Modulated Layer Silicates

采用岩石学和矿物学相结合的方法对富锰贫铝调制层状硅酸盐矿物进行研究，以评价其构造稳定性。这项研究将确定理想的四面体和八面体之间的不匹配是否是产生调制层硅酸盐结构的必要条件。此外，还将对澳大利亚格伦费尔矿床进行研究，以确定顺序变质作用对矿物相的影响。这项工作将与堪培拉澳大利亚国立大学的R.A.埃格尔顿博士合作完成。使用超高分辨率的透射电子显微镜和X射线衍射技术。

Manganese-rich, aluminum-poor modulated layer silicate minerals are to be studied by using an integrated petrologic and mineralogic approach to assess structural stability. This study will determine if the misfit between the ideal sheets of tetrahedra and octahedra is a requirement to produce a modulated layer silicate structure. In addition, the Grenfell deposit, Australia, will be studied to determine the effect of sequential metamorphism on the mineral phases. The work will be done in collaboration with Dr. R.A. Eggleton of the Australian National University, the Canberra. Using ultra-high resolution transmission electron microscopy (TEM) and X-ray diffraction techniques.
