Community Structure and Paleoecology of Paleogene Lacustrine Cladosiphonia Reefs in the Dongying Depression, Shandong Province, China
摘要
Most fossil reefs found so far are preserved in marine sediments with high biodiversity of reef-building organisms and recognized as implication for shallow normal marine environment. Large amount of fibrous calcite cement was formed as the product of early diagenesis around the Cladosiphonia, reinforcing the solidity of reef structure. Cladosiphonia-build reefs undoubtedly facilitates the understanding of the palaeoecology of ancient lacustrine and the condition of paleoclimate, and is of great importance to the study of petroleum reservoir as well.
