Paleomagnetic, tectonic and geochronological constraints for Permian-Triassic oroclinal bending of the Mongolian collage

Abstract

The Central Asian Orogenic Belt constitutes the Kazakhstan and Mongolian oroclinal collages located between the Tarim-North China collage to the south and the Siberian craton to the north. While the oroclinal bending of the western Kazakhstan collage is widely accepted by the paleomagnetic and tectonic community, the oroclinal bending model of the eastern Mongolian collage is disputed.

Here we presented several arguments to constrain forPermian-Triassic oroclinal bending of the Mongolian collage.
