chemical sediment

Chemical sedimentation is the process where solid material settles out of a fluid, like water or air, due to chemical principles. This differs from physical sedimentation, which involves particles settling based on factors like density and fluid viscosity. Chemical sediments form through precipitation from solutions, influenced by conditions such as pH and redox potential. Examples include rocks like rock salt and gypsum, which form when dissolved minerals precipitate out of water. This process is crucial in geochemistry, acting like a large-scale chemical analysis that separates Earth's elements into distinct deposits.12
