英文摘要 | We invert for the upper-mantle temperatures of the chinese continent in the depth range of 70-240 km from a recent s-velocity model. the depth where temperatures intersect a mantle adiabat with a potential temperature of similar to 1300 degrees c is in close correspondence with the top of the seismic low velocity zone for most regions. this correspondence implies that seismic lithosphere estimated from short-time scale seismic information may be equivalent to the long-time scale geodynamical lithosphere. defining the 1300 degrees c adiabat as coinciding with the lithospheric base, we estimate the seismic-thermal lithosphere thickness. the estimated thickness shows obvious dependence on the tectonic settings. beneath eastern china, which mainly belongs to the circum-pacific tectonic domain, it has a thickness of similar to 100 km; and beneath the qinghai-tibet plateau and south to the tarim craton, which belong to the tethyan tectonic domain it has a thickness of similar to 160-220 km. the lithospheric thicknesses of the three large para-platforms/cratons range from similar to 170 km for the western yangtze, similar to 140 km for tarim, and similar to 100 km for sino-korean. the three cratons may have been reshaped by phanerozoic tectonic activities and are thinner than most cratons in other continents.
