| 英文摘要 | Based on the 3-d earth model, the common convert points-phase weighted stacks (ccp-pws) migration method is used to image the upper mantle discontinuities beneath northeast china (longitude 120a degrees-132a degrees; latitude 38a degrees-40a degrees) with 802 observed receiver functions. teleseismic records are obtained from 4 stations belonging to ccdsn and 19 stations belonging to passcal. a low-velocity layer has been detected at the depth of 620 km. this low-velocity layer rises to 600 km in the east of the study region close to the subducted slab. we consider that this low-velocity layer might be the accumulated oceanic crustal material delaminated from the western pacific subducted slab. additionally, we detect the obvious depression of 660 km discontinuity which was attributed to the interaction between the upper mantle and subducted slab. the maximum depth of 660 km discontinuity approaches 700 km, and 660 km discontinuity splits into multiple discontinuities in the northeast of the study region. |
