A vanadium-bearing titanomagnetite deposit with low grade��shallow occurrence and large scale has been found in Alatan Gol of Xiwuqi��Inner Mongolia�� The main ore-bearing intrusion is composed of gabbro and minor diorite��evjite��olivine gabbro��etc�� The core petrography of drills showed that the olivine gabbro with high basic degree always occurred in the middle and low section of ore-bearing rock��whereas the diorite with low basic degree in the upper and margin section of ore-bearing intrusion�� The main ore mineral includes magnetite��coulsonite�� titanomagnetite��pyrite��chalcopyrite and a little amount of rutile�� Among them��magnetite��coulsonite and titanomagnetite were distributed among silicate minerals in spongy aerosiderite��dissemination and scattered star shapes�� The structural characteristics are typical magma liquation and crystallization differentiation��which are similar to of the Panzhihua iron deposit in Sichuan�� Compared with traditional magmatic deposits��the high-grade ore body of Alatan Gol deposit currently found in the upper intrusion and there widely developed alteration in country rock�� The conclusion can be drawn that the superposition of later hydrothermal played an important role to the formation and rebuilding of the present deposit��
