摘要
Shimensi tungsten polymetallic deposit is located in Mesozoic Cu-Mo-Au-Ag-Pb-Zn ore belt, Jiangnan block, Lower Yangtze metallogenic province. Based on the regional geological setting and metal- logenic geological feature of the deposit this paper analyses the ore-control factors in detail, such as coun- try rock, host rock and fractures in the working area. The country rock is biotite granodiorite of Late Jin- ning period which is recognized the S-type granite in syn-collision volcanic arc developed on basis of imma- ture continental crust during Neo-proterozoic era; the host rock, Yanshanian porphyritic biotite granite, fine-grained biotite granite, granoporphry which are Si, A1 saturated rock of Ca-alkali series, the S-type granite derived from melting and cognate evolution of Jiuling batholith under intra-continental collisional compression; Shimensi fracture and Xianguoshan-Dhutang-Shiweidong basemental fractures, the ore-con- trol fracture whose intersection controls emplacement of the ore-bearing granite and distribution of W- polymetallic deposits.
