摘要
通过对杨立掌锰矿床的杨立掌锰矿段、李家湾锰矿段矿床地质特征和钻孔地质资料综合分析,根据"大塘坡式"锰矿古天然气渗漏成矿系统与成矿理论,阐述了矿石矿物成分、结构构造在平面上的变化特征,总结矿体在平面上及沿成锰沉积小盆地短轴方向上的分布特征,并对含锰岩系厚度、矿石品位与矿体厚度三者关系进行了探讨。在此研究成果的基础上,总结杨立掌锰矿床矿体空间分布特征,指出该锰矿床北东东向深部及F1断裂北西盘的找矿方向。
By analysis the geological characters of Yanglizhang section and Lijiawan section and the drilling information of Yanglizhang manganese deposit, according to Datangpo -type manganese palaeo -gas seepage metallogenic system and metallogenic theory, the changing character of mineral component and structure on the plane are introduced, the distribution of orebody on the plane and the minor axis direction along manganese formation sedimentary basin are summarized and the relation between ore -bearing rock thickness, ore grade and orebody thickness are discussed. The spatial distribution character of Yanglizh summarized and prospecting direction in NEE deep position and NW F1 fracture of ang manganese deposit is this manganese deposit.
