Which ferromagnesian minerals and which of the feldspar's would be the first minerals to crystallize?
olivine and anorthite
What is feldspar sand?
It is sand composed primarily of weathered particles of feldspar, as opposed to sand composed of quartz or gypsum.
What minerals does the rock granite always contain?
granite has its composition _ quartz+alkali feldspar
What is the difference between red granite and granite?
The composition changes the appearance and colour of the granite. A granite that appears more red in colour will have more of the mineral orthoclase feldspar, whereas the lighter and more white in appearance will have less orthoclase and maybe more plagioclase feldspar and quartz in the composition.
Does sandstone have feldspar in it?
Sandstone will often contain feldspar, but some sandstones are composed entirely of quartz.

Granite is what type of mixture?
Granite is composed of quartz. feldspar, mica and amphibole minerals. There are often other materials in the composition, but these are the main parts of granite.

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.
