The principal investigator will study three important questions in mineral physics: Does crystal growth rate change abruptly at a critical size as elastic strain energy increases? What factors most affect grain boundary diffusion rates in monomineralic aggregates? What energies are associated with dislocations in minerals, and to what extent do these affect mineral transformations? All of these studies are important if we are to have fundamental understanding of mineral behavior.

首席研究员将研究三个重要问题， 矿物物理学：晶体生长速率是否会突然改变， 临界尺寸随弹性应变能的增加而增加？哪些因素最 影响单矿物聚集体中的晶界扩散速率？ 什么能量与矿物中的位错有关， 这些因素对矿物转化的影响有多大？所有这些 如果我们想从根本上了解 矿物的行为。
