Basic geological features of polymetallic deposit concentration areas in Baiyinnuoer-Shuangjianzishan-Haobugao

Chinese Da Hinggan Mountains is one of the important metallogenic clusters of eastern China. It is the most representative in the area of lead and zinc-copper-molybdenum-silver-gold clusters. According to the geological and other main characteristics of the mineralization in the study area, the main polymetallic ore deposit area was divided into two metallogenic systems: the late Paleozoic-Mesozoic porphyry-hydrothermal mineralization system and Mesozoic tectonic hydrothermal metallogenic system. Types of main minerals, geological characteristics and the ore-forming genesis were further discussed. Metallogenic regularities are obtained as follows:① From the ore formation, surrounding rock of ore deposit are mainly Permian, Jurassic acidic volcanic rocks and volcanic rocks; ② From the tectonic control mine, the collapse anticline axis belt, north east and north west fault interchange is the good place of ore; ③ From the metallogenic epoch, period of indosinian and yanshanian is an important metallogenic stages; ④ From the prospecting type, the main output are volcano-intrusive complex related skarn type, porphyry type-epithermal type polymetallic deposit, other new type of ore deposits may also be found.
