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.

According to the heterogeneous migmatite and granite of South and North Dabie Blocks, and the formula △h=h which was inferred in this paper, the melting of metamorphio rock might make NB uplift about 4. 4km, but SB only about 1. 9km. Therefore, the difference of melting degree of metamorphic rocks of NB and SB led to the volume different, and this could be one of the reasons of different uplift of NB and SB.

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.
