摘要
上黑龙江盆地火山岩主要为基性、中酸性的熔岩、火山碎屑岩,可划分5个火山岩带。即:二十八站-二十七站火山岩带、二十五站-马伦火山岩带、长缨-二十五站火山岩带、图强-盘古-蒙克山火山岩带和二十一站-蒙克山火山岩带,发现有马大尔、奥拉奇、页索库等岩金矿(化)点。成矿作用与多期次的构造、岩浆活动密切相关,与火山构造相伴生的次级断裂、裂隙为导矿、容矿构造。
On Heilongjiang basin volcanic rock mainly for basic,acidic lava,pyroclastic rocks,may divide 5 volcanic rock belts.Namely： 28 stand 10-20 seven station volcanic rock belt,25 to stand a Marron volcanic rock belt,the long ribbon 10-20 five station volcanic rock belt,to plan to be stronger a Pan Gu Munk forest fire in the mountains precipice belt and 21 stands a Munk forest fire in the mountains precipice belt,discovered that has Ma Daer,Austria Rudge,the page rope storehouse isolith gold ore the spot.Mineralization and many phase of time structures,magmatic activity close related,with the volcano tectofacies associated secondary break,the crevasse to lead the ore,to accommodate the ore structure.
