| 2 | Mineralization episode of porphyry copper deposits in the Jinshajiang-Red River mineralization belt: Re-Os dating显示文摘Re-Os isotopic dating for the molybdenites from the porphyry copper deposits of the Jinshajiang-Red River mineralization belt in Yunnan Province yields isochron ages of 33.9±1.1 Ma for the Machangqing deposit and 34.4±0.5 Ma for the Tongchang deposit. This result shows that both the Machangqing and the Tongchang porphyry Cu-Mo deposits from two different ore-fields formed simultaneously. This new data and the published Re-Os model ages of molybdenite (35.4 Ma, 35.9 Ma, 36.2 Ma) of the Yulong porphyry copper deposit in Tibet, which is located in the same Jinshajiang-Red River mineralization belt as the Machangqing deposit and the Tongchang deposit, suggest that these three Cenozoic porphyry copper deposits in the Jinshajiang-Red River mineralization belt were contemporary for their mineralization episode. That is to say, even their present locality is far away and nearly iso-distantly distributed, these three porphyry Cu(Mo) deposits belong to the same mineralization episode at the end of Eocene. | WANG Denghong, QU Wenjun, LI Zhiwei, YIN Hanlong4 & CHEN Yuchuan Institute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037, China National Center of Rock and Mineral Analysis, Chinese Academy of Geological Sciences, Beijing 100037, China Resource Assessment Center of Yunnan, Kunming 650011, China Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100101, China Chinese Academy of Geological Sciences, Beijing 100037, China | 2005 | Science China Earth Sciences2005，48，2： | 21 |
| 3 | Constraints on the Archean atmospheric oxygen and sulfur cycle from mass-independent sulfur records from Anshan-Benxi BIFs, Liaoning Province, China显示文摘The Archean atmospheric oxygen concentration and sulfur cycle was long debated. The banded iron formation (BIF) is a special type of the sedimentary formation, which has truly recorded the atmospheric and oceanic conditions at that time. In this study, the composition of multiple sulfur isotope (δ 34S/δ 33S/δ 32S) for sulfides bedded in the Archean (~2.7 Ga) BIFs, in Anshan-Benxi area of Liaoning Province has been measured. The value of △33S varies from -0.89‰ to +1.21‰, which shows very obvious mass-independent fractionation (MIF) signatures. These non-zero △33S values indicate that the Archean sulfur cycles are different from what it is today, which have been deeply influenced by gas phase photochemical reactions. Algoma-type BIFs which are closely related to the volcanic activity have negative △33S value, however, Superior-type BIFs which are far away from the volcanic center have positive △33S value. The δ 34S varies in a large range from -22.0‰ to +11.8‰, which indicates that the bacteria reduction activity has already existed at that time, and that the oceanic sulfate concentration has at least reached 1 mmol/L in local areas. Combined with the contemporaneous existence of the hematite, magnetite and the occurrence and preservation of the sulfur MIF, it can be inferred that the Archean atmospheric oxygen level must be at 10-2―10-3 of the present atmospheric level (PAL). | HOU KeJun1,2, LI YanHe1,2? & WAN DeFang1,2 1 Key Laboratory of Metallogeny and Mineral Resource Assessment, Institute of Mineral Resource, Chinese Academy of Geological Sciences (CAGS), Beijing 100037, China 2 Key Laboratory of Isotope Geology, CAGS, Beijing 100037, China | 2007 | Science China Earth Sciences2007，50，10： | 9 |
| 4 | Structure and Property of Bamboo Fiber显示文摘The chemical composition, fiber characteristics, crystalline structure, mechanical properties and thermal behavior of the five species of bamboo (Phyllostachys edulis cv.Pachyloe, Bambusa tootisk, Arundinaia amabilis, B.vulgaris cv. Vittata, and Dendrocalamus affinis) were studied with IR, X-ray, DSC and chemical analyses. The results indicated that the benzene-ethanol extractive content of bamboo was higher than that of wood, the content of lignin and the content of pentosan were 19.1% - 25.3% and 14.9% - 22.6%, respectively. Except for Ph. edulis cv. Pachyloe, the cellulose content in the other 4 species was over 50%. The average length of fiber of D. affinis was the longest (1.861 mm). The length/ width ratio of bamboo fiber was also higher than that of wood, and it was the highest for B.tootisk, which reached 142. The results of IR and X-ray confirmed that crystalline structure of bamboo fibers was cellulose, and A. amabilis had the highest crystallinity index. The differential thermal analysis (DSC) can be one of the methods to identify various fiber materials. After steam explosive pretreatment, cellulose content of D. affinis had increased from 50.5% to 69.2%, the crystallinity index had increased and the breaking tenacity of bamboo fibers was suitable for producing textile products, indicating that steam explosion is an useful pretreatment for bamboo fibers made into composite materials and textiles. | JIANG Jianxin1 YANG Zhongkai2 ZHU Liwei1 SHI Limin2 YAN Lijie1 1.

| 6 | Quantum dots enhance Cu^(2+)-induced hepatic L02 cells toxicity显示文摘As a new class of xenogenous nanoparticle,quantum dots (QDs) possess the potential to co-exist with Cu2+ in human liver.The combined toxicity is thus concerned.Considering QDs and Cu2+ are known ROS (reactive oxygen species) inducer,we investigated the combined oxidative stress and corresponding protective strategy using human hepatic L02 cells.The results demonstrated that the presence of a small amount of MPA-CdTe QDs (2 μg/mL) in a Cu2+ solution (2.5-20 μg/mL) resulted in a higher toxicity with up to 8-fold cell viability decrease,which was accompanied by cell morphology changes.The combined toxicity was then confirmed as ROS associated oxidative stress with up to 300% and 35% increase of the intracellular ROS level and glutathione S-transferase (GST) activity,respectively.N-acetylcysteine (NAC) can also provide almost complete protection against the induced toxicity.Therefore,the ROS associated oxidant injury might be responsible for the QDs-Cu2+/Cu2+ induced toxicity and could be balanced through cytoprotective antioxidant enzyme GST. | Yuxia Zhao,Kuangfei Lin,Wei Zhang,Lili Liu State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process,Shanghai 200237,China | 2010 | Journal of Environmental Sciences2010，22，12： | 5 |
