Mineral deposits are natural accumulations of minerals found in the Earth's crust. These deposits can form through various geological processes, such as volcanic activity, sedimentation, or hydrothermal solutions. They are often mined for valuable resources like gold, copper, and iron ore, which are essential for various industries. The location and concentration of mineral deposits can vary widely, influenced by factors like plate tectonics and erosion. Geologists study these deposits to understand their formation and to locate new sources of minerals. Sustainable mining practices are important to minimize environmental impact while extracting these resources.
