- Abstract
The Pb–Zn-Ag–Cu-Sn-Fe-Mo metallogenic belt in the southeastern Inner Mongolia is the most important polymetallic concentration area in China. Geologists have conducted detailed studies on typical polymetallic deposits, but the distribution feature and ore-controlling factors of the overall deposits in the study area are still unclear. In this research, geochemical and geochronological characteristics, including major and trace element analysis, zircon U–Pb dating, sulfur isotope, and magnetic data, were combined with regional geological background to explore the formation mechanism of deposits. The results show that metallogenic material source, geological structure, the Permian strata, and ore-forming materials in the wall rock and magmatic rock are the major ore-controlling factors in the southeastern Inner Mongolia. Specially, the main mineralization periods in the study area were the Late Jurassic and Early Cretaceous, and the ore-forming minerals were mainly related to the acidic magma activity. The elements in strata provided a source of minerals as well. In addition to the magmatism which plays a key role on the spatial distribution of deposits, the combined control of the regional deep faulted structural belts, the newly-born structures, and the NE-trending fold structures of the Permian strata makes the deposits present belts in the northeast, clusters in the northwest, and patches at the intersection. A systematic summary of metallogenic characteristics, combining geological background with geochemical and geochronological information, yields important practical significance for future regional prospecting.
