An integrated stratigraphic record from the Paleocene of the Chijiang Basin, Jiangxi Province (China): Implications for mammalian turnover and Asian block rotations

These new paleomagnetic results from the Chijiang Basin are also used to augment other published data and to calculate a Paleocene paleomagnetic pole for the South China Block. The new pole shows no significant vertical axis rotation compared to the Paleocene reference pole for Eurasia indicating that much of the clockwise rotation that has been documented for the South China Block from Cretaceous deposits cannot be the result of extrusion tectonics associated with the early Paleogene India-Asia collision. Observed Cretaceous rotations of the South China Block may be the result of late Cretaceous-early Paleocene rifting in the backarc of the Kula-Pacific subduction zone.
