Constraints on the Mechanics of Ocean Crustal Faults

多年来，通过研究从裸露断层收集的样本，人们对陆地上的断层和断层过程有了很多了解。断层岩石吗?。织物元素（如颗粒取向和剪切感）、变形历史和强度和渗透性等特性的测量是许多实验室几十年来研究的重点，但由于它们难以获得，因此没有对断层岩进行此类研究。利用各种来源的样本，包括潜水取样、钻探和蛇绿岩，这项研究将是第一个来自海底的断层岩。作为第一次进入一个新的研究领域的冒险，它将面临许多困难，但同样几乎肯定会产生新的见解。这项工作的更广泛的影响是它对基础知识的贡献，对年轻研究者的支持，以及对研究生的支持。

Over the years much has been learned about faulting and fault processes on land through the study of samples collects from exposed fault, ?fault rocks?. Measurements of fabric elements (such as grain orientation and sense of shear), deformation histories and properties such as strength and permeability have been the focus of research in many laboratories for decades, but owing to their inaccessibility, no such studies of fault rocks have been carried out. Using samples from a variety of sources including submersible sampling, drilling and ophiolites where oceanic rocks are exposed on land, this study will be the first of fault rocks from the seafloor. As a first venture into a new area of research it will face a number of difficulties, but will likewise almost certainly yield new insights. The broader impacts of this work are its contribution to fundamental knowledge, support for a young investigator, and support for a graduate student.
