摘要
论述了北峪白云岩矿的矿床地质特征及分布规律,对其控矿地质条件和成因机理进行了研究。通过开展系统的勘查工作,发现山东省蒙阴县北峪白云岩矿赋存于寒武系九龙群三山子组c段和奥陶系九龙群三山子组b段地层中,层状产出,按其层位自下而上划分为1号矿体(三山子组c段)和2号矿体(三山子组b段),二者呈上下整合接触。矿体的顶板岩石为下奥陶统三山子组a段含燧石结核白云岩,底板岩石为芙蓉统-下奥陶统炒米店组灰岩,矿体内部结构简单、厚度变化小,严格受地层层位控制,为滨海相沉积矿床。
This paper deals with geological features and forming mechanism of the Beiyu dolomitite deposit in Mengyin, Shandong. The Beiyu dolomitite deposit is confined to the Member C of the Sanshanzi Formation of the Cambrian Jiulong Group and to the Member B of the Sanshanzi Formation of the Ordovician Jiulong Group. The orebodies occur in stratified form and are conformable with wall rock and controlled by stratigraphic horizon. The deposit is a littoral sedimentary one.
