| Based on the NingNa county of sichuan s Yin Changgou-Qi Luogou as the research object, by regional metallogenic geological background of ore-controlling structure, and lithological association ore-controlling cretaceous. the ore, stable isotopes and trace elements and rare earth elements, etc, they studied the coupling relationship between the silver, and summarizes the lead-zinc deposit metallogenic regularities, establishing ore-prospecting criteria and prospecting model. Then, with the silver of metallogenic regularities of ore prospecting model, and the comprehensive other land, and remote data with Yin Changgou-Qi Luogou, the section of metallogenic regularities of similar area (target). Finally, estimate the rest of ore resource delineating the vision.Building in southern Yangtze plate passive continental margin on the early Paleozoic to kunming - nearly SN ZhaoJiao oil-bearing rifting, listens to the north - with depression and the slot dongchuan the days near baoshan - qiaojia fault. The Yin Changgou-Qi Luogou area located on the Qi Luogou ditch west wing, double anticline axis and abuts anticline. As a regional anticline anticline in the near east, west, north and south, to tilt toward the south, the axis of the 0.932 for general Ann formation, two-wing by sinian, Cambrian, yingshan formation, etc. The formation of mainly for sinian and Cambrian, times before the formation and 4 sinian system for.The area - the ore-bearing layer is lighted on the sinian section (ec) group, in Zbd3 215°~ 245°∠23°~38°, lithology, clastic dolostone is by hydrothermal dolomitization, dense the ribbon like jasper paleokarstification dolostone, etc. Zone, not seen.There ore mineral sphalerite and galena, tetrahedrite, pyrite, white lead, zinc mine, wheel miner's. Wall-rock alteration are mainly dolomitization, etc. The Yin Changgou-Qi Luogou area, the main ore-control factors: (1) the lithological ore-controlling, from the Cambrian next series field (?1q )group (ec), the sinian 1q (zbd) and light group avalokitesvara (zbg) constitutes the geochemical gradient belts, forming good store ore systerms. (2) structure and structural combination, ore-controlling structures, strong shear fault, "into" type structure, fracture and horizontal, vertical, or small buckling of small anticline, as the main part of the ore. (3) metallogenic tectonic evolution and controlling process with many characters.Through the stable isotopes and trace elements and rare earth elements, study area of ore-forming materials and ore-forming fluid has shell - mixed characteristics. 122°~ 236°uniform temperature, temperature - c. The copper deposit types for shell - mixed with the characteristics of low - the hypabyssal hydrothermal pb-zn deposit.Research areas delineated total 18 lateral fold, and 1 by 18 sections of the longitudinal fold. By transverse and longitudinal fold drape of A vision for the region, by lateral fold or longitudinal fold constitute the area for class B vision zone. Then, the volume of metallogenic coefficient method, A kind of vision estimates and class B vision result, the vision of resource estimates 1.3 million ton, 9.4 million ton, respectively.
