metallogenic province

The new concept of the"Derbugan metallogenic province"is proposed instead of the"Derbugan metallo-genic belt".

得尔布干成矿区位于蒙古-额霍茨克断裂与得尔布干断裂之间,可划分3个成矿亚区:①上黑龙江(拗陷)成矿亚区,位于得尔布干成矿区北部,以金矿化为主,铜次之,可划分出3个E-W向成矿带;②额尔古纳(隆起)成矿亚区,位于中部,以铅锌银、金矿化为主,铜矿化次之,可划分出3个NE向成矿带;③克鲁伦(半拗、半隆)成矿亚区,位于南部,以铜、银、铅锌矿化为主,金矿化次之,可划分2个NW向成矿带和1个NE向成矿带。
