Muddy Waters: Deep-seated fluid flow processes, seismic faulting and mud volcanism in a mature collision zone

岩土、地球化学和孔隙压力数据将在德国？领导了东地中海希腊俯冲带的现场调查，以支持IODP提案555-Full 3。这项调查和IODP提案的目的是了解？中间循环?俯冲工厂，在脚趾后面几十到几百公里。地中海海岭是一个成熟的碰撞带，它提供了一个简单的钻井通道，可以在一个增生棱镜及其支撑中进入深部流体流动过程。该项目将重点关注断层驱动的前缘和中间环流体释放，并将通过热液岩土实验和孔隙流体地球化学分析进行现场量化和校准。将部署CAT流量计，就地测量孔隙压力，并在断层露头处收集重力岩心进行地球化学分析。岩土和地球化学数据将被纳入一个增生杂岩与其腹地之间流体流动的数值模型。更广泛的影响：这项研究将加深我们对增生复合体支撑区断裂带的地球动力学和物理化学过程的理解。该项目的数据和信息将支持高排名的IODP提案，并将加强IODP科学家之间的国际合作。PI是一位早期的职业科学家，他将与斯克里普斯海洋学研究所伯奇水族馆的教育工作者一起工作，以便将该项目产生的信息传播给广泛的非学术受众。

Geotechnical, geochemical, and pore pressure data will be collected during a German?led site survey of the Hellenic Subduction Zone in the eastern Mediterranean in support of IODP Proposal 555-Full 3. The aim of this survey and the IODP proposal is to understand the ?intermediate loops? of the subduction factory, which are several tens to hundreds of kilometers behind the toe. The Mediterranean Ridge is a mature zone of collision and provides easy drilling access to deep seated fluid flow processes in an accretionary prism and its buttress. This project will focus on fault-driven fluid release from the frontal and intermediate loop, which will be quantified in situ and calibrated by hydrothermal geotechnical experiments and geochemical analyses of the pore fluids. CAT flow meters will be deployed, in situ pore pressures measured, and gravity cores collected at the outcrops of the faults for geochemical analyses. The geotechnical and geochemical data will be incorporated into a numerical model of fluid flow between the accretionary complex and its hinterland. Broader impacts: The research will deepen our understanding of the geodynamic and physico-chemical processes along fault zones in the buttress region of an accretionary complex. The data and information from this project will support a highly ranked IODP Proposal and will strengthen international collaborations between IODP scientists. The PI is an early career scientist who will work with educators at the Birch Aquarium at the Scripps Institution of Oceanography in order to disseminate the information generated from this project to a broad non-academic audience.
