摘　　要：青海省金矿资源丰富。在青海省矿产资源潜力研究的基础上,通过对青海省金矿成矿特征、金矿类型、控矿条件和时空分布进行分析,总结了青海省金矿成矿规律。将青海省金矿成矿划分为前寒武纪、早古生代、晚古生代—早中生代、晚中生代和新生代5个成矿期,并总结了各成矿期金矿的空间分布特征,结合主要成矿带上有代表性的金矿特征,首次建立了青海省金矿成矿系列,提出了青海省金矿今后找矿勘查部署建议。There are abundant gold resources in Qinghai Province.Based on the study ofmineral resources potential in Qinghai Province,the metallogenic characteristics,gold types,ore control conditons and spatial distribution of gold deposits in Qinghai Province were analyzed,and the metallogenic regularity of gold deposits was put forward.The gold mineralization in Qinghai Province was divided into five metallogenic periods of the Pre-Cambrian,Early Paleozoic,Late Paleozoic,Late Mesozoic and Cenozoic,and the spatial distribution features of gold deposits in each metallogenic period were summarized.Based on the characteristics of the representative gold deposits in the main metallogenic belts,the gold mineralization series in Qinghai Province was established for the first time,and suggestions for future prospecting and exploration of gold deposits inQinghai Provincewere proposed.
