Fluid-Rock System Evolution During Folding: A Detachment Fold Example from the Mexican Sierra Madre Oriental

9972993 Fischer大多数构造环境中的岩石变形涉及广泛的岩石-流体相互作用，影响化学，矿物学和物理性质，如机械强度。 这个项目的目的是研究褶皱发育过程中涉及的流体-岩石相互作用，与断层岩中的流体-岩石相互作用相比，这方面很少受到关注。 该项目将采用几种技术来确定一个充分暴露的褶皱中的古水文地层单位，并将这些单位的时空演变与表现出特征变形模式的机械单位进行比较。 结果将被用来测试是否古水文地层单位相关的机械单位，以及流体是否岩石缓冲和流体流动划分的折叠过程的持续时间，重要的因素，在了解褶皱的作用，发挥区域造山流体系统。

9972993Fischer The deformation of rocks in most tectonic environments involves extensive rock-fluid interactions that affect chemistry, mineralogy, and physical properties such as mechanical strength. This project is aimed at examining fluid-rock interactions involved during fold development, a facet receiving little attention in comparison to fluid-rock interaction in fault rocks. The project will employ several techniques to define paleohydrostratigraphic units in a well exposed fold and compare the spacio-temporal evolution of these units with mechanical units exhibiting characteristic deformation patterns. Results will be used to test whether paleohydrostratigraphic units correlate with mechanical units, and whether fluids are rock-buffered and fluid flow is compartmentalized for the duration of the folding process, factors important in understanding the role folds play in regional orogenic fluid systems.
