摘　　要：目的探讨秦岭造山带加里东期、印支期和燕山期的几个关键成矿地质事件对秦岭造山过程的响应及其发生的动力学背景。方法以秦岭造山带造山过程与成矿作用演化存在时空耦合关系为线索,研究秦岭造山带成矿事件对其不同时期地质事件的响应。结果秦岭造山带存在加里东期、印支期和燕山期的几个关键成矿地质事件。结论秦岭造山带在其形成和演化过程中存在多期构造复合活动,地质流体和成矿物质汇聚,具有优越的成矿地质条件和找矿前景。Aim To take the Tongyu Cu deposit, Wenquan Mo deposit and Jinduicheng Mo deposit as the examples for the discussions of the key metallogenetic events and their geodynamic background, responsing to the formation of the Qinling Orogeny during the Caledonian, Indosinan and Yanshanian periods. Methods There is time and space coupling relation between the formation of deposits responding to to geological events Qinling orogenand the mineralization evolvement , so the study of the ore can provide good clues for discussin time and space coupling relation between the formation of Qinling orogenand the mineralization evolvement. Results There are the key metallogenetic events during the Caledonian, Indosinan and Yanshanian periods in the Qinling Orogeny. Conclusion The multistage tectonic activity during the formation and evolvement of the Qinling Orogeny will accelerate the sink of the materials and fluids, and will bring up good geological condition and favorable area for mineralization in the Qinling orogenic belt.
