The eastern Tienshan tectono-magmatic belt is located in Kalatage magnetic field area of high magnetic force belt in Weiya-Luobuzhuang. In this area, normal magnetic field of 200～300 nT exists and its closed magnetic anomaly corresponds to the Carboniferous quartzdiorite or hidden mafic intrusions. The high-level magnetic anomaly of Qianzishan C07-2 is up to 2340 nT, where three layers of low grade copper-bearing titanomagnetite, with total thickness of 119 m, are found by drilling. Geochemical analyses of the 81 copper-bearing titanomagnetite samples show that the Fetotal varies from 3.6% to 28.80%, with an average of 13.5%. And the TiO2 ranges from 1.31% to 2.33%. In the layer of ZK0701-10/5 (111～113 m), the 2 m thick copper and magnetite bodies are observed, having CuO of 0.4% and Fetotal of 28.8%. The deep drilling verification provides strong evidences for exploring magmatic type titanomagnetite in Yuxi district of Hami.%新疆哈密东天山构造岩浆带位于尾亚-罗布庄磁力高带上的喀拉塔格磁场小区,该带发育幅值在200～300 nT的正磁场区,封闭磁异常对应于石炭纪石英闪长岩或隐伏基性侵入岩体.钳子山C07-2磁异常为该区带高磁异常,最高幅值2 340 nT.经钻探验证,打出3层低品位含铜钛磁铁矿,总厚119m.据81个化学样分析,TFe约3.6％～28.80％,平均品位13.5％,TiO2 1.31％～2.33％.ZK0701-10/5层(111～113 m)见有2m厚具工业品位的铜矿体和磁铁矿体,分析结果为Cu 0.4％,TFe 28.8％.该钻探成果为在哈密玉西地区寻找岩浆型钛磁铁矿提供了有力依据.
