The formation and evolution of magma have experienced three stages:① thermal fluid led to higher partial melting of lithosphere mantle and then formed hypoalkaline basalt with saturated initial sulfur when ascending asthenosphere contacted with the lithosphere mantle;② the initial magma intruded into the lower crust to form magma chamber, the crystallization of magma produced stratiform-like cumulate, including olivine, hypersthene, augite, magnetite, and then formed residual gabbroic magma with the participance of crustal material;③ the residual magma and ore-bearing cumulate intruded upward successively to shape original mafic complex rocks in Wuxing when the magma chamber cracked.
