发育于黔南地区的扁坪—岩板寨晚石炭世旋回珊瑚礁由3个旋回组成,每个旋回都具有较高的生物含量和生物多样性。根据生物的丰度和功能可识别出叶状藻-＂不明管状物＂群落、Ivanovia cf.manchurica群落、Tubiphytes群落和Fomitchevella群落。旋回珊瑚礁的演化过程可划分为6个阶段。分析表明,礁体形成过程中曾一度出现了高能的环境,第二、三旋回经历了迅速的环境变化。
髮育于黔南地區的扁坪—巖闆寨晚石炭世鏇迴珊瑚礁由3箇鏇迴組成,每箇鏇迴都具有較高的生物含量和生物多樣性。根據生物的豐度和功能可識彆齣葉狀藻-＂不明管狀物＂群落、Ivanovia cf.manchurica群落、Tubiphytes群落和Fomitchevella群落。鏇迴珊瑚礁的縯化過程可劃分為6箇階段。分析錶明,礁體形成過程中曾一度齣現瞭高能的環境,第二、三鏇迴經歷瞭迅速的環境變化。

Bianping-Yanbanzhai Carboniferous cycling reef in Southern Guizhou Province is composed of 3 cycles,in which the amount and the diversity of the organisms are both high.According to the abundance and features of the organisms,phylloid algae-"the undefined tube" community,Ivanovia cf.manchurica community,Tubiphytes community and Fomitchevella community are recognized.The reef-building process could be divided into 6 stages based on the community status.Analysis shows that a high-energy condition occurs in the reef-building process and the environment change sharply during the period of the second and third cycle.
