The main water source is fracture-karst water in Middle Ordovician carbonate rocks. 主要的供水水源为中奥陶统碳酸盐类岩石中的裂隙-喀斯特水。
On the pore geometry of the Middle Carboniferous carbonate reservoir in eastern Sichuan 川东中石炭统碳酸盐储集岩的孔隙结构研究
The material source of the Carboniferous karst type bauxite in North China mainly came from the underlying Late Cambrian & Middle Ordovician carbonate rock. 华北石炭纪岩溶型铝土矿的主要物质来源为下伏的晚寒武世&中奥陶世碳酸盐岩。
The gold deposits hosted by Middle Proterozoic carbonate rocks at Western Liaoning and Eastern Hebei are new type of strata bound gold deposits, they have great resources potentialities. 辽西&冀东地区赋存于长城系上部和蓟县系下部碳酸盐岩中的层控金矿床为该区的一种具有良好找矿前景的新类型金矿床。
Starting with the fades analysis and emphatically dissecting two field sections of Jinshan and Chongyang On the Middle Yangtze Permian Carbonate Platform, a carbonate facies model has been established based on systemically studying its rock, palaeobiology and geochemistry. 从相分析着手,重点剖析京山、崇阳两条岩相剖面,系统地研究了岩石、古生物、地球化学组分及分布规律。
