The principal investigator will study the degree to which ductile strain increases bulk diffusion rates in olivine. Experiments will be performed in a Griggs apparatus, and the resulting samples will be examined via electron microscopy and with the electron microprobe. The results will be important to structural geologists, geochemists, and metamorphic petrologists who deal with kinetics and equilibrium in deformed rocks.

首席研究员将研究延性应变在多大程度上增加了橄榄石中的体扩散速率。实验将在格里格斯仪器中进行，所得样品将通过电子显微镜和电子显微探针进行检查。这些结果对于研究变形岩石动力学和平衡的构造地质学家、地球化学家和变质岩石学家具有重要意义。
