摘要
小营盘金矿与东坪金矿皆是全国知名的大型金矿。小营盘金矿产于太古宇桑干群变质岩中，东坪金矿产于海西期碱性杂岩体中。矿床地质特征、同位素地球化学和包裹体地球化学研究显示，这２个矿床在矿物组合、成矿阶段、蚀变类型、成矿物质来源等方面具有许多相似之处，尽管二者赋矿围岩及成矿时代不同，但它们均属与碱性杂岩体有关的中温热液型金矿。
Xiaoyingpan and Dongping are two of the most important gold deposits in China. Gold mineralization of these two deposits occurs within the Archean metamophic rocks of Sanggan Group and Hercynian alkaline complex , respectively. The studies of geological characteristics, isotopic geochemistry and inclusion geochemistry on these two deposits show that they have similar mineral assemblages, ore forming stages, alteration types and ore forming mass sources. Although the host wall rocks and the metallogenetic epochs of them are different, they are both mesothermal gold deposits which related to alkaline complex.
