Identifying Granitoids and Other Granite Rocks
That's because feldspar always forms before quartz. Feldspar is mainly silica (silicon oxide), but it also includes aluminum, calcium, sodium and potassium. Quartz—pure silica—won't start forming until one of those feldspar ingredients runs out. There are two types of feldspar: alkali feldspar and plagioclase.

Orthoclase Mineral Information photos and Facts, gems
The most noticeable difference between orthoclase and microcline is that the latter shows clearly its triclinic symmetry by its twinning, and its optical properties, while in orthoclase the twinning is so minute as to be unobservable and the optical properties are similar to those of monoclinic crystals.

Feldspar
Feldspar is ultimately an industrial mineral and we have to accept that its quality is controlled by what's good enough for industry. * (Note the difference in the ratio of silica and alumina between feldpars, spodumene, and nepheline syenite. There is less silica in the latter two. The crystal structure explains this.

Mafic Vs. Felsic Rocks: Know the Difference
Mafic rocks are dark in color. Common mafic rocks include basalt, dolerite, and gabbro. It is of, relating to, or denoting a group of lightcolored minerals, including feldspar, feldspathoids, quartz, and muscovite. It is also known to be a mnemonic, combining (fe) for feldspar, (l) for lenad or feldspathoid, and (s) for silica.
