Non-Volatile Element and Volume Flux in Cleaved Rocks

在定向应力作用下发生的化学溶解作用可导致山系的主要构造变形。这一过程造成了岩石的化学元素枯竭，这些化学元素最容易被移除和替换。由于难以确定有多少物质被移除了，因此对岩石中因这一过程而改变的应变量的量化是难以捉摸的。本项目将通过比较变形区与相邻未变形区的总体化学含量来测量这种影响。这项技术的发展将为其他人提供对这类岩石进行常规分析的方法。

Major tectonic deformation of mountain systems can occur as the result of chemical dissolution that occurs under directed stress. This process creates zones of rock that become depleted in chemical elements that are most susceptible to removal and replacement. Quantification of the amount of strain in rocks changed by this process is elusive because it is difficult to determine how much material has been removed. This project will measure this effect by comparing the bulk chemical content of deformed zones with adjoining undeformed zones. Development of this technique will provide others with the methodology to allow routine analysis of such rocks.
