AbstractThe Gaoshanhe Group is one of the oldest sedimentary strata overlain the Xiong er volcanic province along the southern margin of the North China Craton (NCC), with abundant Mesoproterozoic depositional records. In this paper, sedimentary tuff and quartz sandstone samples are selected from the bottom to the top to study in detrital zircon U-Pb age, lithogeochemisty and Nd isotopic composition. Detrital zircons from the bottom sedimentary tuff yield a distinct age peak of 2309 +/- 3Ma(MSWD = 3. 2,N = 63), showing a close relationship with the global magmatic shutdown period. These tuff have epsilon(Nd) (t = 1700Ma) = 13. 2 similar to -3. 8 and the corresponding /Dm'. ages are from 2. 51Ga to 3. 26Ga, which resemble that of the Xiong' er volcanics, suggesting the Archean crust contributed much to their both magma source. Notably, the maturity is reduced when sandstone layer deposit upwards, meaning materials from sedimentary recirculation is less. The eNd (t) values are varying from 11. 9 8. 3 to 0. 8 +0. 5 and to 8. 2 2. 4, corresponding with the dominate age peaks from 1850 2100Ma to 2200 similar to 2300Ma and to 2500Ma. The multi-source are involved from enrichment to weak deplete and to enrichment, also resulted from component differentiation. The youngest concordant zircon grains are concentrated among 1760 1770Ma and the overlain Guandaokou Group has been constrained younger than 1600 similar to 1610Ma, implicating the Gaoshanhe Group should be a part of the "Changcheng" System in the southern margin of the NCC. Zircon grains of the Gaoshanhe quartz sandstones are from mid-late Paleoproterozoic 1800 similar to 1900Ma, 1950 similar to 2100Ma, 2200 similar to 2350Ma and Neoarchean 2500Ma, 2600 similar to 2700Ma, in accordance with the material source of the Changcheng System in Yanliao area, suggesting they should be comparative in sequence stratigraphy.
