Feldspar and quartz are examples of what minerals?
The group of minerals in Feldspar contain framework tectosilicates. The compositions of the major elements in the usual feldspars can be identified by three endmembers: Potassium-Feldspar, Albite, and Anorthite.
What rock contains both amphibole and potassium feldspar?
Granite is a rock containing both amphibole and potassium feldspar.
Is feldspar granitic?
Yes, Granite is composed mainly of quartz and potassium feldspar
The dating method that can be used in some cases on rocks as young as 50000 years old that contain feldspar mica or amphobole is?
potassium-argon
What type of cleavage does feldspar have?
Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
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.
Potassium rich feldspar rocks?
barium
What is the scientific name for feldspar?
Feldspar is not a specific substance, but a class of aluminosilicates of potassium, sodium and calcium.
What element makes up feldspar?
It depends on the type of feldspar. Potassium Feldspar (also called K-Spar), contains potassium, aluminum, silicate: KAlSi3O8. Plagioclase Feldspar, on the other hand, contains calcium or sodium, aluminum, and silicate: NaAlSi3O8 or CaAl2Si2O8.
Is orthoclase calcite?
No. Orthoclase is a variety of potassium feldspar.
What happens to potassium feldspar during hydrolysis?
Swag
