* Silicates: These minerals contain silicon and oxygen, which combine to form the basic building block of silicate minerals: the silica tetrahedron (SiO4). Silicates are the most abundant group of minerals in the Earth's crust, making up about 92% of its volume. Examples include quartz, feldspar, mica, and olivine.

* Non-silicates: This group encompasses all minerals that do not contain the silicate tetrahedron. They are less abundant than silicates but still play important roles in the Earth's composition and various industries. Examples include carbonates (like calcite and dolomite), oxides (like hematite and magnetite), sulfides (like pyrite and galena), halides (like halite and fluorite), sulfates (like gypsum), and native elements (like gold, silver, and copper).

It's important to note that this is a broad classification and there are many sub-groups within each category.
