| Lead and Sulfur Isotope Geochemistry of the Huangshaping Lead-Zinc Deposit, Hunan Province |
| The Huangshaping lead-zinc deposit is one of the typical deposits in Xiangnan (southern Hunan Province). This deposit occurs mainly in granite-porphyry and quartz porphyry. The ores are mainly composed of Pb, Zn sulfides in SN-trending Baoling reversed anticline and Guanyindazuo reversed anticline. Sulfur isotope analyses show that δ34S values of pyrites vary in the range of -2.2‰~17.2‰. Pb isotope analyses reveal that 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios of the ore lead are 17.893~18.772, 15.580~16.045 and 38.490~41.560 respectively. The research results suggest that sulfur might have been derived from the mixing effect of magma and seawater(strata). The research also shows that anomalous lead has derived from magma |
