| 3 | An Isotopic(Sr,Nd and Pb) Tracer Study on the Xiaoxinancha Gold-rich Copper Deposit in Yanbian,China:Implication for the Geodynamic Model of Diagenesis and Metallogenesis显示文摘同位素的研究全身地在吉林省在花岗石的建筑群, diorite-porphyrite,矿石和 103 妈 Xiaoxinancha 充满黄金的铜沉积物的矿石矿物质上被执行决定成岩作用和 metallogenesis 的 geodynamic 模型。结果证明花岗石的建筑群的同位素的作文在 0.704250.70505 的范围为的起始的 Nd 和 Sr (87Sr/86Sr ) 我, 0.512430.51264 为 INd,并且 1.31 ~ + 2.64 为 Nd (t) ;diorite-porphyrite 的那些在从 0.704380.70448 的范围为(87Sr/86Sr ) 我, 0.512590.51261 为 INd,和 +1.56 ~ + 2.09 为 Nd (t) 。为矿石和硫化物,(87Sr/86Sr ) 我, INd,和 Nd (t) 价值在从 0.704400.70805 的范围, 0.512590.51279 并且 +1.72 到 +5.56 分别地。花岗石的建筑群的 Pb 同位素的比率为 208Pb/204pb 为 207Pb/204Pb 为 206Pb/204Pb 从 18.299218.6636 ,从 15.534315.5660 ,并且从 38.164038.5657 因为分别地, diorite-porphyrite , 206Pb/204Pb 的同位素的比率, 207Pb/204Pb 和 208Pb/204b 是 18.3919 , 15.5794 和 38.3566 而那些为 206Pb/204Pb 从 18.227518.3770 矿石和矿石硫化物变化,从 15.555515.5934 为 207Pb/204Pb 并且从 38.131838.3131 为 208Pb/204Pb 。结果显示矿化作用被相关到花岗石的建筑群和 diorite-porphyrite 的形成和进化。在岩石学的特征,元素的地球化学和年表与报导数据结合,结论能被得出成岩作用的 geodynamic 设置和这的 metallogenesis 扔,这在早白垩纪期间与 Izanagi 海洋的板的 subduction 一致。diorite-porphyrite 被充实的披风的部分融化触发的 adakitic 岩浆的炮兵阵地形成,它从 subducting 由脱水液体从衍生物大陆人 lithospheric 披风 metasomatized 发源海洋的外壳。花岗石的建筑群被在 adakitic 岩浆和 high-K 之间的混合的部分结晶化生产计算碱的酸的岩浆,它被更低的外壳的 remelting 在 adakitic 岩浆的 intraplate upwelling 期间产生。忍受矿石的液体水库集合在混合岩浆房间的进化的一个迟了的阶段。 | MEN Lanjing SUN Jinggui ZHANG Zengjie LI Yixin XING Shuwen CUI Peilong | 2011 | Acta Geologica Sinica(English Edition)2011，85，1： | 7 |
| 5 | The Relationship Between Physical Activity and All-Cause Mortality Among Older Adults--China, 1998–2018显示文摘Summary What is already known about this topic?Previous research indicates that non-occupational physical activity can reduce mortality risk.Nevertheless,the relationship between occupational physical activity and health improvements has not been consistently established.What is added by this report?The study found that regular exercise and leisure activities reduced the risk of all-cause mortality.However,the combination of exercise and leisure activities demonstrated more substantial benefits.Additionally,no meaningful association was identified between physical work and mortality risk within the older population. | Lanjing Xu Jun Wang Yang Li Xinwei Li Chen Chen Zinan Xu Min Zhang Yidan Qiu Zhuchun Zhong Zheng Zhang Fangyu Li Yufei Luo Yuebin Lyu Guangdi Chen Xiaoming Shi | 2023 | China CDC weekly2023，5，39： | 0 |
