摘要：

The isotopic composition of lead from a total of 53 samples of galena from 18 VHMS deposits shows a range between 17.437 and 18.111 for Pb-206/Pb-204; 15.484 and 15.630 for Pb-207/Pb-204 and 37.201 - 38.027 for Pb-208/204. The results show a systematic trend with the leads of the Sibay, Barsuchiy Log and Djusa deposits being most radiogenic by comparison with those of Bakr-Tau and Oktiabrskoe which are the least radiogenic deposits. The Bakr-Tau and Oktiabrskoe deposits occur within most primitive fore-arc rocks at the lower part of the Baymak-Buribay formation, which contain lavas of boninitic affinity. The Sibay, Barsuchiy Log and Djusa deposits are found in intra- and back-arc setting and are hosted by a sequence of bimodal tholeiites. The deposits in "arc" settings such as the Balta-Tau, Gai and Alexandrinka deposits occupy an intermediate position. This trend is explained in term of mixing between mantle wedge and continental blocks.
