RPG: An Investigation of Silicon Diffusion Minerals

9315051切尔尼亚克这项研究计划拨款要求支持研究硅在矿物中的自我扩散，最初的重点是长石的研究。将使用30Si示踪剂和卢瑟福背散射光谱仪(RBS)直接测量硅扩散，以深度剖析示踪剂分布。实验结果可用于更好地理解Al-Si有序、Caal-Nasi互扩散和涉及地球化学元素和地质年代学意义的元素的化学扩散。

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.
