Fracture-Fluid Evolution in the Deep Portions of Submarine Hydrothermal Systems

该项目将对来自海洋钻探项目735B岩心的深成矿样品以及从亚特兰蒂斯II断裂带中回收的一系列深成矿和辉绿岩样品进行空间、热和成分分析。这些延性变形和热液蚀变岩石中裂缝结合流体的显微温度测量结果将用于建立与缓慢扩张环境相关的海底热液系统高温根区裂缝流体演化模型。

This project will conduct spatial, thermal, and compositional analyses of fluid inclusions in plutonic samples from Ocean Drilling Project core 735B and a suite of metaplutonic and diabase samples recovered from the Atlantis II fracture zone. Microthermometric results of fracture-bound fluids in these ductily-deformed and hydrothermally altered rocks will be used to develop a model for fracture-fluid evolution in the high- temperature root zones of submarine hydrothermal systems associated with slow spreading environments.
