中文摘要：

黄家湾矿是贵州遵义地区寒武系底部新发现的黑色页岩镍钼多金属元素矿床。根据形态硫测试结果，文章分析了黄家湾下寒武统牛蹄塘组黑色页岩剖面和矿石中不同形态硫（硫酸盐硫、黄铁矿硫、有机硫）的特征，推测镍、钼金属富集层处还原性硫的来源。

英文摘要：

Huangjiawan Ni-Mo polymetallic deposit in the bottom of the lower Cambrian black shale in Zunyi, Guizhou province is discovered recently in Zunyi, Guizhou province. Basing on the measurement result of the sulphur species ,this paper analyses the characteristics of different sulphur species （sulfate sulphur,pyrite sulphur and organosulphur） on the stratigraphic section of the lower Cambrian black shale and in the ores from the deposit,and also infers the source of reduced sulphur in the Ni-Mo sulfide ore layer.
