Development Characteristics and Geological Significance of Carbonate Tempestites in China

The domestic and abroad research on tempestites since 1960s to 70s indicates that the study of tempestites are of great importance in paleogeography and paleotectonic.In this paper,research histories of tempestites between domestic and abroad are compared,research achievements in carbonate tempestites of China in the past thirty years are summarized systematically,and several geological significances are demonstrated.Carbonate tempestites are distributed widely in 20 provinces and 3 directly governed city regions of China,mainly from Mid-Proterozoic to Triassic with double peak feature stratigraphically.And the complete depositional sequences from bottom to top are composed of: A-erosional base and conglomerates,B-graded bedding,C-parallel lamination,D-hummocky cross-stratification(HCS),E1-distal storm turbidite,E2-mudstone or micrite limestone with horizontal bedding.Among these,sections A and D are the most distinct and powerful evidences.It has been found that the paleogeographic environment controls the distribution of tempestites,by analyzing the distribution of tempestites and the evolution of paleogeologic history.Based on the above research,the carbonate depositional model of tempestites in China is concluded.At last,the significances of paleolatitude and paleoplate evolution,paleogeographic,geological isochronic and hydrocarbon and mineral resources are discussed,looking forward to giving some help to further research on carbonate tempestites in China.
