Sulfur minerals are naturally occurring compounds that contain the element sulfur. They are often found in volcanic regions and sedimentary deposits. Common examples include gypsum, barite, and pyrite. These minerals play a crucial role in various geological processes and can be important sources of sulfur for industrial applications. In addition to their industrial uses, sulfur minerals are significant in agriculture, as they contribute to soil fertility. They can also be indicators of certain environmental conditions. Understanding these minerals helps geologists and environmental scientists assess natural resources and ecological health.
