The proposed research will involve theoretical studies of a variety of different kinds of reaction between fluid and rock. It will include: 1. Gravitational instabilities ranging from situations of rapid melt segregation to cases in which segregation is slow or negligible 2. Chemical exchange balanced by diffusion in the fluid phase: An application of this regime is the exchange of Sr between carbonates and their contained porewaters. 3 Exchange limited by diffusion in the solid phase. The thermal history in the vicinity of the conduit at Inyo Domes is sufficiently well known that it should be possible to determine the diffusion parameters of feldspars in their natural setting, and compare it to laboratory diffusion data to test the key assumption of thermochronometry that laboratory data can indeed be extrapolated to give geologically relevant diffusion rates.

这项拟议的研究将涉及流体和岩石之间各种不同类型的反应的理论研究。它将包括：1.重力不稳定性，从熔体快速分离到分离缓慢或可以忽略的情况；2.通过在流体中的扩散来平衡化学交换阶段：这一制度的一个应用是碳酸盐及其所含孔隙水之间的锶交换。3交换受固相扩散的限制。Inyo穹顶管道附近的热历史是众所周知的，因此应该有可能确定长石在其自然环境中的扩散参数，并将其与实验室扩散数据进行比较，以检验热计时学的关键假设，即实验室数据确实可以外推，以得出地质上相关的扩散速率。
