Quartz Common Minerals
In igneous rocks and pegmatites, quartz usually occurs with potassium feldspars, muscovite, biotite and amphiboles. In sedimentary rocks or metamorphosed sedimentary rocks, quartz may be associated with potassium feldspar, calcite, dolomite or a variety of clay minerals.

Experimental Study of Mineralogy, Petrophysical, and Thermal
Feldspars have a somewhat negative correlation with thermal properties and show no correlation with petrophysical properties. These findings are essential in predicting the behavior of sedimentary rocks in various applications, including geothermal energy systems, oil and gas reservoirs, and underground thermal storage systems.

Feldspars occur in most igneous and metamorphic rocks. They are less common in sedimentary rocks as they tend to break down to clay minerals in the weathering environment.

Sedimentary Rock Identification – Physical Geology
When you split a rock into very small pieces, the pieces are different from each other. For example, when you break granite apart, you get small pieces of quartz (clear), feldspar (pink or white), and mica (black). When you split a mineral into pieces, you still have pieces of the same mineral.

Description of Minerals and Rocks - University of Illinois Urbana
Felsic igneous rocks are made up primarily of feldspar and quartz (silica). Mafic igneous rocks are made up primarily of minerals rich in iron and magnesium. Felsic rocks are usually light to intermediate in color, and mafic igneous rocks are usually dark. Sedimentary Rocks Most of the rocks native to Illinois are sedimentary rocks.
