| 英文摘要 | Based on the study of REE in Mesozoic-Cenozoic sandstones, the paper indicates that Jurassic Fanghushan and Yuantongshan Formations and Lower Cretaceous Zhougongshan Formation have SigmaREE of 157 mug (.) g(-1), delta(Ed) of 0.69 and (La/Yb)(N) of 11.1, which are similar to the Foziling and Luzhenguan Groups, and it implies that the latter may be the source rocks of the former. The Sanjianpu and Heishidu Formations have high REE concentrations ( SigmaREE = 264.8 mug g(-1), 328.2 mug (.) g(-1) respectively), high Eu anomaly (delta(Eu) = 0.57, 0.67 respectively) and lower Eu/Sm ratios (0.18 - 0.19), which differs from existent metamorphic rocks in the Dabie Mountains, so where their source rocks came from remains to be studied. The REE features of the Zhengyangguan Formation can be comparable to the Dabie complex and Luzhenguan Group, which shows that the Dabie complex had suffered unroofing in Neocene and constituted the source rocks. Mesozoic sandstones in Huainan area have lower REE concentrations (SigmaREE = 80.9 mug - g(-1)), high Eu anomaly (delta(Eu). = 0.66) and (La/Yb)(N) of 5.7, and it indicates that their source rocks may not come from the Dabie Mountains. |
