The principal investigator, in collaboration with Dr. Melinda Dyar of the University of Oregon, will study the crystal chemistry of coexisting biotite, muscovite, and chlorite from several different representative rock provenances. Electron microprobe, Mossbauer, and other analytical techniques will be utilized. The work will lead to a better understanding of the location of vacancies in the structures of these minerals. It also will lead to a better understanding of the chemical substitutions that occur in the minerals and of the controls on the partitioning of ferric iron and hydrogen among crystallographic sites in the minerals, as well as between mineral pairs. These data will be of importance to geologists who use these minerals to estimate the geologic conditions of formation of rocks in which the minerals occur.

首席研究员与梅林达·戴尔博士合作 俄勒冈州大学的教授，将研究 共存的黑云母，白云母，和来自几个不同的 代表性的岩石来源。电子探针，穆斯堡尔， 并将使用其他分析技术。这项工作将 有助于更好地了解 这些矿物的结构。这也将导致一个更好的 了解发生在化学物质中的化学取代， 矿物和控制分配的三价铁和 氢在矿物的晶体位置，以及 矿物质对之间。这些数据将对 地质学家用这些矿物来估计 形成矿物的岩石的形成条件。
