| 摘 要： | 湘东北普乐及横洞原生钴矿床均赋存于长平断裂带F2主干断裂下盘构造热液蚀变岩带中。区域性长平断裂带为岩浆侵入和成矿物质运移提供了通道和空间；燕山期中酸性岩浆侵入为成矿提供了物质和动热来源；F2下盘层间裂隙群是重要的容矿构造；脆性围岩则是赋矿层位。

| Abstract: | Original Co-deposits of Pule and Hengdong in northeast Hunan occurred in tectonic, hydrothermal, altered rock zone of the lower plate of main fracture belt F2, Changping fracture zone. Regional Changping fracture zone supplied the space and channels for metallogenic materials transportation and magma invasion; medium-acidic magma intrusion of Yenshan Stage provided metallogenic materials and dynamothermal sources; crack groups between beds of lower plate F2 were important structures containing ores; fragile mother rock were the ore-bearing horizon. |
