| 英文摘要 | The Liangcheng area is located in the central-north of the North China Craton (NCC), easternmost portion of the khondalite belt, in which voluminous Paleoproterozoic meta-granites are exposed and can be divided into three groups of monzogranite (I), anatectic granite (II) and charnockite (III) in terms of geology and mineralogy. Our focus is on the Group I which is dominated by mineral assemblages of plagioclase, K-feldspar, quartz, biotite, and garnet. In terms of mineral assemblages and geology, they are distinctive from the ca. 1.93Ga anatectic granites (Group II) which were generated by partial melting of the khondalite. LA-ICP-MS zircon U-Pb dating showed that the Group I were emplaced approximately similar to 2.0Ga ago and metamorphosed at 1.95 similar to 1.90Ga ago, with magmatic zircons being crystallized at 856 similar to 964 degrees C (averaged 912 degrees C) and 861 similar to 900 degrees C of the metamorphic zircons. The results indicate that the Liangcheng meta-granite (Group I), together with wall rocks of the khondalite series, were metamorphosed at 1.95 similar to 1.90Ga ago, under ultra-high temperature. In situ Lu-Hf isotopic compositions of zircon, integrated with whole rock Nd isotopes and geochemistry, suggest that the Liangcheng 2.0Ga meta-granite was not S-type granite and dominantly generated by partial melting of the Archean and Paleoproterozoic lower crust. |
