摘　　要：西秦岭地区是中国最重要的金矿集中区之一,矿床类型多样,品位普遍较高,迄今为止已发现金矿床(点)两百多个,已探明黄金储量高达千余吨。故西秦岭地区有巨大的资源潜力,找矿经济效益丰厚。本文以西秦岭的隆升历史和剥蚀深度作为研究的突破口,以其对金矿保存和探究意义的角度为切入点,采用磷灰石裂变径迹的低温年代学方法定量地限定西秦岭的隆升剥蚀。为金矿成因、区域成矿规律总结和远景成矿预测提供重要理论依据,进而指导金矿的勘探和开采。The west Qinling area is one of the most important gold concentration areas in China.There are various types of Au deposits with high grade.So far,more than 200 Au deposits(spots)have been found,and the proven gold reserves are up to more than 1000 tons.Therefore,the west Qinling area has great Au resource potential and abundant economic benefits.This paper has a discussion on uplift history and denudation depth of the west Qinling Mountains which is of great significance to preservation and exploration of Au deposits.A new technique and method,low temperature chronology method of apatite fission track,is used for quantitatively dating the uplift and denudation of the west Qinling Mountains.It provides an important theoretical basis for the study of ore genesis,regional metallogeny and metallogenic prediction as well as exploration and mining of the Au deposits.
