摘　　要：340高地位于黑河市西北约50km的北大沟附近,是1997年1∶50 000化探和2000~2003年1∶20 000化探逐级筛选出来的。2008~2009年优选了2km^2重点异常部位重新开展1∶20 000的土壤地球化学测量和1∶10 000激电中梯测量工作,圈定异常后对重点异常地段进行加密激电剖面测量(50m×5m)和异常查证工作,发现了1条金矿体。对发现的矿体进行物探、槽探、钻探等手段查证,取得较好的找矿效果,为研究区进一步寻找金矿提供了依据。340 highland near the Beidagou is located about 50 km northwest of Heihe City, it was screened out by 1 ： 50 000 geochemical exploration in 1997 and 1：20 000 geochemical exploration in 2002-2003 step by step. It is preferable to reconstruct the geochemical soil survey of 1 ： 20 000 and the 1 ： 10 000 IP Intermidiate Gradient Survey in the 2 km2 key anomalous parts in 2008 -2009. After delineating excep- tion, the abnormal sections of the thermal section measurement of the encryption work （50 m × 5 m） were focused on and inspected the anomaly, a gold ore body was found. Geophysical exploration, trenching, drilling and other means were used to verify the discovered ore body, a better prospecting effect has provid ed the basis for further finding gold ore.
