摘要
宜昌黄花场下奥陶统可划分为流水成。的颗粒岩，生物成因的礁灰岩，生物化学成回的叠层石灰岩。复合成因的白云岩、泥灰岩及页岩等４大类１４种岩相。它们形成了局限台地相、开阔台地相、台地滩相、台地礁相、浅海陆棚相等５种岩相组合。从下向上有规律地形成了２种岩相序列，即碳酸盐岩台地岩相序列和沉没台地岩相序列。
The Early Ordovician at Huanghuachang,Yichang can be classified into four group lithofacies: water current genetic grainstone ; biogenic reef limestone; biochemical genetic stromatolithic limestone;polygenetic micrltic dolostone;marl and shale. These lithofacies consist offive kinds of lithofacies asso(ations: restricted platform,open platform, platform shoal,platform reef, neritic shelf factes associations. They constitute two lithofacies sequences in ascending order:carbonate rock platform lithofacies sequence and subsided platform lithofaciessequence.
