摘要
在总结冷口断裂带内产出的南沟、小井沟、军屯等"长城式"金矿地质特征的基础上,从矿床的成矿物质来源、含矿热液来源、成矿物理化学环境及成矿时代等方面探讨了矿床的成因。认为"长城式"金矿是与中生代构造—岩浆活动有关,产于中元古界碳酸岩地层中的微细浸染型金矿床。
After summarizing 'Great Wall' type Nangou, Ciaojingou and Juntun gold deposits in the Lengkou fault zone, this paper discussed ore genesis from of metallogenetic source, ore-bearing fluid source, metallogenetic physicochemical environment and metallogenetic epoch. It is considered that 'Great Wall' type gold deposits are microscopic disseminated gold deposits related to Mesozoic tectonic-magmatic activity, and occur in middle Proterozoic carbonate rocks.
