessory mineral to many rare and unusual minerals.

Mar 27, 2015· Mining for tourmaline began in the 1950s when Jose Neves and his brother Antonio De Assis Neves started what is now the Cruzeiro tourmaline mine. The brothers had been mining mica in the area and taking it to Governador Valadares to sell. They also bought and sold the production of …
Albite, common feldspar mineral, a sodium aluminosilicate (NaAlSi 3 O 8) that occurs most widely in pegmatites and felsic igneous rocks such as granites.It may also be found in low-grade metamorphic rocks and as authigenic albite in certain sedimentary varieties. Albite usually forms brittle, glassy crystals that may be colourless, white, yellow, pink, green, or black.
Albite is the last of the feldspars to crystallize from molten rock. The process of crystallization from a molten rock body serves to isolate rarer elements in the last stages of crystallization and therefore produces rare mineral species. Thus albite is often found with some lovely rare and beautiful minerals.
Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate, Li Al(Si O 3) 2, and is a source of lithium.It occurs as colorless to yellowish, purplish, or lilac kunzite (see below), yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size.Single crystals of 14.3 m (47 ft) in size are reported from the Black Hills of South Dakota, United States.
