Give four types of nonsilicate minerals.

Answer 1

1. Carbonates: Nonsilicate minerals like calcite (CaCO3) and dolomite (CaMg(CO3)2) fall under the carbonate group. These minerals are composed of carbonate ions bonded with metal ions.

2. Sulfates: Nonsilicate minerals such as gypsum (CaSO4·2H2O) and anhydrite (CaSO4) are classified as sulfates. They contain sulfate ions bonded with metal ions.

3. Halides: Nonsilicate minerals like halite (NaCl) and fluorite (CaF2) belong to the halide group. These minerals are formed by the bonding of halogen elements, such as chlorine or fluorine, with metal ions.

4. Oxides: Nonsilicate minerals like hematite (Fe2O3) and magnetite (Fe3O4) are categorized as oxides. They consist of metal ions bonded with oxygen ions.
