摘　　要：以陕西小秦岭金矿田桐峪金矿区的两个深部探矿钻孔岩芯为研究对象,对矿田深部地层岩性构成、规模及各类岩石的Au含量进行系统研究、测试分析和规律总结,弥补矿田以往研究成果中在矿田深部地层岩性组合、各类岩石Au含量资料的欠缺,进而探讨Au元素丰度值的变化特征,为进一步完善金矿田成矿模式,助力找矿新突破,提供具有价值依据的深部地球化学背景资料。Taking into consideration the cores from two deep drill holes in the Tongyu Gold mine area of the Shaanxi Xiao-Qinling gold mine field,this study aims to systematically examine and analyze the composition,size,and gold content of various rocks in the deep orefield.The objective of this study was to enhance the metallogenic model of the gold ore field.This study addresses the lack of data concerning the lithologic assemblage and gold content in the deep part of the ore field.Furthermore,this study investigates fluctuations in the abundance of gold elements and discusses the potential implications for ore prospecting.This breakthrough will provide essential data and a solid scientific basis for future research in this field.
