摘　　要：通过地质勘查和综合研究工作,在青海柴北缘新发现了一个中型规模的金矿床--青山金矿。青山金矿位于柴北缘赛什腾山-阿尔茨托山造山亚带,是滩间山地区继金龙沟金矿床、细晶沟金矿床、青龙沟金矿床之后发现的又一处具有较好找矿潜力的矿床。根据野外地质工作,结合室内综合研究,讨论了青山金矿床的矿床地质特征、控矿因素。青山金矿属于中-低温热液构造破碎带型金矿床。通过青山金矿的发现,证明柴北缘地区仍具有良好的寻找构造蚀变岩型金矿的前景。A medium-sized gold deposit-the Qingshan gold deposit was discovered in northern Qaidam in Qinghai through geological exploration and comprehensive research work. This deposit is located in the Saisiteng Shan-Aerzituoshan orogenic subzone of North Qaidam,which is another gold deposit with good prospecting potential after the Jinlonggou gold deposit,the Xijinggou gold deposit and the Qinglonggou gold deposit in the Tanjianshan area. Based on field geological work and comprehensive studies,the geological characteristics and ore-controlling factors of the Qingshan gold deposit were analyzed. The Qingshan gold deposit belongs to the middle-low temperature hydrothermal structural fracture zone type gold deposit. The discovery of the Qingshan gold deposit proves that the northern margin of Qaidam still has good prospects for prospecting structural altered rock type gold deposits.
