研究区位于西伯利亚板块与华北板块的接合部位 ,是由锡林浩特“微板块”和一系列缝合线组成。构造演化经历了两次大的“开合”运动和两期“活化”。前者为金矿提供成矿物质 ;后者使之进一步富集成矿。根据其构造演化和成矿特征 ,提出本区主要有 4类金矿床。
The study area is located at the junction of the Siberian and North China plates and consists of Xilinhot “microplate” and a series of sutures. Tectonic evolution has undergone two major “opening and closing” campaign and two “activation”. The former provides ore-forming materials for gold mines; the latter makes them further enriched for mineralization. According to its tectonic evolution and metallogenic characteristics, it is proposed that there are mainly 4 types of gold deposits in this area.
