摘要
水城矿区龙潭组二段下部赋存的两层浅绿色泥岩(粘土化凝灰岩),特征显著,分布稳定。通过对其进行宏观观察、镜下鉴定、化学分析,差热分析、X 射线衍射分析等综合研究,认为它主要由火山物质在沼泽-近海湖泊里沉积而成,可以作为矿区和区域煤层对比的可靠标志层。
In the cower of the second section of Longtan formation there are two light—green mudstones(clayey tuff)with evidentfeatures and stable distribution.The combiningstudy using macroscopic and microscopic exami-nation,chemical,differeatial theamal nadX—diffraction analysis indicates that the muds-tones were formed composed of volcanicmaterials deposited in marsh and coastal larkesThe mudstones can be used as reliable markerfor seam correlation in the mining area and theregion.
