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。
The Delbrudian fault zone controls the volcanic intrusive complex and forms a polymetallic metallogenic belt. Multiple stages of tectonic magmatic activity formed in the metallogenic belt of different sizes in different periods of intrusive rock and large area distribution of Mesozoic volcanic rocks. In the area, more than 100 gold, silver, copper and other polymetallic ore deposits have been found, and the spatial distribution of the deposit is obviously controlled by the fracture. The study shows that the Deerbugan fault zone experienced many Caledonian to Tertiary tectonic evolution accompanied by corresponding magmatism. Deep fault control regional tectonic development, secondary rupture of mineralization from the lead, mineralization. This paper starts with the tectonic ore control and analyzes the tectonic ore-controlling factors of all kinds of ore deposits in the study area. It puts forward the multi-level ore-controlling effect in the metallogenic belt, which is of guiding significance for prospecting in the northeast of China in the future.
