摘　　要：青海省都兰县多龙恰柔北山地区为高海拔山区,自然条件较恶劣,矿产勘查工作起步较晚。通过对本区地质资料的综合分析及踏勘工作,得出本区中酸性岩分布广泛、构造活动强烈、蚀变带发育,是成矿的极有利条件。为了进一步确定多龙恰柔北山地区成矿地质条件,在区内进行了地质填图、化探、槽探工作,圈定了20个多元素综合异常以及多处矿化点、蚀变带,得出BS5、BS11化探异常有较好的找矿前景,为下一步地质工作提供依据。Duolongqiarou Beishan area is a mountainous area with high altitude,poor natural condi⁃tions and late start of mineral exploration.Through comprehensive analysis and exploration of geological data in this area,it is believed that the widespread distribution of acidic rocks,strong tectonic activity,and de⁃veloped alteration zones are extremely favorable conditions for mineralization.In order to further determine the ore-forming geological conditions in the Duolongqiarou Beishan area,geological mapping,geochemical exploration,and trenching work were carried out in the area,delineating 20 multi-element comprehensive anomalies,as well as multiple mineralization points and alteration zones.It is believed that the BS5 and BS11 geochemical anomalies have good prospecting prospects,and based on this,the next geological work will be carried out.
