摘要
黑龙江省嫩江县嘎拉山、福草山地区位于小兴安岭山脉北端，为典型的森林沼泽一冻土景观区。由于该区沼泽密布、地表覆盖较厚，地质工作难度较大，因此找矿工作一直没有大的突破。武警黄金部队于2007～2008年采用化探方法在该地区开展了岩金找矿工作，圈出了多个地球化学异常。其中水系HS—Au-15号异常规模大、浓集中心明显、浓度分带清楚，并具有较好的异常组合特征，成矿地质条件有利。通过土壤面积性查证和槽探揭露验证工作，在该异常内发现了金矿体5条，最高品位达26．18×10^-6。说明该区具有较好的找矿前景，为岩金找矿工作指明了方向，也为下一步全面开展地质找矿工作奠定了坚实的基础。
Galashan-Fucaoshan region, lying in the northern part of Xiaoxing＇anling Mountain, is typically of forest bog and frozen earth sight. The densely distributed swarps and thick soil coverage lead to the difficulty of ore-hunting. Many anormallies are obtained from the geochemical exploration done by our party in 2007-2008, among which HS- Au-15 strean sediment anormally is with large scale, obvious concentration center, clear concentration zonation, excellent abnormal eonbination characteristics and advantageous geological conditions. By the detection of soil and trenches, 5 gold ore-bodies are discovered, with highest gold grade of 26.18 × 10^-6, which provides firm basis for the future ore-prospecting.
