A sodium feldspar with twinning striations is called albite, while a calcium feldspar with twinning striations is called anorthite.
Common minerals found in pegmatites from Transmountain Road may include quartz, feldspar (such as albite or orthoclase), mica (like muscovite or biotite), and tourmaline. Additionally, minerals like beryl and tantalite can also be present in pegmatites in this region.
There are broadly three main types of feldspars: calcium, sodium and potassium. They have the following general chemical formulas:KAlSi3O8 - NaAlSi3O8 - CaAl2Si2O8The endmember mineral states are known as K-Feldspar, Albite and Anorthite which are the potassium, sodium and calcium feldspars respectively.There can be a mix of calcium and sodium (more correctly termed solid solutions) in Feldspars between Albite and Anorthite which are known generally as Plagioclase feldspars.For more information please see the related question
Moonstone belongs to the feldspar group and has a monoclinic crystal structure. It typically exhibits a prismatic, tabular, or blocky appearance, often with fine striations. Moonstone's crystal structure is characterized by its layers of alternating orthoclase and albite feldspar minerals, which create the mesmerizing adularescence or "moon-like" sheen when light reflects off its surface.
Alkali feldspar has the general formula (K,Na)AlSi3O8, but varies in crystal structure depending on the temperature it formed at. The formula actually is a blend ranging from all sodium (albite) to all potassium (microcline), but albite is also one endpoint in the plagioclase series so we classify albite there. This mineral is often called potassium feldspar or K-feldspar, because by definition potassium always exceeds sodium in its formula. It comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400° C. Orthoclase is stable above 500° C and sanidine is stable above 900° C. In a plutonic rock that cooled very slowly to yield large mineral grains, it's safe to assume that this is microcline. In the field, workers generally just write down "K-spar" and leave it at that until they can get to the laboratory. Alkali feldspar is generally white, buff or reddish and is not transparent, nor does it show the striations of plagioclase. A green feldspar is always microcline, the variety called amazonite.
Yes, albite is a common mineral found in many states from California to Maine.
Albite is a salt: a sodium-aluminium silicate, NaAlSi3O8.
Lime feldspar is a synonym for anorthite (CaAl2Si2O8) not for albite (NaAlSi3O8).
Albite is a common feldspar mineral typically found in granitic and pegmatitic rocks. It often occurs in metamorphic rocks and can also be found in sedimentary deposits. Locations with significant albite deposits include areas like the United States (especially in Maine and California), Canada, and parts of Europe, including Norway and Finland. It is also associated with other minerals in hydrothermal veins.
No, albite is not magnetic. It is a sodium-rich feldspar mineral that typically does not exhibit any magnetic properties. While some minerals can be magnetic due to the presence of iron or other magnetic elements, albite does not contain these in significant amounts. Therefore, it does not respond to magnetic fields.
Albitization is the conversion of a mineral into albite, a form of feldspar.
Alaskite is a type of granite composed mainly of quartz and feldspar. It is not used for anything in particular unless it contains economic minerals that can be mined, like uranium (as in the Rossing Mine, Namibia). Otherwise it could be used as a construction material if a suitable quarry of it was available.

Yes! It is known as Plagioclase Feldspar. More specifically Albite and has the chemical formula NaAlSi3O8.

Sodium aluminum silicate is part of a group of minerals known as plagioclase feldspars. Specifically albite and has the chemical formula NaAlSi3O8.
