Abstract:

Cambrian carbonate gravity flows in Guizhou and Hunan are various in kind.Debris flow calcirudite is the main redeposited carbonate developed on the south and north slope of the Yangtze carbonate platform.Pulsation,undulation and flow-trasformation are very common in its flow process.According to the distribution range,horizon variation andcyclic property of the calcirudite,the south margin of the Yangtze carbonate platform generally progradated southeastward from the Cambrian to Early Ordovician,and the Yangtze landmass had reached the evolution stage of matured passive continental margin.
