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.

[9613710]霍维斯：拟议的研究将集中在有关矿物和岩石过程能量的几个重要问题上。通过测定含水流纹岩、安山岩和玄武岩玻璃的溶解热焓，研究含水岩浆体系的能量学。在第二个项目中，将研究简单碱-硅玻璃的混合焓。在第三个项目中，溶液热将用于能量表征减压非晶材料的残余结构。其他项目涉及到与连续溶解矿物的应变有关的焓，以及长石和其他矿物系统的高精度热力学混合。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学。
