Diffusive isothermal partitioning in a layered medium with geologic applications
Abstract
The diffusive isothermal partitioning of solute in a layered two-phase material has been analyzed to help elucidate the phenomenon of solute partitioning in multiphase lunar and terrestrial materials and to estimate the cooling history of samples. After reviewing the physical chemistry of partitioning and the case of a infinite one-dimensional diffusion couple, we solve in analytic form the case of a finite onedimensional couple. The solution can be used to estimate cooling histories or to interpret laboratory experiments on partitioning. A sample calculation is included.
