What rock contains aluminum silicates and other minerals?
Bauxite is the main source of aluminum. Albite is a feldspar mineral and is a sodium aluminum silicate All rocks contain other minerals.
What are the types of feldspar?
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
How does metamorphism affect baslt?
Basalt when metamorphosed turns to the following rocks: (LEAST PRESSURE AND TEMPERATURE TO THE MOST) + mineralogy -Greenschist-albite, epidote, chlorite -Amphibolite-amphioble, plagioclase feldspar -Granulite-calcium-rich pyroxene and plagioclase feldspar -Eclogite-sodium-rich pyroxene and garnet
Is the change from feldspar to clay minerals an example of chemical weathering?
It depends on the type of feldspar you're wondering about. I'm only 100% sure on one K-spar (Orthoclase) and one end-member of Plagioclase. Orthoclase (and probably the other K-feldspars as well - Microcline and Sanidine) weather to Illite, the most stable of the clay minerals: Orthoclase + CO2 + H2O ---> Illite + [K+ + HCO3- + SiO2]aq Albite (the Na-end-member of the plagioclase solid solution (Anorthite is the Ca-end-member, which may well weather in the same manner) weathers to Kaolinite: Albite + CO2 + H2O ---> Kaolinite + [Na+ + HCO3- + SiO2]aq
What is microline feldspar?
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.
Can you find albite in the US?
Yes, albite is a common mineral found in many states from California to Maine.
Is albite a salt?
Albite is a salt: a sodium-aluminium silicate, NaAlSi3O8.
Is albite also known as lime feldspar?
Lime feldspar is a synonym for anorthite (CaAl2Si2O8) not for albite (NaAlSi3O8).
What is albitization?
Albitization is the conversion of a mineral into albite, a form of feldspar.
What is albite used for?
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.

What is twinning?
Twinning is formation of twin crystals like Siamese twins during crystallization which follow defined twin laws e.g. Spinel and Albite.
What is Sodium aluminum silicate?
Sodium aluminum silicate is part of a group of minerals known as plagioclase feldspars. Specifically albite and has the chemical formula NaAlSi3O8.
