Composition of the crust The most abundant minerals in the crust. More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars (plagioclase (39%) and alkali feldspar (12%)). Other common silicate minerals are quartz (12%) pyroxenes (11%), amphiboles (5%), micas (5%), and clay minerals (5%).he most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1).

What is the most abundant mineral group in earth's crust? As others have stated, the silicate mineral group. Of the silicates, the most abundant are the tectosilicates (3-D framework of SiO4 tetrahedra where all the oxygen are bonded … to adjacent tetrahedra). This group includes minerals like quartz, plagioclase, and potassium feldspar.

Minerals This list of minerals and specific articles about each mineral species are all focused on minerals as they naturally occur within rocks and sediments. More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars (plagioclase (39%) and alkali feldspar (12%)). Other common silicate minerals are quartz (12%) pyroxenes (11%), amphiboles (5%), micas (5%), and clay minerals (5%). The rest of the silicate family comprises 3% of the crust. Only 8% of the crust is composed of non-silicates — carbonates, oxides, sulfides, etc 1.

Geology: What are the most abundant minerals on Earth's crust? Now, here, we need to specify if we need to see the minerals ON the Earth's surface or IN the Earth's crust. ON the Earth's surface, the most abundant minerals would be Quartz, Feldspars, Clay minerals, Ice, Chlorite, etc. IN the Earth's crust, the most abundant minerals are Feldspars (about 40-60%) and Quartz (about 30-50%).

- Rock crystal quartz, the most common gem variety of quartz crystal, is, like all quartz, formed from the two most abundant elements in the earth's crust: silicon and oxygen. For centuries early civilizations believed that these pinhead size to nearly a meter in diameter rock crystals were permanently frozen ice.

Rock (geology) The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock.
