| The Daolundaba copper and polymetallic deposit in Xiwuqi, Inner Mongoli is a medium-sized deposit which taking Cu as primary mine associated with W, Sn, Ag and other metallic mineral. From the point of view on the geotectonic location, it's on the junctions of Siberian Block, North China Block and Songliao Block which separatly locate by its north, south and east, in the interspace of this three oldland block, there is a Variscan fold bend of NE-NNE strike in which the xilinhaote mirco block located ,the Daolundaba copper and polymetallic ore zone is on the north edge of it.Based on the former research achievements, the author took a further geological and geophysical ore-prospect work on the assured target zone, through the analysis in the background and the environment of the ore-forming, the collective of the former information and achievements in geological, geophysical, geochemistry and RS of the ore zone and the investigate of geologica characteristic in strata, structure, magmatic rock and metallization of the deposit, we basically found out the occurrence, tenor, magnitude, the variation characteristics of the deep mineralization and the law of the element enrichment of the ore body, at the same time, we did aLocation prognosis by the EH4 bi-frequency induced polarization instrument.Through the profound acquaintance of the clue for prospecting, regulation of mineralization concentration, metallotect and ore-forming rules, in this thesis ,the author considers that the qianjinchang rockmass is the primary source of ore-forming which not only offers the related substances of orebody but also supplies the power and the thermal which be needed when ore came to be; the zone of contact with the rockmass and the wall rock and the NE-strike fault co-control the output of the orebody. Meanwhile, applying the method of Metallogenetic Geological Conditions analogy and the Synthetic Ore Prospecting, 2 ore-finding prospect has been blocked out.
