The material you're describing sounds like granite, which is primarily composed of three minerals: feldspar, mica, and quartz. These minerals give granite its characteristic speckled appearance and durability. Feldspar is the most abundant mineral, while quartz adds hardness, and mica contributes to the shiny appearance of the rock. Together, they create a strong and aesthetically pleasing natural stone commonly used in construction and countertops.
Oxygen and Silicon
Granite
Granite is a material that is mostly made of the mineral quartz. It is a common type of igneous rock that contains high amounts of quartz along with other minerals such as feldspar and mica.
Most sand is made up mostly of pulverized quartz. Quartz is one of the most abundant minerals on Earth and is composed of silicon dioxide (SiO2). When rocks containing quartz break down due to weathering and erosion, they form sand, which is primarily made up of small particles of pulverized quartz.
Gneiss is predominantly made up of minerals such as quartz, feldspar, and mica. It typically consists of alternating layers of light and dark minerals that have undergone intense heat and pressure, resulting in a banded appearance.
The bulb is usually made of: Soft glass made from silica, trona (soda ash), lime, coal, and salt.
Granite is a rock made of several minerals; Quartz, Feldspar, Hornblende, Mica brown.
Quartz will probably be found in most igneous and metamorphic rocks. Granite is a classic example of a rock with quartz in it. Search for images of "granite." Quartz sandstone is another rock practically made entirely up of quartz.
Oxygen and Silicon
Quartz and coal are both naturally occurring substances and minerals. Quartz is a mineral composed of silicon and oxygen atoms, while coal is a sedimentary rock made up of organic matter primarily from plant material.
Granite
Quartz is made up of silicon and oxygen (SiO2) and has a distinct crystal structure. It is one of the most common minerals on Earth and has a wide range of colors and varieties. Unlike other silicate minerals, quartz is highly resistant to weathering and is very hard (7 on the Mohs scale).
