摘要
通过对准北煤田临涣、宿县矿区新生界底部含水层碎屑物质结构特征研究 ,初步得出结论 ,组成该层的主要碎屑物质的结构成熟度较低 ,石英砂粒具有贝壳状断口 ,锯齿状棱脊、撞击痕及溶蚀和沉淀等表面结构特征 。
WT5BZ]Studied clastic substance structural characteristic of the water horizon in the lowermost part of the Cenozoic strata in Xuxian and Linhuan mining districts in Huaibei coalfield, the author owe that structural maturity of main clastic substance in layer was lower, Quartz sand assumed surface structural characteristic of conchoidal fracture、hackly、rib、percussion scar、corrosion and precipitation. It show that sedimentary characteristic is intense physcical weathering of the source rocks、short distance and faster transport. [WT5HZ]
