| 英文摘要 | The Sankuanggou Fe-Cu deposit, located in northern Heilongjiang Province, is a typical skarn deposit which occurs in the NW trending Luohe-Duobaoshan-Sankuanggou metallogenic belt of northern part of the Da Hinggan Range. The ore-related Sankuanggou granodiorite yields a concordia LA-ICP-MS zircon U-Pb age of 175. 9 +/- 1. 6Ma in good consistently with U-238/Pb-206 weighted average age within error. This age indicates that there was an important Jurassic magmatic-hydrothermal Fe-Cu mineralization event in the Duobaoshan metallogenic district. The Sankuanggou granodiorite has a geochemical affinity of arc magmas; Na-rich (Na2O/K2O = 1.39 similar to 1. 59), rnetaluminous (ACNK = 0. 87 similar to 0. 91), enrichment in LREE ((La/Yb)(N) = 8.02 similar to 10. 45) and LILEs (U, Th and Pb) with minor negative Eu anomalies (delta Eu = 0. 82 similar to 0. 98), depletion in HFSE (Nb, Ta, Zr, Hf and Ti). Sr-Nd-Pb isotope systematics display that the Sankuanggou granodiorite also has a low initial I-st((Sr-87/Sr-86)(i) = 0. 7041 similar to 0. 7045), high initial Nd-143/Nd-144 value ((Nd-143/Nd-144)(i) = 0. 512556 similar to 0. 512576), positive epsilon(Nd)(t) (2. 8 similar to 3. 9), young depleted-mantle model ages (t(DM2) = 647 similar to 733Ma) and mantle-derived Pb isotopic characteristics. These geochemical characteristics indicate that the magma source of the Sankuanggou granodiorite may be mainly derived from deleted mantle source. The geochronology, geochemistry and isotope characteristics of the Sankuanggou granodiorite, combined with tectonic evolution of northeastern China, suggest that this deposit was formed in the magmatic arc setting, implying that its formation is probably related to the subduction of the paleo-Pacific Ocean during the Jurassic Period. |
