Abstract:polymetallic deposit in inner Mongolia is located within Tianshan—Xinmeng Orogenic system,in Daxing’anling arc—basin system in
hierarchy II tectonic unit and in Linxi—Wulanhaote island—arc zone in hierarchy III tectonic unit.It also lies in Tuquan—Linxihualixi Yanshanian

Seven minerlaization—alteration zones are marked.Geochemical anomalies are found in Au—Ag—Cu—Pb—Zn—Sn—Mo—As—Sb elements via
1:10000 soil geochemical survey with four composed anomalies,especially in Ag—Zn—Pb anomalies with clear concentration centers.No.III and
N0.V zones are closed to geochemical anomalies.PE profile is a typical low-resistance-high-polarization。well consistent with geochemical
anomaly AP2,which is produced by mineralization as confirmed by drilling.
The mineralization—alteration zone,which is mainly controlled by NE—striking faults,of which No.III and No.V zones are located in the
conjection between EW—and SN—striking faults.Metallic mineralization occurs in the lower Permina or the upper Jursasic Manketou’ebo
formation,most associated wiht Mesozoic(1ate Yanshanian period)magmatic activiites.
