摘　　要：东乌旗地区构造复杂,岩浆活动具多期性,成矿作用与岩浆岩关系密切,形成了与华力西期、印支期、燕山期侵入岩(火山岩)有关的金及多金属矿床。通过分析区域成矿地质背景,结合近年来发现的矿床(或矿点)地质、地球物理和地球化学特征,指出了下一步工作的找矿标志及找矿方向,为矿区及外围找矿提供思路。Dongwuqi area has complicate tectonic development,multi-episodic magmatic intrusions and mineralization associated with the magmatic intrusions.Gold and polymetallic deposits in this area are hydrothermal and metasomatic deposits related to Variscan,Indosinian and Yanshan intrusions（or volcanic rocks）.Based on regional geological and metallogenic background,geological,geophysical,geochemical characteristics of deposits and ore spots in Dongwuqi area of Daxing＇anling,prospecting indicators and orientation are provided,prospecting ideas of ore district and its periphery area are also put forward.
