大兴安岭南段火山构造与成矿作用探讨

THE VOLCANIC STRUCTURE AND A PROBE INTO THE METALOGENESIS OFDAXINGANLING MOUNTAINS S SECTION

区域地质构造复杂,断裂构造发育,岩浆活动极其强烈,各类地球化学异常,以及所发现的矿点、矿化点大多沿北西向断裂控制的火山颈相为中心呈环状分布。这至少表明大兴安岭南段成矿带铁、铜多金属成矿受中生代火山机构控制。

In this area,the regional geological structure is complicated,fault developed,magmatism very intense.The various geochemical anomaly and the discovered ore occurrence mostly distributed all make the ring around the volcanic stump facies centre controlled by NW fault,which show at least the Fe,Cu multimetallic metallogenesis is controlled by Mesozoic volcanic mechanism in S section metallogenetic zone of Daxinganling mountains.
