In order to expand reserve resources of the Qiongkuer iron deposit in Nilka County,Xinjiang, the authors conducted surface magnetic survey for 1:50000 geochemical Hs-19 anomaly.Through such means as reduction to the pole and continuation,the spatial distribution of attitude characteristics of three delineated high-magnetic anomalous bodies was detected;through two and a half dimensional interactive inversion,the buried depth and shape of the orebody were fitted;through drilling verification,the Qiongkuer iron deposit was discovered.At the late stage,a concealed orebody of certain size was found in the vegetation cover area on the western side of the main ore block according to the result of magnetic inversion,thus providing geophysical basis for the exploration of the deposit and the expansion of resource quantity.
