摘　　要：从礼县—白云—山阳断裂的大地构造背景及演化入手,分析了该断裂带走向上及两侧沉积环境、区域应力场的变化及产生原因;探讨了中秦岭金矿成矿物质来源;对中秦岭金成矿带、矿床(点)的分布特征,矿化类型及成矿规律进行了概括、总结。指出礼县—白云—山阳断裂对中秦岭金成矿具重要控制作用;提出了中秦岭金矿成矿模式、找矿标志等。Upon analyzing earth structure setting and evolution of LiXian Baiyun Shanyang fault,the paper analyzed the change of regional stress field and depositional environment along the fault grain and two sides,and reasons for them,discussed gold ore forming source in middle Qinlin district,summed up distribution characteristics of gold mineralization belt and ore deposit,mineralization pattern and metallogentic law.The paper holds that the fault controls gold ore forming,and proposes mineralization model and ore guide in middle QinLing region.
