Here are a few common rock specimens and which of the two minerals they contain: Diorite – both feldspar and quartz; Gabbro – feldspar; Granite – both feldspar and quartz; Peridotite – both feldspar and quartz; Rhyolite ... WebQuartz occurs as an important constituent of those igneous rocks which have an excess of silica, such as granite, rhyolite, pegmatite. It is extremely resistant to both mechanical and chemical attack, and thus the breakdown of igneous rocks containing it yields quartz grains which may accumulate and form the sedimentary rock sandstone.
