Collaborative Research: Seismic Investigation of the Rainbow Hydrothermal Field and its Tectono/magmatic Setting, Mid-Atlantic Ridge 36 Degrees 14'N

在与板块构造有关的最令人兴奋和意想不到的发现中，发现了地球上的热液喷口？的洋中脊系统。这些深温泉不仅支持各种异国情调的生命形式，它们现在被认为是从地球提取热量的主要手段？海洋是海底和海洋之间化学交换的主要途径。但是，这些系统如何获得热量，以及它们与构造环境的关系仍然知之甚少。该项目将采用三维和二维高分辨率地震层析成像、二维多通道反射和微地震建模相结合的方法，确定大西洋中脊彩虹热液田岩浆活动、断层活动、基底岩性（岩石类型）和热液循环之间的关系。这一综合办法旨在检验与热液活动及其与地质环境的关系有关的若干假设。更广泛的影响包括对大洋中脊系统的国际研究作出重大贡献，支持两个博士学位。毕业论文项目和本科实习生的经验。

Among the most exciting and unexpected findings related to plate tectonics was the discovery of the hydrothermal vents that populate the earth?s mid-ocean ridge system. Not only do these deep hot springs support a variety of exotic life forms, they are now known to be a primary means by which heat is extracted from the earth?s interior and to be a primary means of chemical exchange between the seafloor and the oceans. But just how heat is supplied to these systems, and how they relate to the tectonic environment remains poorly understood. This project will employ a combination of 3D and 2D high resolution seismic tomography, 2D multichannel reflection and micro-earthquake modeling define the relationship between magmatism, faulting, substrate lithology (rock types) and hydrothermal circulation at the Rainbow Hydrothermal Field on the Mid Atlantic Ridge. This integrated approach is designed to test several hypotheses related to hydrothermal activity and its relationship to the geological environment. Broader impacts include a substantial contribution to international studies of the mid-ocean ridge system, support for two Ph.D. thesis projects and experience for undergraduate interns.
