鲁西地区新生代非金属矿含矿沉积建造

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

摘要:

山东省鲁西地区新生代盆地中蕴藏着丰富的非金属矿产资源，这些盆地由于其地质构造环境和演化过程的差异，而形成各具特色的非金属矿含矿建造。主要有旱第三纪的含盐类、自然硫碎屑岩－碳酸盐岩－蒸发岩沉积建造；晚第三纪的含膨润土、蓝宝石、硅藻土火山－沉积建造；第四纪的含蓝宝石、金刚石河床冲积沉积建造等。这些非金属矿含矿沉积建造控制了鲁西地区新生代非金用矿产的空间展布和成矿作用特点。因此，深入研究探索鲁西地区非金属矿含矿沉积建造的形成和时空分布特点，对有关矿产的找矿、开发具有重要意义。

Abstract:

The cenozoic basins in western Shandong are rich in nonmetallic mineral resources. Due to the differences of geotectonic environments and evolutionary processes in these basins,distinct non-metal mineral-bearing formations were formed, including detrital rockcarbonate-evaporite sedimentary formation bearing salts and native sulphur in the earlyTertiary; volcanic sedimentary formation bearing bentonite,sapphire and diatomaceous earth in the late Tertiary and alluvial sedimentary formation bearing sapphire an...
