the earth's crust
The most important class of rock-forming minerals on Earth is silicate minerals. These minerals make up the majority of the Earth's crust and are characterized by their silica tetrahedron structure. Examples of silicate minerals include quartz, feldspar, and olivine.

Quartz is one of the eight basic rock-forming minerals, also known as the "Rock-Forming Minerals of the Earth's Crust." It is abundant in igneous, sedimentary, and metamorphic rocks, contributing to the structure and composition of many rock types. Along with quartz, other common rock-forming minerals include feldspar, mica, amphibole, pyroxene, olivine, calcite, and garnet.
Silicate minerals are the most important class of rock-forming minerals on Earth. They make up over 90% of the Earth's crust and are essential components of many common rock types, including granite, basalt, and quartz. Silicate minerals are defined by their silicon-oxygen tetrahedral structure.
95%. All others are referred to as rare minerals.

An Introduction to the Rock-Forming Minerals was created in 1966.
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.
No. Silicates are the largest group of rock forming minerals.

Yes, the most common rock-forming minerals in Earth's crust are primarily silicate minerals. Silicates, which contain silicon and oxygen, make up about 90% of the Earth's crust and include important minerals like feldspar, quartz, and mica. Non-silicate minerals, while present, are much less abundant in comparison.
