These minerals are usually dark in color, Ferromagnesian Minerals minerals are also denser than other rock-forming minerals.

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.
The major family of rock-forming minerals is the silicate minerals. These minerals are made up of silicon and oxygen atoms, often combined with other elements like aluminum, iron, and magnesium. Some examples of silicate minerals include quartz, feldspar, and mica.
A mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted is known as ore, while the ordinary rock does not has any economical value.
Most rock-forming minerals are silicates because silicon and oxygen are two of the most abundant elements in the Earth's crust. Silicates are composed of silicon and oxygen atoms bonded together, along with other elements such as aluminum, iron, and magnesium. These minerals form through processes like crystallization from magma or chemical weathering of other rocks.
Rock-forming minerals 1. Silicates - are minerals which consist of silicon and oxygen with some metals or nonmetals. Some rocks which have these minerals are granite, sandstone, basalt, gneiss and quartzite. 2. Carbonates - are minerals which consist of carbon, oxygen and some other elements. Rocks in which these minerals are found include marble, limestone and dolomite. 3. Oxides - are minerals which consist of oxygen and some other elements. They are found in rocks such as sandstone and shale. Although there are about 3000 different minerals found on Earth, there are only very few of them which form rocks.
minerals differ in appearance and texture
Minerals (other than elemental minerals) are combinations of elements.

Minerals may get changed to other minerals forming a new rock. Mineral grains also become aligned in response to the increased pressure.

Mafic rocks have higher concentrations of dense minerals like iron and magnesium compared to felsic rocks, which are rich in lighter minerals like quartz and feldspar. This difference in mineral composition contributes to the higher density of mafic rocks.
Silicate minerals are the most important class of rock-forming minerals on Earth. They are the building blocks of most rocks found on the planet and are composed of silicon and oxygen atoms, in combination with other elements such as aluminum, iron, magnesium, and potassium. Examples include quartz, feldspar, and mica.
