鲁西地区古生代非金属矿含矿沉积建造

THE PALAEOZOIC ORE-BEARING SEDIMENTARY FORMATIONS OF NONMETALLIC MINERALS IN WESTERN SHANDONG

摘要:

鲁西是山东省古生代非金属矿的重要产区。自寒武纪早期至二叠纪晚期，形成了海相－海陆交互相－陆相沉积地层及－系列非金属矿沉积建造，有：寒武纪的石英砂岩、石膏、石灰岩、泥灰岩、木鱼石等含矿沉积建造；奥陶纪的白云岩、石膏、石灰岩等合矿沉积建造；石炭纪的硬质耐火粘土、软质耐火粘土、膨胀粘土岩、高岭土等含矿沉积建造；二叠纪的膨胀粘土岩、硬质耐火粘土、石英砂岩等含矿沉积建造。这些合矿沉积建造区域分布稳定，与华北地台区内其他一些地区同类含矿沉积建造可以对比。山东古生代非金属含矿沉积建造的总结和研究，对有关非金属矿产的开发应用和普查找矿具有重要意义。

Abstract:

Western Shandong is an important area bearing palaeozoic nonmetallic minerals in Shandong province. From early Cambrian period to late Persian Period, a Sequence of strata of marine facies-paralic facies and a sequence of sedimentary formations of nonmetallic mineral were formed, including: sedimentary formation of quartzosesandstone, gypsum, limestone, marl in the Cambrian; those of dolomite, gypsum andlimestone in Ordovician; the sedimentary formatiosn of hard fireclay, soft fireclay,bentonite and kaolin ...
