新疆维吾尔自治区哈密东戈壁钼矿床是我国最新发现的特大型斑岩型钼矿床。通过分析该矿床的发现过程,总结出以下认识：1）大地构造方面,矿床位于区域构造分区的边缘,区域深大断裂所限制的断块是成矿有利的构造场所;2）区域重力、航磁、1/20万水系沉积物高温元素Mo、W、Sn、Bi组合异常是选择找矿靶区的基础;3）矿体赋存于石炭系干墩组浅变质碎屑岩中,与成矿有关的侵入岩为印支期（227.6±1.3 Ma）斑状（钾长）花岗岩（隐伏）;4）东戈壁钼矿床的发现,说明觉罗塔格成矿带仍具有巨大的找矿潜力;5）利用＂三位一体＂找矿模式进行了正确的选区,加之理论指导找矿并结合合理的快速评价方法是东戈壁特大型钼矿发现的关键。

East Gobi molybdenum ore deposit,which is newly discovered in Hami,Xinjiang in China,belongs to an oversize porphyry-type-molybdenum deposit in China.Based on the discovery process of this deposit,it is concluded the following results： 1） the ore deposit is geotectonicly located in the edge of the regional tectonic belt.The fault blocks limited by the regional deep faults are great metallogenic favorable places.2） The hihg-temperature elements composite anomaly of Mo,W,Sn,Bi of the regional gravity,aeromagnetic,1/200 000 stream sediment are the basis for prospecting enrichment target.3） Orebodies occur in the shallow metamorphic clastic rocks of Gandun group in Carboniferous system,and the intrusive rocks related to the mineralization are porphyritic（K.feldspar） granite（hidden） in Indo-Chinese epoch（227.6±1.3 Ma）.4） Discovery of the Eastern Gobi molybdenum deposit indicates that there is still a big prospecting potentiality in the Luojuetage metallogenic belt.5） Using the ＂trinity＂ prospecting model for selecting correct exploration area,combing with reasonable fast evaluation method is the key in the discovery of Eastern Gobi hugesize molybdenum deposit.
