论黑龙江右岸北西向构造带的确立及其对成矿的控制作用

从小兴安岭特殊的盆岭构造地貌景观、复杂的构造交叉、多期北西向及南北向成矿构造的继承延续、中生代花岗岩带和火山岩带对成矿的控制、北西向独特的地球物理异常构造趋势等客观存在的特征，确立了黑龙江右岸北西向构造-成矿带的存在.通过大量矿床实例论述了多期活动的北西向构造带具有控岩、控矿、导矿、容矿的多项成矿功能，矿床（体）呈北西向带状分布.矿床的展布具有明显的水平分带现象.为黑龙江右岸找矿预测提供了理论依据.

CONFIRMATION OF THE NW-TRENDING TECTONIC BELT ON THE RIGHT BANK OF HEILONGJIANG RIVER AND ITS CONTROL ON MINERALIZATION

Based on the special geomorphology of basin-ridge structure, complex structural intersection, inheritance and continuity of multi-stage NW- and N-S-trending ore-forming structures, the control of Mesozoic granite belt and volcanic rock zone on mineralization and the unique structural trend of NW-runing geophysical anomaly, the authors confirm the existence of NW-trending tectonic-metallogenic belt on the right bank of Heilongjiang River. Many deposit examples indicate that the multi-stage NW-trending tectonic belt has several metallogenic functions like rock-controlling, ore-controlling, ore guide and host. The horizontal zonation of deposits/orebodies is obvious, which provides theoretical basis for exploration prediction on the right bank of Heilongjiang River.
