THE MIGRATED GEOBODIES AND THEIR PALAEOGEOGRAPHIC PROTOTYPE OF THE PERMIAN AT THE OROGENIC BELT OF THE LATE PALAEOZOIC,JILIN PROVINCE

Wen Qiongying Zhang Chuanbo Wang Xiaolin (Changchun University of Earth Science) Liu Ai Yang Baozhong (Regional geological survey, Geology and Mineral resouces Bareau, Jilin Province)  
The orogenic belt of the Late Palaeozoic in Jilin province was a part of the fold orogenic belt which belong to the system of divergence and convergence between the Siberia plate and Zhong chao plate. It was also a joint part of the circum Pacific tectonic region. By this reason its geological structure was very complex. Now the block of the rock strata were moved as a result of frequently tectonic movement. Based on the study of biostratigraphy, sedimentary geology, structural geology and geochemistry, the authers of this paper studed in detail the biogeo graphical area, lithofacies and palaeogeography. It has been for the first time found that the orogenic belts of Permian is composed of four migrated geobodies. ie, Yanbian, Jizhong, Songliao and Baicheg. According to the charaterestic of bio palaeogeography, judge of material composition and sedimentary sequence, we reconstructed the palaeolatitude and palaeotectonic history of each geobody. And finally with combination of geodynamic analysis anism, we reconstucted the prototype of tectonic palaeogeography of Early Late Permian. The basin was a complex maginal marine basin with active continental margin.
