What kind of rock is Amazonite?
No, it is not a rock, it is a mineral/crystal.Amazonite is a green variety of microcline feldspar, which does occur in some intrusive, granitic Igneous rocks.
What is the name of the Mineral used in glass and ceramics a feldspar?
microcline is the answer
What do all these minerals quartz plagioclase feldspar microcline feldspar hornblende and biotite have in common?
They are all found in Granite
Which large blocky feldspar is found most often in association with large muscovite crystals?
It is usually potassium feldspar, either microcline or orthoclase.
What is amazonite?
An amazonite is a gem variety of microcline feldspar, varying from bright verdigris to bluish-green.
What are the three uses of microcline?
1.The green variety of microcline amazonite is used as an ornamental lapidary material.2.Microcline is used mainly in the manufacture of porcelain. It is ground very fine and mixed with kaolin and quartz. Upon heating, the feldspar fuses and acts as a cement binding the materials together. Fused feldspar also is the main constituent in the glaze on porcelain.3.Sometimes microcline is also used to supply alumina in the manufacture of glass.by Maham kainat :P

What is an amazonstone?
An amazonstone is a blue-green variety of microcline feldspar used as a gemstone, found at Crystal Peak and Pike's Peak in Colorado.
Which mineral is commonly found in the three matamorphic rocks slate schist and gneiss?
granite
What is an example of a mineral in the triclinic crystal system?
plagioclase, microcline, rhodonite, turquoise, wollastonite, amblygonite, and many more.
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.
What are two feldspars found in granite?
Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.
