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.

在这项建议中，PIS及其俄克拉荷马大学的合作者建议通过实验设置进行，测试和进行实验，以通过实验材料中的裂缝来测量液体的流动。裂缝将包括简单的单个裂纹和相互连接的3D裂纹网络。固体基质将由干燥的环氧树脂，二氧化硅玻璃组成，液体将被去离子并加入染料。一些实验将检查Caso4和其他物质对通过裂纹和裂纹网络流动的降水和溶解的影响。流速将在专门设备的实验室中使用相机技术测量。然后，这些简单实验的结果将用于尝试更好地了解海底热液系统中发生的过程。
