1Mechanism of inversion metallogeny of quartz vein type gold deposits in the Xiaoqinling region显示文摘There are a lot of important gold_bearing quartz veins in the Xiaoqinling metamorphic core complex. The quartz veins are strictly controlled by shear zones. Stress analysis indicates that the metallizing process of the Xiaoqinling gold deposits of quartz vein type can be divided into two stages. At the first stage, the shear zones were formed in an extensional environment, and the temperature was higher and the buried depth was greater; at the second stage, the brittle thrusts were superimposed in ductile shear zones after the tectonic stress field turned from the extension to compression. The ore_bearing fluids were concentrated in these weak positions, and the gold deposits of quartz vein type were developed.Liangwei Xue Quanzeng Shi Xiangdong Yu Yadong Zheng Jinjiang Zhang 1998Chinese Science Bulletin1998,43,10:2

3Investigation of the Effect of Metallic Lewis Acid on the Nitrolysis of [3,7-Diacetyl-1,3,5,7-tetraazabicyclo(3.3.1)- nonane] and Hexamine显示文摘DAPT 的 nitrolysis 上的金属性的离子的效果[3,7-diacetyl-1,3,5,7-tetraazabicyclo (3.3.1 ) nonane ] 并且哈(hexamine ) 被试验性、理论的途径调查。组合试剂, M (没有 ? 3 ) n/Ac2/NH4NO3 (M=Mg2+ , Cu2+ , Pb2+ , Bi3+ , Fe3+ 和 Zr4+) ,被发现在 DAPT 的 nitrolysis 的实验有效。在 DAPT 的 nitrolysis 期间中间的一把钥匙被 1H NMR 检测。中介的形成机制被建议并且分析。DAPT 的 nitrolysis 的一些差异的结果并且哈由不同金属性的硝酸盐催化基于难软、酸硷的原则被解释并且稳定了离子建筑群的精力。从后者观点,有高 polarizable ligands 的一些阳离子,例如, OSO2CF3 ? ,(CF3SO2 ) 2N ? ,并且(C4F9SO2 ) 2N ? ,能增加收益。二最新设计的催化剂, Cu [(CF3SO2 ) 2N ] 2 并且 Cu [(C4F9SO2 ) 2N ] 2,被测试高度有效。Shi Liangwei Yu Menglong Zhang Yazhu Qin Guangming Lv Jian Zhao Gang 2011Chinese Journal of Chemistry2011,29,2:0
