摘要
雅满苏铁矿矿体的空间分布受成矿期断裂构造的控制,呈透镜状、舒缓波状延伸,分3个层位产出。铁矿的形成与火山热液活动关系密切,矿体中既有热液活动的特征又有矿质流体贯入的特征,早期热液活动形成交代充填型矿石,后期富铁流体贯入充填后形成品位较高的磁铁矿体。
Spatial distribution of ore bodies in Yamansu Fe deposit is controled by fractures that formed during ore formation. They occur as lens in three horizons and extend undulatedly. The ore-formation is closely related to volcanic hydrothermal activities, ore bodies are characterized both by the hydrothermal fluid flow and injection. The earlier hydrothermal activity resulted in the replacement ore and the later iron-rich fluid injected as infilling higher grade magnetite ore.
