摘要
研究区处在西秦岭东段,跨西倾山-南秦岭陆源裂谷造山带和勉略构造混杂岩带,地质构造复杂,矿产资源丰富,主要金属矿种有金、铁、钴、钒、锰、铜、镍、锌等。本次研究通过1∶5万水系沉积物测量,圈出综合异常22处,通过对HS-22综合异常查证发现了东庄金矿体,通过对该矿体的地球化学特征叙述,对该区成矿特征进行了初步总结,为该带寻找同类型矿床提供具有参考意义的资料。
The research area is located in the eastern section of the West Qinling Mountains,spanning the West Slope Mountain-South Qinling terrigenous rift orogenic belt and Mianluo tectonic melange belt,with complex geological structure and rich mineral resources,including gold,iron,cobalt,vanadium,manganese,copper,nickel,zinc and so on.In this study,22 comprehensive anomalies were identified through the 1∶50,000 stream sediment survey,and the Dongzhuang gold ore body was found through the verification of the HS-22 comprehensive anomaly.By describing the geochemical characteristics of the ore body,the paper preliminarily summarized the metallogenic characteristics of the area,providing reference data for the search for similar types of deposits in this belt.
