The prospecting for porphyry copper deposits in Beishan area has been paid much attention by geologists in China.

Gongpoquan, an important porphyry copper deposit, was discovered in Beishan area, and many geological prospecting companies have

recently made remarkable breakthrough in the ore-prospecting work in periphery and deep-seated areas, and hence the reserves of

Gongpoquan are being gradually increased. Using the regional geochemical data obtained in the ore field, the authors studied the

regional metallogenic geological and geochemical setting and the distribution regularity of the ore-forming element association

(Cu, Ag, Au), the indicator element associations (Cu-Pb-Zn-Ag-C and W-Mo-Sn-Bi), and the metallogenic environmental element

associations (U-P-F；Fe-V-Ni-Cr). On such a basis, this paper puts forward a regional geological-geochemical structural model for

the Gongpoquan porphyry copper deposit, which is of some significance in enriching and improving the related theoretical models.
