| 摘 要： | 得尔布干断裂带控制了火山 侵入杂岩作用 ,形成了多金属成矿带。多期次构造 岩浆活动 ,在成矿带内形成了不同时期规模不等的侵入岩体及大面积分布的中生代火山岩。在区内已发现金、银、铜等多金属矿产地百余处 ,矿床空间分布明显受断裂控制。研究表明 :得尔布干断裂带经历了加里东期到第三纪多期构造演化并伴有相应的岩浆活动。深断裂控制区域构造发展 ,次级断裂对成矿起导矿、容矿作用。本文从构造控矿作用入手 ,分析研究区内各类矿床的构造控矿因素 ,提出了成矿带内多级构造控矿作用 ,对今后在我国东北部找矿有一定的指导意义。

| Abstract: | Derbugan deep fracture controlled a magor zone of volcano intrusive processes and polymetal mineralization. The fracture zone has been activated for a long time from Caledonian to Tertiary period until modern time. The many stages tectono magmatic activities formed many intrusives with different epochs and scales, and large area Mesozoic volcanic rocks. We research over hundred ore deposits and/or mineraling spots in Derbugan metallogenic belt and find that deposit distribution has a close relationship with volcanic (intrusive) processes controlled by the structures. Go by studying, Derbugan fracture controlled regional structure, the secondary and studying various ore-controlled structures, this paper summarizes different scale ore-controlled structures in the metallogenic belt. It is important to guide prospecting deposits in this area in the future. |
