摘要
上黑龙江成矿带是我国重要的金属成矿带之一,是武警黄金第三支队当前重点的金矿地质勘查区,通过对区域成矿地质背景和成矿时代演化规律的研究,划分出中侏罗世中温热液型金矿床、晚侏罗—早白垩世火山岩型金矿床、晚侏罗—早白垩世斑岩型铜—金—银矿床3个成矿系列,将上黑龙江成矿带进一步划分成了老沟—依西肯金—铜—钼、长缨金、二十一站—宝兴沟铜—金、富拉罕金4个Ⅳ级成矿带,总结了成矿规律及找矿标志,对该区进一步地质找矿,具有一定的指导意义。
Upper Heilongjiang mineralization belt is one of our country important metal mineralization belts,is my crew current key gold ore geology investigation area,through to the area in the region mineralization geology background and the metallogenetic epoch evolution rule’s research,divides the middle Jurassic epoch warm up the fluid Au ore deposit,late Jurassic-early chalk epoch volcano lithotype Au ore deposit,late Jurassic-early chalk epoch porphyry Cu-Au-Ag ore deposit to three mineralization series,Upper Heilongjiang mineralization belt is divided into the Laogou-Yixiken Au-Cu-Mo,changying Au,21 stand-Baoxinggou Cu-Au,Fulahai Au to four of the Ⅳ-class level mineralization belts,summarize the mineralization rule and the prospecting symbol,for further carries on the geological prospecting in this area,has certain guiding sense.
