Feldspar Distinctions, Characteristics & …

Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. They usually have a glassy luster. Feldspar is called a rock-forming mineral, very common, and usually makes up a large part of the rock. In sum, any glassy mineral thats slightly softer than quartz is very likely considered a feldspar.

Quartz and feldspar

The bad news is that sometimes the curved conchoidal surfaces can flash as well, but this usually happens with the clear varieties of quartz (which you already know isnt feldspar anyway). So, if the mineral has cleavage and sparkles, it may be feldspar. If no sparkles, no matter how you rotate it in the light, it may be quartz.

Quartz-porphyry - Wikipedia

In addition to quartz there are usually phenocrysts of feldspar, mostly orthoclase, though a varying amount of plagioclase is often present. The feldspars are usually full and cloudy from the formation of secondary kaolin and muscovite throughout their substance. Their crystals are larger than those of quartz and sometimes attain a length of two inches. Not uncommonly scales of biotite are visible in the specimens, being hexagonal plates, which may be weathered into a mixture of chlorite and epidote.

Micrographic texture - Wikipedia

In petrology, micrographic texture is a fine-grained intergrowth of quartz and alkali feldspar, interpreted as the last product of crystallization in some igneous rocks which contain high or moderately high percentages of silica. Micropegmatite is an outmoded terminology for micrographic texture. This fine-grained texture is similar to the coarser intergrowths in certain pegmatites and coarse granitic veins; the quartz forms angular patches scattered through a matrix of feldspar. In polarized lightthe sep…
