Geological Characteristics Metallogenic Regularity and Mineral Resources Predication of Taxi Region in Chifeng of Inner Mongolia

LIAN Yongbiao;No.1 Exploration Institute of Geology and Mineral Resources;  
Through carrying out regional mineral resources survey with the scale of 1∶50000,geological characteristics Taxi area in Chifeng of Inner Mongolia has been studied comprehensively.Metallogenic regularities have been summarized,and the prospecting target areas have been circled.This area is located in Tianshan—central Inner Mongolia—Xingan geosyncline area,central geosyncline fold system in Inner Mongolia,late Variscan geosyncline fold belt in west Sunite banner,the northwest edge of Linxi syncline,and southwest edge of Da Hinggan Mountains polymetallic metallogenic belt.Permian and Jurassic strata mainly developed in this area.Regional tectonic movement is strong.It is mainly composed of brittle fractures,accompanying with folds.The main tectonic line has the trend of NE.The intrusive rocks distributed mainly with the trend of NE.It is mainly composed of late Jurassic and early Cretaceous acid and medium-acid granites.Main mental resources in this area are silver,copper,lead,zinc,tin,tungsten,iron and other metals.It can be divided into four mineralization periods,they are late Variscan period,Indosinian and early Yanshanian and late Yanshanian.Mineralization in late Yanshan period is the strongest with filling repalcement.Through comprehensive analysis,the study area has been divided into 4 metallogenic predication areas with the second level,and 4 metallogenic predictation areas with the third level.It will guide the direction of prospecting work in this area.
