英文摘要We report first data for the Devonian Hongshan A-type granite along the northern margin of the Precambrian North China Craton. The granite is rich in silica (SiO(2)=76.07-77.62 wt.%) and alkalis (Na(2)O + K(2)O = 8.45-8.78 wt.%), but poor in calcium (CaO = 0.28-0.70 wt%) and magnesium (MgO= 0.08-0.20 wt.%). Chondrite-normalized REE patterns for the samples from the Hongshan granite show significant negative Eu anomalies (Eu/ Eu*=0.13-0.19). They contain high Rb, Ga, Y, Nb, and Zn, but low Ba and Sr contents, and in the multi-element spider diagrams normalized to primitive mantle, they show a similar pattern to that of A-type granites, such as negative Ba, Nb, Ta, Sr, P and Ti anomalies. Geochemical plots also show an affinity with A-type granites and suggest a post-orogenic setting (A(2) type granite). SHRIMP U-Pb zircon dating yielded a concordant weighted mean (206)Pb/(238)U age of 387 +/- 4 Ma, which defines a Devonian magmatic event. The zircons have negative epsilon(Hf)(t) of -8.4 to -11.5 and give old Hf model ages of T(DM2) = 2548-2820 Ma (mean 2667 Ma). Most (176)Hf/(177)Hf and epsilon(Hf) values display Hf-isotope evolutional line of the lower continental crust. These results suggest that the Hongshan granite originated from melting of Archaean lower crust beneath the North China Craton in a post-orogenic extensional setting during the Devonian.
