The Characteristics and Development of the Permian Reefs in Ziyun County,South Guizhou,China
- Rev Recd Date: 1995-02-08
Abstract: The Pemian reefs in Ziyun County,Guizhou, are among the best developed reefs in South China. The horizon of these reefs ranges from the Middle Permian Maokun to the uppermost Permian Changxingian. Except the Upper Permian Wujiapingian coral biostromes, the main reef building organisms include calcisponges, hydrozoans, blyozoans, and the enerusting alga Archaeolithoporella. The facies difference is very distinct. Especially the Changxingian reef complex,including backreef skeletal sand facies, reefcore facies, forereef slope facies, and basin f acies, can be observed in a distance less than fi kilometers from north to south. Well de-veloped reefs exist in the highstand systems tracts of each depositional sequence. Relative changes of sealevel and paleoclimate are believed to be the fundamental control factors on the development of the reefs.
