英文摘要	The yangshan gold deposit, wenxian county, gansu province, containing 308 t an with average grade of 4. 74g/t, is now ranked as the china' s largest gold deposit. locating in western qinling orogen, central china, it is a syn-collisionally formed carlin-like gold deposit. its orebodies are controlled by an east-trending shear-zone and hosted in the devonian carbonaceous carbonatephyllite-slate sequence or the granite-porphyry dikes intruding into the devonian strata. the delta(13) c-co2(pdb) and delta(13) c-ch4(pdb) ratios of fluid inclusions within quartz separates range - 2. 5 parts per thousand similar to - 5. 6 parts per thousand and - 23.1 parts per thousand similar to - 32. 6 parts per thousand, respectively, suggesting that the ore-fluids have been mainly sourced, through metamorphism and/or reworking, from the devonian strata or/and similar lithologies which comprise carbonaceous phyllite, slate, chert and carbonate. this conclusion is strongly supported by the delta o-18 values of the early- and main-stage ore fluids, which range from 9. 5 parts per thousand to 15.3 parts per thousand, with corresponding delta d values between - 86 parts per thousand similar to - 73 parts per thousand. two delta o-18 values of late ore-forming stage ore-fluids are 2. 7 parts per thousand and 6.8 parts per thousand, implying a significant input of meteoric water. in general, the ore-forming fluid-system varies from early, deep, metamorphic fluid to late, shallow, meteoric water. it is worthy of stating that the above results and understandings are consistent with conclusions drawn from our studies of fluid inclusions and ore geology.
