1安徽沿江地区燕山期含铜岩体稀土、微量地球化学特征显示文摘安徽沿江地区位于长江中下游岩浆成矿带中段,其中众多矿床的形成与燕山期岩浆密切相关。对安徽沿江地区(铜陵、安庆和庐纵)燕山期中酸性含铜岩体地球化学研究表明:含铜岩体稀土特征总体表现为右倾型,LREE富集,HREE亏损但表现为平缓的曲线,无明显的Eu异常,∑REE含量变化范围在85.84×10^-6~446.26×10^-6,(La/Yb)N值为7.87至63.8,具有高Th,Sr;低Cr,Ni;La/Nb(平均值为3.4),Nb/U(平均值为5.24)和Nb/Pb(平均值为1.47)等特征,结合同位素特征,为壳幔混熔的物源区。研究还表明,本区燕山期含铜岩体可能来自于底侵的慢源碱性玄武岩浆同化混染古老地壳物质同时结晶分异的产物。其中岩体中的铜能否参与成矿关键取决于是否发生热液蚀变交代作用。谢建成 杨晓勇 Insung Lee 2008矿物岩石2008,28,1:10
2Mineralization,Geochemistry and Zircon U-Pb Ages of the Paodaoling Porphyry Gold Deposit in the Guichi Region,Lower Yangtze Metallogenic Belt,Eastern China显示文摘The newly discovered Paodaoling porphyry Au deposit from the Guichi region, Lower Yangtze River Metallogenic Belt(LYRB), contains >35 tons of Au at an average grade of ~1.7 g/t. It is a porphyry ‘Au-only' deposit, as revealed by current exploration in the depths, mostly above-400 m, which is quite uncommon among coeval porphyry mineralization along the LYRB. Additionally, there are also Cu-Au bearing porphyries and barren alkaline granitoids in the Paodaoling district. Zircon LA-ICP-MS U-Pb dating of the Cu-Au-bearing porphyries yield an age of 141–140 Ma, falling within the main magmatic stage of the LYRB, whereas the barren granites give an age of 125–120 Ma, coeval with the regional Atype granites. The Cu-Au-bearing porphyries are LILE-, LREE-enriched and HFSE-depleted, typical of arc magmatic affinities. The barren granites are HFSE-enriched, with lower LREE/HREE ratios and pronounced negative Eu anomalies. The Cu-Au-bearing porphyries in the Paodaoling district have high oxygen fugacities and high water content. Pyrite sulfur isotopes of the Paodaoling gold deposit indicate a magmatic-sedimentary mixed source for the ore-forming fluids. Based on the alteration and poly-metal zonation of the deepest exploration drill hole from the Paodaoling Au deposit, we propose that Cu ore bodies could lie at depth beneath the current Au ore bodies. The magmatism and associated Cu-Au mineralization of the Paodaoling district are likely to have formed in a subduction setting, during slab rollback of the paleo-Pacific plate.DUAN Liu'an YANG Xiaoyong DENG Jianghong WANG Fangyue LEE Insung 2018Acta Geologica Sinica(English Edition)2018,92,2:6
3Piaoac Granites Related W-Sn Mineralization, Northern Vietnam: Evidences from Geochemistry, Zircon Geochronology and Hf Isotopes显示文摘Piaoac granites exposed in the Cao Bang region, northern Vietnam, are S-type granite, which are associated with W-Sn-Mo-Be-F mineralization. Zircon U-Pb ages, major and trace elements, mineral chemical and Hf isotopic compositions of the W-Sn-bearing granites from the Piaoac District have been investigated in detail. LA-ICP-MS U-Pb dating of zircon grains from these granites yielded ages of 82.5±2.3 and 82±1.8 Ma, representing an episode of Late Cretaceous magmatic event. These granites are characterized by high peraluminous and have typical S-type geochemical signatures with high SiO_2(72.37 wt.%–73.07 wt.%), high A/CNK values(1.61–1.65) and Al_2O_3(14.4 wt.%–15 wt.%). They are enriched in Rb, U, K, Th, Ta and Pb and display pronounced negative Ba, Sr, Nb, Ti and Eu(Eu/Eu*=0.19–0.24) anomalies. The high degree of fractional crystallization is characterized by low Rb, Sr, Ba and Eu concentrations with high ratios of La/Sm and Eu/Eu*. Zircon grains show εHf(t) values from-9.69 to-0.9 and the corresponding TDM2 range from 1.2 to 1.7 Ga, indicating that these granites could be derived from the Proterozoic basement rocks with minor input from mantle-derived magmas. The calculation of Fe^(3+) and Fe^(2+) of biotites indicates a low oxygen fugacity condition(log fO_2 ranging from 10-17 to 10-18 bars, below MH), which is favorable for the W-Sn mineralization. Tungsten and tin have been enriched in granitic magmas through fractionation, and low oxygen fugacity conditions have promoted the accumulation and transportation of W-Sn in the hydrothermal fluids, leading to deposition of mineral phases. The geochemical data suggest that Piaoac granites formed in an extensional setting related with the Late Cretaceous magmatism occurring large-scale lithospheric extensional in South China Block.Tuan Anh Nguyen Xiaoyong Yang Hien Vu Thi Lei Liu Insung Lee 2019Journal of Earth Science2019,30,1:2

9Tree-Based Index Overlay in Hybrid Peer-to-Peer Systems显示文摘Hybrid Peer-to-Peer(P2P) systems that construct overlay networks structured among superpeers have great potential in that they can give the benefits such as scalability,search speed and network traffic,taking advantages of superpeer-based and the structured P2P systems.In this article,we enhance keyword search in hybrid P2P systems by constructing a tree-based index overlay among directory nodes that maintain indices,according to the load and popularity of a keyword.The mathematical analysis shows that the keyword search based on semi-structured P2P overlay can improve the search performance,reducing the message traffic and maintenance costs.InSung Kang SungJin Choi Member, IEEE SoonYoung Jung SangKeun Lee 2010Journal of Computer Science & Technology2010,25,2:1
