Sandstone is a type of clastic sedimentary rock with sand-sized minerals or sand grains. Its two chief minerals are quartz and feldspar.
Quartz and feldspars are the most common minerals found in continental crustal rocks.
Quartz itself is the mineral. Its formula is SiO2. Rocks are aggregates of minerals, so an example of a rock that contains a lot of quartz is granite.
Granite is a rock made of several minerals; Quartz, Feldspar, Hornblende, Mica brown.
Mafic, igneous rocks
Gneiss contains the minerals mica, quartz, feldspar, amphibole, garnet, and pyroxene.

Syenite is not granitic. Quartz is one of the main minerals found in granitic rock. Syenite contains little or no quartz, but otherwise has the same general composition as granite.

The most abundant rock forming minerals are the silicates, like feldspars, micas, and quartz.
Less than. The moon rock density is greater in ferromagnesion and nickel content, with greater density, whereas silicate rocks contain largely quartz and feldspar minerals.
