摘　　要：The Cretaceous sedimentary successions in NE China are largely incomplete as the basins are inverted and younger strata are eroded.Except for the Songliao Basin,whose depositional record has remained relatively intact,the burial record to the east was interrupted in the late Early or Late Cretaceous.There is still controversy on the possible connection between the Songliao Basin and the eastern basin group,as well as the extent of the previously suggested“pan-Sanjiang”proto-basin that covered most current eastern satellite basins.To address these questions,we studied modern river catchments of variable sizes from sediment-supplying basement highs that cover most of eastern NE China to track the intense denudation events and provenance changes through the Cretaceous.We found a great inconsistency between detrital age patterns of the modern river sands and the spatial proportions of the source units.The detrital age distributions allow to re-evaluate the basement units that are mostly composed of the Triassic–Jurassic igneous suite and some metasedimentary units with Paleozoic ages,but the contribution from Proterozoic formations is negligible.Combining the newly dated modern catchment detrital U-Pb ages,the region-wide compilation of the basement emplacement ages,and the U-Pb ages in the Cretaceous formations in NE China,we systematically refine the Cretaceous provenance history.In the Early Cretaceous,the eastern satellite basins accumulated sediments from the Lesser Xing’an range(LXR)in the west,Zhangguangcai range(ZGCR)in the south,and the Nadanhada terrane(NT)in the east.The sediment of the southern Songliao Basin derived from the North China Craton(NCC)and from ZGCR but barely from the Great Xing’an Range(GXR).The Jiamusi uplift(JU)did not provide sediments to the eastern satellite basins and the Songliao Basin.In the Late Cretaceous,the eastern satellite basins received sediments from the exhumed JU but barely from ZGCR and LXR.The Songliao Basin still accumulated the sediments from the NCC,some so
