Ore formation by magmatic concentration occurs when economically valuable minerals crystallize directly from a cooling magma or become concentrated due to physical and chemical processes within the magma itself. Magmatic differentiation plays a central role, as it leads to the separation of minerals based on differences in density, melting points, and chemical composition. As magma cools, early-forming minerals like olivine, pyroxene, and magnetite may settle due to gravity, forming cumulate layers
