Detailed explanation-1: -Precipitation is the reverse process, in which ions in solution come together to form solid minerals. Precipitation is dependent on the concentration of ions in solution and other factors such as temperature and pressure. The point at which a solvent cannot hold any more solute is called saturation.
Detailed explanation-2: -Minerals can form from volcanic gases, sediment formation, oxidation, crystallization from magma, or deposition from a saline fluid, to list a few.
Detailed explanation-3: -Solid-state diffusion: (pressure-cooking) can cause ions to reorganize themselves into new minerals without melting having occurred when a solid is heated or compressed.
Detailed explanation-4: -Hydrothermal Environments. Even in the driest places on Earth, water is involved in forming minerals. Metamorphic Environments. Metamorphic rocks all had previous “lives.” Igneous Environments. Pegmatitic Environments. Weathering Environments.
