摘要
安图县新合研究区位于柴达木—华北板块(Ⅲ)、华北陆块北部陆缘造山带(ⅢA)、哈兰达岭—英额岭新元古代—古生代叠覆造山亚带(ⅢA 1)中部。处于Ⅲ55吉中—延边(活动陆缘)Mo Au As Cu Zn Fe Ni W成矿带内,成矿地质条件和找矿前景较好。通过1∶1万土壤地球化学测量,对10种成矿元素进行地球化学参数特征分析,圈定综合异常13处,重点对Ht1、Ht2和Ht5异常特征进行综合分析。在此基础上,结合成矿地质条件和矿化蚀变特征,优选出找矿靶区2处。对B1号找矿靶区Au元素异常浓集中心进行工程验证,发现1条金矿化蚀变带,带内见5条金矿体,进一步证实本区具有较好的找矿前景。
The Xinhe study area in Antu County is located in the central part of Qaidam North China Plate(III),the northern margin orogenic belt of the North China Block(IIIA),and the Halandaling Ying eling Neoproterozoic Paleozoic superimposed orogenic belt(IIIA1).It is located in the III 55 Jizhong Yanbian(active continental margin)Mo Au As Cu Zn Fe Ni W metallogenic belt,with good metallogenic geological conditions and prospecting prospects.Through 1∶10000 soil geochemical survey,the geochemical parameters of 10 metallogenic elements are analyzed,and 13 comprehensive anomalies are delineated,focusing on the comprehensive analysis of Ht1,Ht2 and Ht5 anomalies.On this basis,combined with metallogenic geological conditions and mineralization alteration characteristics,two prospecting target areas are optimized.The engineering verification of the gold element anomaly concentration center in the B1 prospecting target area is carried out.One gold mineralization alteration zone and five gold ore bodies are found in the zone,which further confirm that there is good prospecting prospect in this area.
