undefined The main characteristics of the major mineral groups are as follows:

1. Silicates: Silicates are the most abundant mineral group and are characterized by their silicon-oxygen tetrahedral structure. They often form the framework of many minerals and have a wide range of chemical compositions and physical properties.

2. Carbonates: Carbonates are minerals composed of carbonate ions (CO3^2-) combined with metal ions, such as calcium (Ca) or magnesium (Mg). They commonly form sedimentary rocks like limestone and are prone to dissolution in acidic environments.

3. Oxides: Oxides consist of metal cations bonded to oxygen ions. They include minerals like hematite (Fe2O3) and magnetite (Fe3O4), which are important sources of iron.

4. Sulfides: Sulfides are minerals composed of metal cations bonded to sulfur ions. They often form in hydrothermal environments and include minerals like pyrite (FeS2) and galena (PbS).

5. Sulfates: Sulfates are minerals composed of sulfate ions (SO4^2-) combined with metal cations. They commonly form in evaporite deposits and include minerals like gypsum (CaSO4·2H2O) and barite (BaSO4).

6. Halides: Halides are minerals composed of halogen ions (e.g., chloride, fluoride) combined with metal cations. They often form in evaporite deposits and include minerals like halite (NaCl) and fluorite (CaF2).

7. Native elements: Native elements are minerals composed of a single element. Examples include gold (Au), silver (Ag), and diamond (C).

Each mineral group exhibits distinct chemical compositions, structures, and properties, which influence their formation, occurrence, and uses in various geological processes and industries.
