Both minerals have a vitreous luster, a white streak, and contain oxygen.
All four minerals—quartz, pyroxene, olivine, and calcite—contain silicon as a common element. Quartz and olivine are silicate minerals, meaning they are composed primarily of silicon and oxygen, while pyroxene is also a silicate that includes other metal elements. Calcite, although a carbonate mineral, contains carbon and oxygen in addition to calcium but does not contain silicon. Thus, silicon is specifically common to the silicate minerals among them.

The six most common minerals in the Earth's crust are feldspar, quartz, mica, amphibole, pyroxene, and olivine. Feldspar is the most abundant, making up about 60% of the crust, while quartz is the second most prevalent mineral. Mica, amphibole, and pyroxene are common in igneous and metamorphic rocks, and olivine is primarily found in ultramafic rocks. Together, these minerals contribute significantly to the composition of various rock types.
The mineral assemblage of Rhyolite is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2) and biotiteand hornblende are common accessory minerals. More importantly quartz has got to comprise more than 69% of the rock.

Minerals are solid inorganic substances that occurs naturally. Eight of the most common rock forming minerals are quartz, feldspar, mica, amphibole, pyroxene, olivine, kaolinite and muscovite.

Quartz scratches dolomite, while olivine scratches pyroxene.
The seven most common minerals found in the Earth's crust are quartz, feldspar, biotite, amphibole, pyroxene, olivine, and calcite. These minerals are abundant and widely distributed across various geological environments.
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.

Rocks are made of minerals. Only a few minerals are rock forming and most rock is made from a combination of the commonest of these such as feldspars, quartz, mica, olivine, calcite, pyroxene and amphiboles.
The 20 minerals that make up most of the rocks of Earth's crust are known as rock-forming minerals. These minerals include quartz, feldspar, mica, and amphibole, among others, and play a crucial role in shaping the composition and characteristics of the Earth's crust.
