WebApr 15, 2024 · Minerals in cogenetic ore-bearing intrusions are sensitive to various factors of the magma processes, such as ƒO 2, temperature and melt composition. As a result, they serve as a valuable tool for estimating the crystallization conditions and compositions of their equilibrium melt phase, e.g., [ 14, 15, 16, 17, 18, 19, 20, 21, 22 ]. WebCrystallization and Magmatic Differentiation Liquid magma is less dense than the surrounding solid rock, so it rises through the mantle and crust. As magma begins to cool and crystallize, a process known as magmatic differentiation changes the chemistry of the resultant rock towards a more felsic composition.
