| Abstract: | New paleornagnetic data from Cenozoic rocks in Tarim enable people to revise the Phanerozoic apparent polar wandering path (APWP) of this block. This modified Tarim APWA is supported by data from other Chinese blocks. On the basis of the APWA, it is concluded that Tarim rode on a plate subducting under the Kazakhstan plate between Carboniferous and Permian time. By the Late Permian, subduction had finished. The APWP also revealed that tectonic evolution of the Tarim was characterized by northern latitudinal displacement during the Paleozoic time, while Tarim remained at relative low latitude (about 20°) until1 Cretaceous. |
