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.

这项研究计划拨款要求支持研究硅在矿物中的自扩散，最初集中在长石的研究上。硅扩散将使用30Si示踪剂和卢瑟福后向散射光谱法（RBS）直接测量示踪剂分布的深度剖面。实验结果可用于更好地理解Al-Si有序、cal - al - nasi相互扩散以及涉及地球化学和地质年代学元素的化学扩散。
