| 摘 要： | 本文在野外地质工作及室内综合研究基础上,对郯-庐断裂带南段两侧金矿床的成矿地质条件作了对比,得出了它们成矿地质背景相同、均受郯-庐断裂带次级断裂控制;同属混合岩化热液型金矿床;都生成于太古界—元古界绿岩带中;金矿围岩、岩浆岩条件、围岩蚀变及成矿物质来源等均极为相似的结论,对安徽蚌埠隆起带中寻找新类型金矿具有重要意义。

| Abstract: | On the basis of field geological works and indoor synthetical study, the article have contrasted of metallogentic geological condition of gold ore-deposits in the south and on both sides of tancheng-Lukiang rift zone, then obtain following results; they have the same metallogentic geological condition and both controlled by inferior rift of Tancheng-Lukiang rift zone; they both belong to gold ore-deposit of inigmatization hydrothermal pattern; both bear in the greenstons zone of Archaean group-proterozoic group; ore rock and condition of magmatic rock and country rock alteration and origin of matallogenetic material and so on are just like, there i3 some sense in finding new pattern of gold deposits in rise zone of Baugbu Anhui. |
