沽源-红山子多金属成矿带燕山成矿阶段主要控矿因素研究新进展和存在的主要问题

New progress and existing problems in the study of main ore controlling factors in the Yanshanian metallogenic stage of Guyuan hongshanzi polymetallic metallogenic belt

沽源-红山子成矿带是中国北方重要的多金属成矿带之一,位于燕辽成矿带与大兴安岭成矿带南段的交叠部位。目前已发现大官厂、张麻井、红山子等多金属矿床及众多矿化异常点,且矿床大多以火山岩型的多金属矿床为主。本文根据前人的研究成果,主要从沽源-红山子多金属成矿带基础地质的角度对地质特征、主要控矿因素(包括岩体控矿、接触带控矿、断裂构造控矿、层位及岩性控矿)、成矿模式等研究现状进行讨论,归纳总结前人研究,并提出所存在的问题。

The Guyuan-Hongshanzi metallogenic belt is one of the most important polymetallic metallogenic belt in North China.It is located at the intersection of the Yanliao metallogenic belt and the southern section of the Daxinganling metallogenic belt.At present,Daguanchang,Zhangmajing,and Hongshanzi polymetallic deposits and many polymetallic mineralization anomalies have been found,and most of the polymetallic deposits are volcanic type polymetallic deposits.According to the research achievements of predecessors,this article mainly from the source of the Guyuan-Hongshanzi metallogenic belt in terms of basic geological characteristics,the main ore-controlling factors(including the controlling of rock mass,the contact zone controlling,ore-controlling fracture structure,strata,and lithology ore-controlling),the metallogenic model and research status are discussed and summarized predecessors'research,and the problems are put forward.
