摘　　要：黑龙江小兴安岭—张广才岭地区是我国东北的一条重要的铅、锌成矿带。本文根据所发现的２５个矿床的赋矿地层、与成矿有关的花岗岩、矿化类型及其时、空分布特征，将它们划分为加里东期成矿系列和印支期成矿系列，进而又将加里东期成矿系列划分为铅、锌成矿亚系列，铁、铅、锌成矿亚系列和铅、锌、钨、锡、钼成矿亚系列。加里东期成矿系列是松嫩和佳木斯地块拼合、碰撞造山的结果；印支期成矿系列是在松辽盆地断陷和佳木斯－伊舒断裂走滑的构造条件下形成的。提出全球构造是首要的控矿因素。研究区域成矿演化不但可以为构造演化提供证据。Xiaohingganling Zhangguangcailing region is an important metallogenic belt of lead and zinc deposits in Northeast China. 25 ore deposits have so far been found in this region. Ore deposits of this region are assigned to Caledonian metallogenic series and Indosinian metallogenic series according to ore bearing strata, granites related to ore deposits mineralization type and temporal spatial distribution characteristics of ore deposits. The Caledonian series is further divided into three subseries, namely lead and zinc metallogenic subseries, lead, zinc and iron metallogenic subseries and lead, zinc , tungsten, tin and molybdenum metallogenic subseries. The Caledonian metallogenic subseries was formed in the process of collision between Songnen block and Jiamusi block and orogenic movement, whereas the Indosinian series was formed against the tectonic setting of stretching strike slipping. Tectonics is the first ore control factor. The study of metallogenic evolution is of great significanee not only for the investigation of tectonic evolution but also for the search and prognosis of ore deposits.
