| Abstract: | The Permian reefs in Ziyun County,South Guizhou,are among the well developed and excellently preserved reefs in South China.This paper deals with the cementation of these.Seven kinds of carbonate cements have been recognised.The peloidal micritic calcite,and botryoidal calcite cements are believed to have been formed in submarine diagenetic environmet and have had great contribution to the formation of the wave resistant frameworks in the reef complexes,The rod-like materials in peloidal textures sugests that the peloidal micritic calcite was related with microbials.The blocky calcite and baroque dolomite cements were formed in burrial diagenetic environment,A megative correlation between the concentration of phosphorus and δ13C in various cements have been discovered. |
