| 摘 要： | 黔南布寨生物礁受同沉积断层控制,发育在开阔台地边缘,其西南部和东北部分别是台盆相和滨海相沉积区。礁主要由以层孔虫和床板珊瑚为主的群落建成。礁相可明显划分出礁前、礁核、礁翼和礁后等亚相,其中礁后亚相与邻区的生物礁有很大区别,显示它发育在比邻区礁相对较深的环境中。生物礁的发育受到海平面升降的控制,分为两个大的旋回,分别形成鸡泡段和鸡窝寨段的生物礁

| Abstract: | The Devonian Buzhai reefs in southern Guizhou developed in the Jipao and Jiwozhai members of the Dushan Formation. The reefs distributed along the boundary between the platform and platform basin and grew on a narrow elevated area, caused by a syn sedimentary fault. They were mostly frame reefs, built mainly by Stromatopora-Alveolites community, which was very important reef building communitiy, characterized by the massive stromatoporoids and various tabulate corals. Some of them were baffle reefs, built mainly by blue-green algae community, which was dominated by columnar stromatolites. The reef complex could be divided into six facies, and four subfacies could be distinguished in the reef facies. The development of reefs was largely controlled by the sea transgression and regression and included two large cycles. |
