摘要	The Dajing Cu-polymetallic ore deposit in Linxi county, Inner Mongolia Autonomous Region, China, is a large-scale Cu-Sn-Ag-Zn-Pb deposit in the southern section of the Da Hinggan area. The delta(34)S values of chalcopyrite, pyrite, sphalerite, and galena sulfides collected from the Dajing ore deposit range from -1.8parts per thousand to +3.8parts per thousand with an average of +0.65parts per thousand. The narrow distributions of the delta(13)C values round -5parts per thousand and the delta(34)S values with similar to+1parts per thousand peak value indicate that the sulfur and carbon of the ore-forming fluid are derived from a hypomagma and exclude the possibility that the,hosted Upper Permian Linxi Formation strata provide a certain amount of sulfur and carbon. The Pb-206/Pb-204, Pb-207/Pb-204 and Pb-208/Pb-204 ratios of sulfide ores range respectively within 18.257similar to18.368, 15.476similar to15.609, and 37.916similar to38.355 with the model ages of 122similar to209 Ma. But, the black shale contains higher radiogenic lead with the Pb-208/Pb-204 ratios of 18.473similar to20.156, differing from the ores. However, the Pb-206/Pb-204, Pb-207/(204)Pn and Pb-208/Pb-204 ratios of the ore, basic-ultrabasic dike and feldspar leads are similar and lie on the same lines in the diagrams of Pb-208/Pb-204 vs. Pb-206/Pb-204 and Pb-207/Pb-204 vs. Pb-206/Pb-204. The analysed feldspars were separated from granite in the neighborhood of the Dajing ore deposit. For the mixing lines, the two end members are respectively upper mantle and orogenic belt that means mixing the matters of the upper mantle and of orogenic belt prior to the Mesozoic. All the evidences strongly support that the metallogenic elements were carried by the hypomagma. Therefore, the Dajing ore deposit is a typical magmatic-hydrothermal vein type of ore deposit associated with subvolcanic rocks.
