The objectives of this research on pelitic metamorphic rocks at SMU are: (1) to work out stability relations of minerals, and (2) to determine metamorphic conditions and history of a number of pelitic metamorphic terrances. In addition to finishing the Picuris and ferric-ferrous study on staurolite during 1989, Holdaway will: (1) complete the study of low-pressure metamorphism in Maine; (2) complete the determination of Fe- cordierite stability; and (3) undertake a study of possible staurolite nonideality and retrieve a self-consistent set of thermodynamic data-set that promises to provide useful constraints on pressure, temperature, and fluid composition in petitic metamorphic rocks. This will add to our understanding of the conditions under which clays (shales, when lithified) are buried, heated, and become schists.

本研究的目的是对泥质变质岩进行研究， SMU的主要功能是：（1）求出矿物的稳定性关系; 以确定变质条件和历史的一些 泥质变质碎屑岩 除了完成 1989年十字石中的Picuris和铁-亚铁研究， 保持将：（1）完成低压研究 （2）完成了对铁- 堇青石的稳定性;和（3）进行可能的研究 十字石非理想性，并检索一组自洽的 热力学数据集，承诺提供有用的 压力、温度和流体成分的约束， 小变质岩 这将增加我们对 粘土（页岩，当锂化时） 埋藏加热变成了片岩
