The results show that the trace elements of mudstone samples from Tangjiatun Formation have the characteristics of high Th,V and Cu,but low Ba,Nb and Sr. The rare earth elements are characterized by significantly light and heavy rare earth elements differentiation,relative enrichment of light rare earth elements,and a negative anomaly of δEu. The Tangjiatun Formation belongs to a marine and delta sedimentary environment,and its tectonic setting is considered as a continental island arc environment.展开更多

The mechanism stated gives an insight into global tectonics of plates with the indirect participation of emanation streams which, in their turn, are the derivatives of centrifugal and inertial forces of planetary motion. The application of this mechanism provides a logical explanation for the regularities of global tectogenesis including the formation of mountain ridges mainly of submeridional and sublatitudinal strike, and also the drift of continental plates from the east to the west and from the south to the north. The mechanism clarifies the significance of the Arctic and the Antarctic Circles as geodynamic barriers.展开更多
