嘎拉山地区位于大兴安岭山脉北东端与小兴安岭山脉北西端接壤处,处于黑龙江省重要的有色金属成矿区带内。在嘎拉山地区1∶5万水系沉积物测量基础上,通过对成矿元素分布特征、相关性等分析认为区内主要成矿元素为金,后期叠加富集特征明显,金异常规模较大,峰值高,浓集中心明显,元素套合好,找寻金矿床或矿化体潜力较大;通过后期查证及地表槽探工程揭露发现金矿(点)多处,均产于北宽河岩组地层内或与侵入岩接触部位,金矿化与硅化(石英脉)关系密切,显示了研究区内具有较好的找矿前景,同时根据水系沉积物异常特征及所处地质环境,为进一步找矿工作指明了方向。
嘎拉山地區位于大興安嶺山脈北東耑與小興安嶺山脈北西耑接壤處,處于黑龍江省重要的有色金屬成礦區帶內。在嘎拉山地區1∶5萬水繫沉積物測量基礎上,通過對成礦元素分佈特徵、相關性等分析認為區內主要成礦元素為金,後期疊加富集特徵明顯,金異常規模較大,峰值高,濃集中心明顯,元素套閤好,找尋金礦床或礦化體潛力較大;通過後期查證及地錶槽探工程揭露髮現金礦(點)多處,均產于北寬河巖組地層內或與侵入巖接觸部位,金礦化與硅化(石英脈)關繫密切,顯示瞭研究區內具有較好的找礦前景,同時根據水繫沉積物異常特徵及所處地質環境,為進一步找礦工作指明瞭方嚮。

Galashan region ,lying in the northeast of Great Khingan Mountains and the northwest of Lesser Khin-gan Mountains ,is located in the important non-ferrous metallic mineral belt of Heilongjiang Province .Based on the 1∶50 000 stream sediment survey ,the paper made a preliminary analysis on geochemical features in Galashan region .The analysis,carried out about elements distribution characteristics and correlation ,etc.,indicates that the main ore-forming element is gold ,and the characteristic of superimposed enrichment is evident in late stage .The stream sediment survey showed that Au anomaly is of great scale ,and has high peak value ,obvious concentration centre and good registration . The deposit possesses great potentials in searching gold deposits and mineralization .The gold mineralization spots oc-curred in the Beikuanhe Formation or the boundary of intrusive rock according to surface engineering .The mineraliza-tion type is dominated by silicification ( quartz vein ) .It displayed great prospecting potentials , and according to the characteristics of stream sediment survey anomaly and geological environment ,provides guidance for further prospec-ting.
