摘要
老挝色贡省拉芒煤矿含煤地层为石炭系上统乍奎组二段,通过地面地质调查、钻孔揭露显示,矿区无侵入岩分布,分布的喷出岩主要为华力西晚期和喜马拉雅中晚期火山活动的产物。华力西晚期岩浆活动对各主要可采煤层的影响是零星和局部的,无破坏性影响;喜马拉雅中晚期岩浆活动喷出物覆于古剥蚀面之上,对下伏石炭系含煤岩系及煤层也无影响。
Coal in Raman, Segon Province, Laos is conf＇med to the Upper Carboniferous Zhakui Formation. Hercynian and Himalayan extrusive rocks other than intrusive rock are exposed in the coal field. The extrusive rocks had no effect on the coal and coal-beating formation.
