摘　　要：本文以板块构造理论分析和恢复了西秦岭大地构造的演化特点；以西秦岭层控金矿床区域地质构造演化研究为前提，系统研究了西秦岭地区金成矿带与裂陷活动的关系。进而从宏观上论述了研究区成矿地质背景，提出西秦岭地区三个金成矿带与古生代以来的三次裂陷活动有关。这一认识无疑对该区金矿研究与找矿提供了一个新的方向与思路。With the theory of plate tectonics, the geotectonic evolution of western Qinling has beenanalyzed and recovered. On the premise of studying on geotectonic evolution of strataboundgold deposits, the authors discussed that the geotectonic evolution specializes to the mainmineralization and that the metallogenic setting and metallogenic condition are revealedoverall. Therefore the authors propose at first time that the three metallogenic zones of golddeposits in this region are relative to rift activity. This idea may open a new thinking for thestudying and prospecting of the gold deposits in western Qinling.
