大兴安岭南段白音诺尔锡多金属矿田构造控矿格局及成矿系统特征

白音诺尔锡多金属矿田位于大兴安岭南段,近年来的勘查与科研工作在白音诺尔铅锌矿的深部及外围取得了喜人的成果,深部探矿实现了资源储量翻番,外围探矿发现了哈力黑坝锡矿、腰尔压锡矿等,以往的研究多局限于白音诺尔铅锌矿区,本文以整个矿田范围为研究对象,以岩浆热液型锡多金属成矿理论为指导,对矿田构造控矿格局及成矿系统进行了研究,划分了3处成矿系统,并进行了矿化特征研究,指出了各成矿系统的成矿中心,指导矿田内的勘查评价工作,特别是对锡矿的评价具有重要的理论和实践意义。

Tectonic ore-controlling pattern and metallogenic system characteristics of the Baiyinnuoer tin polymetallic ore field in the southern of Daxinganling

The Baiyinnuoer tin metal ore field is located in the southern of Daxinganling. In recent years, exploration and scientific research have achieved gratifying results in the deep and peripheral parts of the Baiyinnuoer Lead-Zinc Mine. Deep exploration has doubled the reserves of resources and discovered the surrounding exploration. Liheoba tin mine, waist pressure tin mine, etc., the previous research is mostly limited to the Baiyinnuoer lead-zinc mine area. This paper takes the whole mine field as the research object and guides the magmatic hydrothermal type tin polymetallic mineralization theory. The ore-controlling ore-forming structure and ore-forming system of the ore field were studied. Three ore-forming systems were divided, and the mineralization characteristics were studied. The metallogenic centers of each metallogenic system were pointed out to guide the exploration and evaluation work in the ore field. Especially the evaluation of tin mine has important theoretical and practical significance.
