The Huangtupo middle copper-zinc deposit is located at the central part of Kalatage copper polymetallic belt in eastern Tianshan. This deposit belongs to volcanic hosted massive sulfide deposit（VHMS）or volcanogenic massive sulfide deposit（VMS），which is hosted in the Early Silurian marine volcaniclastic-sedimentary sequence. The ore bodies are hosted in intermediate volcanic breccias and felsic tuff assemblages with massive orebody at the upper and vein orebody at the lower part. The structures of ores are massive， disseminated， banded and veinlet. This paper reports He and Ar isotopic data of fluid inclusions trapped by pyrites.3 He/ 4He ratios range from 0.11 to 0.94 Ra with He derived from mantle varying from 1.71% to 10.97%. 40Ar/ 36Ar ratios range from 301.40 to 425.98 with 40Ar* content from 1.96% to 30.63% . Combining inclusions assemblages， hydrogen， oxygen and sulfur isotopic characteristics of the Huangtupo copper-zinc deposit， it can be concluded that the mantle-derived fluids and seawater containing crustal 4He and atmospheric Ar were involved in the mineralization， and the seawater is dominated.
