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.

Combined with related rare earth element and trace element geochemistry of Huangshaping granites and ore-bearing skarn, it is concluded in this paper that the age of 154 Ma should represent the metallogenic epoch of the deposit, and that there existed a close relationship between the ore-forming process of the deposit and the granite porphyry, which were both formed during the peak stage of Early Yanshanian large-scale rock-forming and ore-forming activities in South China.

The analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefieldsthat the anomalies of cover structure confine most Cu-Au deposits and Fe-Cu deposits within their scopethat the geochemical anomalies and lithofacies-paleogeographical anomalies are major geological factors leading to trataboundness of some Cu-Au depositsthat the anomalies of rock operties provide the favorable chemical and physical conditions for the ore-forming process, including the seepage, circulation,convergence and deposit of ore-bearing hydrothermal solutionthat the anomalous ctive stage of Mesozoic magmatite is almost consistent with the major mineralization epoch of the Fe,Cu deposits, and the structure of multi-levels,and the zoning in magmatic system determine the spatial distribution of the mineralization system.
