The Late Carboniferous Reefs Palaeoecology Characteristics of Langping,Tianlin County, Guangxi Zhuang Autonomous Region
Some Huanglong framework reefs develop in Langping,Tianlin County of Guangxi province.The size of these reefs that developed in crinoids clastic beach is generally small.Reef-building and accessory reef organism species are variety.The maturity of reef biocenoses is poor.Only a single reef-building way exists.The distribution of reefs is patchiness.Huanglong reefs in Lang Ping develop under the absence of major global skeletal reef-building animals.No obvious advantage reef-building organisms appear.Reefs are significantly affected by large-scale clastic beach in study area.A variable reef-building environment,the obvious selection preference of high-energy water and debris,not extensive distribution of consolidated and hard substrate,frequent change of water energy,crinoids flourish adapting to the environment and the not development of algae in the study area,which make the patch reefs in Langping have the typical "patch reefs in clastic beach mode" feature.Reef-building organisms ecology has an important influence to patch reefs concrete morphologies.The discovery of Late Carboniferous skeletal patch reef in clastic beach contributes to further researching ancient reef ecosystem.
