Moreover, strong anisotropy is observed in the north and southcentral Tien Shan. Fast Pn velocity in the southcentral Tien Shan is nearly in NS directions, which is consistent with the SKS wave anisotropy concerning mantle flow. However, fast Pn velocity directions in the northcentral Tien Shan show a southward rotation variation. We estimate that it is probably related to the inserting of the crust of the Chu basin from the southern Kazakhstan platform to the central Tien Shan, which caused a change of stress fields and lithosphere deformation.
