Quartz vs Quartzite vs Granite Kitchen Countertops ...

Because this igneous rock is an amalgam of quartz, feldspar, amphiboles, micas and assorted trace minerals, the sheer variety of plutonic rock available for quarrying is breathtaking. If granite is composed of lots of quartz, it tends to be transparent, while a predominance of feldspar tints the rock pink or white.

Granite

In the vast majority of cases it contains more feldspar than quartz. Trondhjemite is a leucocratic variety of tonalite. It is a granitic rock, but not true granite because the feldspar it contains is sodic plagioclase, not alkali feldspar. Width of sample from Norway is 10 cm. Syenite may be similar to granite, but it does not contain enough quartz.
