In this proposal the PIs and their collaborator at the University of Oklahoma propose to build, test, and conduct experiments with an experimental setup to measure flow of liquid through cracks in experimental materials. The cracks will consist of simple single cracks and also interconnected 3D crack networks. The solid matrix will consist of dried epoxy resin, silica glass and the fluid will be deionized and degassed distilled water with dye added. Some experiments will examine the effects of precipitation and dissolution of CaSO4 and other substances on flow through cracks and crack networks. The flow rates will be measured using camera techniques in a specially equipped lab. The results of these simple experiments will then be used to try to better understand the processes occurring in sea floor hydrothermal systems.

在这个提案中，pi和他们在俄克拉何马大学的合作者提议用一个实验装置来建立、测试和进行实验，以测量液体通过实验材料裂缝的流动。裂缝将由简单的单个裂缝和相互连接的三维裂缝网络组成。固体基质将由干燥的环氧树脂和硅玻璃组成，液体将被去离子和除气，并添加染料的蒸馏水。一些实验将研究CaSO4和其他物质的沉淀和溶解对裂缝和裂缝网络流动的影响。流速将在一个特殊装备的实验室里用摄像技术测量。这些简单实验的结果将被用来更好地理解海底热液系统中发生的过程。
