摘要
鄂拉山口银多金属矿床位于鄂拉山成矿带东南端,第四系覆盖厚,沼泽发育,存在常年冻土层和碎石流,用常规物探在该区找矿效果不显著.后经大功率激电剖面测量,圈出了具一定规模的激电异常带1条,推断为矿异常,经工程验证,发现隐伏银铅锌矿(化)体多条,说明本区采用大功率激电指导找矿效果显著.
The Elashankou silver-polymetallic deposit in Qinhai Province, located in the southeast end of the Elashan metallogenic belt, is covered by thick Quaternary, with developed swamps, perennial frozen soil layer and flowing detritus. Normal geophysical techniques of exploration are not effective in this area. With high-power induced polarization survey, an IP anomaly in certain scale is delineated. It is inferred to be an ore-caused anomaly. By drilling project, several concealed Ag-Pb-Zn ore （mineralized） bodies are found, showing effective result of the application of such method in exploration in the area.
