东昆仑茫崖河东地区地球化学钴异常与含矿地质体的响应
Response of the geochemical anomalies of cobalt to ore-bearing geological bodies in the Mangyahedong area,eastern Kunlun
摘要
Abstract
Over recent years,large-scale geochemical surveys on a scale of 1∶25,000 have been conducted in the eastern Kunlun re-gion for geological prospecting.These surveys,characterized by the rapid and accurate location of anomaly sources,have been widely applied in mineral explorations,yielding encouraging mineral prospecting results.Using 1∶25,000-scale stream sediment surveys,this study delineated 12 geochemical integrated anomalies of the element associations of Cu,Co,and Ni in the Hedong area,Mangya City,eastern Kunlun.These anomalies include one integrated anomaly dominated by Co,where various element anomalies exhibit high-degree overlap,relatively large scales,high intensity,and distinct concentration zoning.The Co anomaly is closely associated with the Ordovician Qimantag Group,demonstrating a high degree of spatial consistency.The subsequent anomaly verification reveals four cobalt mineralized zones within anomalies GA16,GA26,GA11,and GA39,with three ore bodies and multiple mineralized bodies of cobalt being identified within the mineralized zones.The comprehensive analysis indicates that the eastern Kunlun region enjoys excel-lent metallogenic geological conditions and favorable geochemical characteristics,with promising prospecting results having been a-chieved.Therefore,this region has the prospecting potential of medium to large-scale cobalt deposits.关键词
