SUMMARY The Jiaodong Peninsula consists of the Jiaobei massif and the Northern Sulu UHP massif. These are separated by the Wulian suture zone (WSZ), a key region for understanding the collision between the North China Craton (NCC) and South China Block (SCB). To interpret this collisional zone, a broad-band seismic profile of 20 stations was installed across the WSZ. Shear wave splitting analysis of teleseismic data revealed a contrast in the splitting patterns beneath different structural zones of the Jiaodong Peninsula. The anisotropic structures of the Jiaobei massif and Northern Sulu UHP massif can be explained by a single anisotropic layer model with WNW-ESE or E-W oriented fast directions. In the WSZ, splitting parameters exhibit pronounced variation in backazimuths indicating a two-layer anisotropy pattern. The lower layer exhibits a WNW-ESE fast direction consistent with that observed in the other two regions. Because the fast direction is generally parallel to the present-day direction of Pacific plate subduction, the anisotropy most likely represents asthenospheric return flow in the big mantle wedge caused by Pacific plate subduction. The upper layer exhibits an NE fast direction, that is, parallel to faulting associated with the WSZ. The lithosphere may preserve fossilized anisotropy induced by the Late Triassic collision of the NCC and SCB even after subsequent destruction and thinning from the Late Mesozoic to Cenozoic. We infer that the WSZ represents a lithospheric-scale structural boundary between the NCC and SCB.
