9613710霍维斯拟议的研究将集中在几个重要的问题，有关能源的矿物和岩石过程。 本文通过对流纹岩、安山岩和玄武岩玻璃水溶液的热力学测量，研究了含水岩浆系统的热力学。 在第二个项目中，将研究简单碱-硅玻璃的混合特性。 在第三个项目中，溶解热将被用来从能量上表征减压非晶材料的残余结构。 其他项目涉及与相干出溶矿物中的应变以及与长石和其他矿物系统中的高度精确热力学混合相关的热释光。 用于这些研究的主要技术包括氢氟酸溶液量热法、室温/压力和高压X射线粉末衍射、核磁共振和其他光谱法。

9613710 Hovis The proposed research will focus on several important questions concerning the energies of mineral and rock processes. The energetics of water-bearing magmatic systems will be investigated by measuring the enthalpies of solution of hydrous rhyolite, andesite and basalt glasses. In a second project, the enthalpies of mixing for simple alkali-silica glasses will be investigate. In a third project, heats of solution will be used to energetically characterize the remnant structures of decompressed amorphous materials. Other projects relate to enthalpies associated with strain in coherently exsolved minerals and with highly precise thermodynamic mixing in feldspars and other mineral systems. The principal techniques to be utilized for these studies include hydrofluoric acid solution calorimetry, room temperature/pressure and high-pressure x-ray powder diffraction, and nuclear magnetic resonance plus other spectroscopies.
