Flow Laws for Quartzo-Feldspathic Aggregates

其目的是通过实验确定能够可靠地外推到地壳条件下的石英和长石的单相和多相集合体的位错和扩散蠕变的流动规律。这项研究的一个关键因素是使用熔盐样品组件，它提供了几乎气体设备的应力敏感性，以及诱导石英和长石中位错蠕变所需的高压能力。这项研究的结果将为解释地壳变形提供更好的力学数据，并对适用于其他硅酸盐的扩散和位错蠕变有基本的理解。

The objectives are to experimentally determine flow laws for dislocation and diffusion creep of mono-and polyphase aggregates of quartz and feldspar which can be reliably extrapolated to crustal conditions. A key element of the study will be use of molten salt sample assemblies, which provide nearly the stress sensitivity of gas apparatus together with the high pressure capability required to induce dislocation creep in quartz and feldspar. The results of this study should provide greatly improved mechanical data for interpreting crustal deformation, plus fundamental understanding of diffusion and dislocation creep applicable to other silicates.
