| 中文摘要: |
| 在大兴安岭北段额仁陶勒盖大型银矿外围东部成矿地质条件有利地区开展了地质、激电、高精磁、土壤综合剖面工作，取得了较好的找矿进展。发现了一处规模较大的连续高极化高电阻率异常带，该异常带对应叠加有多元素土壤地球化学异常，综合判断为矿致异常，结合物化探工作及地表工程验证新发现了布日罕特银多金属矿点，并圈定了矿体，判断深部矿化体具有一定规模。通过地质填图工作在额仁陶勒盖大型银矿南部新发现了钼矿化点，综合显示出额仁陶勒盖矿集区有较好的找矿远景。该区的综合地物化找矿方法为大兴安岭北段及相邻地区找矿勘查提供了范例。 |
| 英文摘要: |
| At the east of Erentaolegai large silver deposit in the North of Greater Khingan Mountains, ore search efforts have been conducted including geological survey，induced polarization measurement，high-precision magnetic and soil composite profiling. As a result, an anomaly zone was found of a large scale with continuous high- polarization and high resistivity. It is consistent with the multi-element soil geochemical anomalies, considered being caused by ore. Furthermore,Burihante silver polymetallic ore occurrences were discovered by geophysical and geochemical surveys and trench verification on the surface, and the ore body was delineated with a certain scale of mineralization at depth.Besides, a molybdenum mineralization spot was found by geological mapping at the south of the Erentaolegai large silver deposit. In summary, these findings show a good prospect of ore search in the Erentaolegai ore concentration area. This integrated application of geology, geophysics and geochemistry provides an example for prospecting in the north of the Greater Khingan Mountains and adjacent areas. |
