南非林波波带的中部带主要经历三个变质演化阶段:3.22 Ga(M1),～2.66-2.61 Ga(M2)和2.02±0.02 Ga(M3)。侵位时间～2.61 Ga的布莱岩体(Bulai Pluton)的内部和边部均存在变泥质岩块体。前人通过变质锆石年代学研究显示,岩体边部变泥质岩... 详细信息

南非林波波带的中部带主要经历三个变质演化阶段:3.22 Ga(M1),～2.66-2.61 Ga(M2)和2.02±0.02 Ga(M3)。侵位时间～2.61 Ga的布莱岩体(Bulai Pluton)的内部和边部均存在变泥质岩块体。前人通过变质锆石年代学研究显示,岩体边部变泥质岩经历M2和M3两期麻粒岩相变质作用,

Understanding the thermodynamics and kinetics of complexation of actinide cations with various ligands are very important for spent fuel processing and nuclear waste *** a relativistic density functional approach,we have studied the kinetics of complexation of solvated neptunyl(V) ion[NpO(HO)] by acetate. The geometries,thermochemistry and reaction path of the complexation reactions are also *** find two local minima both with five-coordination:a neptunyl
