Albite is a very common mineral, and is an important rockforming 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. Mineral Gallery from New Hampshire in Online ...

Albite is a rock forming mineral in pegmatites and the characteristic, interlocking blady variety known as cleavelandite is a sign of the presence of possible pockets. Albite also forms very fine crystals in vuggy alkali foidic syenites. In pegmatites, albite forms crystals up to about 8cm in pegmatite which can sometimes be gemmy.

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 is a layered silicate mineral, with one tetredral sheet of silica (SiO 4) linked through oxygen atoms to one octedral sheet of alumina (AlO 6) octedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.
Augite. Augite is a rockforming mineral of the pyroxene group commonly found within igneous and metamorphic rocks. Because its chemical structure is highly variable, augite might be considered by some to be its own group of minerals rather than an individual mineral.
Albite, common feldspar mineral, a sodium aluminosilicate (NaAlSi 3 O 8) that occurs most widely in pegmatites and felsic igneous rocks such as may also be found in lowgrade 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 feldspar is an important ingredient in some building and ornamental stones, notably granites, some of the finest of which owe their beauty to feldspar crystals. Albite from the pegmatite veins of southeastern Pennsylvania and northeastern Maryland has been mined .
The width at the mine between the serpentine walls is about 150 feet and at a distance of 150 feet east of the mine it is only about 90 feet; about 80 feet farther east at the apex it is over 100 feet. This schist inclusion has been described by Kalph Arnold as 150 feet .
The matrix is albite and quartz with minor silver sheets of mica. The schorl crystal on the far right is complete and terminated, and partially hidden by albite. Part crystals and lumps of schorl litter the rest of the specimen. All specimens from the mine in the early 1970''s were sold as schorl. There has been debate over the years whether it ...
Albite is a very common mineral, and is an important rockforming 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.
Search for moonstone in areas where a high concentration of albite. Albite is a feldspar variety, containing moonstone in a high quantity. Albite minerals also contain some of the rarest forms of moonstone. These locations can be found around the country in areas such as Southern California, Maine, North Carolina, and ia.
"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.
In Developments in Geochemistry, 2007. pH dependence of the dissolution kinetics of feldspars. Albite. Figure shows that the dissolution rate of albite is strongly dependent upon pH and temperature. At all temperatures, from 5 to 300°C, the dissolution rate is at a minimum in the neutral range and increases in both the acidic and basicpH intervals.
Albite and Clevelandite mineral information page at mineralminers: your online link for factual scientific and mineralogical information concerning natural albite feldspar and clevelandite, which are a variety of sodium rich plagioclase feldspar, with information on albite mining locations as well as background info on albite physical ...
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.
The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana''s System of Mineralogy lists the intermediary members as individual minerals, whereas ...
Feldspar is mined from large granite bodies (called plutons by geologists), from pegmatites (formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vaporrich pockets that allow the growth of extremely large crystals), and from sands composed mostly of feldspar. ...
