英文摘要Shanzhuping deposit is located in the southwestern Zijinshan ore field, Shanghang County, Fujian Province, develops the Au, Cu and Mo elements anomaly, and forms Au and Cu deposit. The granodiorite and monzogranite are selected for carrying on petrology, petrography, whole rock geochemistry, U-Pb geochronology and Lu-Hf isotope. Here we report the monzogranite and granodiorite Pb-206/U-238 weighted mean age at 105. 2Ma and 113. 4Ma. Combined with the zircon characteristics of magma oscillation and Th/U ratios, which reveals that there are two episodes magmatic activities of Late Yanshanian. The granodiorite and monzogranite share geochemical affinities with typical island arc, enriched Na element ( Na2O/K2O > 1), light rare earth element ( LREE), large icon lithophile element ( LIEE, such as Ba and K), and U, Th and Pb etc., depleted high field strength element ( HESE, such as Nb, Ta and Zr), and characterized with peraluminous ( A/CNK with 1. 19 similar to 1.68), medium ( La/Yb) N ( 13. 6 similar to 17. 4), and high Mg-#(45. 89 similar to 48. 53); slightly negative Eu anomaly (delta Eu ranges 0. 79 to 0. 97), and slightly positive Ce anomaly ( ranges 1. 0 similar to 1.08). The peak value of zircon two -stage Hf model age (t(DM2)) ranges of 1.05 similar to 1. 10Ga and 0.95 similar to 1. OGa, the epsilon(Hf)( t) ranges of -4. 47 similar to +2.38 ( mainly negative values) and -2. 73 similar to +1.47 (mainly positive values), respectively. Based on previous research results and opinions of this study, we infer that monzogranite derived from melting of Mesoproterozoic ancient basement in upper crust, while granodiorite derived from the Neoproterozoic crustal material and subjected to the contamination of mantle materials. The Shanzhuping deposit formed in Late Yanshanian island arc or active continent margin tectonic setting, which is closely related to paleoPacific plate subducted to Eurasian plate, and the southwest or south of which was predicted as two favorable exploration region.
