摘　　要：青海东昆仑是中国一个重要的、极富潜力的金属成矿带,而东昆仑东段是一个以金为主的成矿聚集区。加嗡地区位于东昆仑东段督冷沟以北,从异常检查到调查评价,通过近3年的地质勘查工作,该区北部已圈出6条含金构造蚀变带,6条金矿体,多条金矿化体。通过对该区地质背景、金矿体地质特征总结梳理,综合分析地层、构造、含金构造蚀变带特征,认为金矿体形态、产状、规模受北东向构造控制明显,为构造蚀变岩型金矿;南部已发现铜矿体,结合地物化资料分析研究探讨了找矿方向,为下部工作提出建议。The Eastern Kunlun Mountains in Qinghai Province are an important and potential metallogenic belt in China,and the eastern part of the Eastern Kunlun Mountains is a gold-dominated metallogenic area.Jiaweng Area,located in the north of Dulenggou in the eastern section of the Eastern Kunlun Mountains,has seen geological exploration work in the past three years delineate six gold-bearing tectonic alteration zones,six gold ore bodies,and several gold mineralized bodies in the northern part of the area.Based on the summary of the geological background and the geological characteristics of the gold ore bodies in this area,the characteristics of strata,structures,and gold-bearing structural alteration zones are comprehensively analyzed.It is considered that the shape,occurrence,and scale of the gold ore bodies are obviously controlled by the NE trending structure and belong to the tectonic altered rock type gold deposit;copper ore bodies have been found in the south,and the prospecting direction is discussed in combination with the analysis and study of geological,geophysical,and geochemical data,and suggestions are put forward for the next work.
