9315051 Cherniak This research planning grant requests support to investigate silicon self-diffusion in minerals, with initial concentration on the study of feldspar. Silicon diffusion will be measured directly with the use of a 30Si tracer and Rutherford Backscattering Spectrometry (RBS) for depth profiling of the tracer distribution. Results from the experiments can be applied in better understanding of Al-Si ordering, CaAl-NaSi interdiffusion, and chemical diffusion involving elements of geochemical and geochronologic interest.

9315051 Cherniak这项研究计划赠款请求支持调查矿物质硅自扩散，最初专注于Feldspar的研究。 硅扩散将通过使用30SI示踪剂和卢瑟福反向散射光谱法（RB）直接测量，以进行示踪剂分布的深度分析。 实验的结果可以应用于更好地理解AL-SI订购，CAAL-NASI互化以及涉及地球化学和地球学兴趣元素的化学扩散。
