9301730 Gieskes The objectives of this research project (a renewal) include work on (1) design, construction, and testing of an ocean borehole-fluid water sampler that could be deployed using wireline borehole reentry techniques, (2) sampling of selected ocean boreholes using opportunities provided by French NADIA/NAUTILE reentry facility activities near selected Deep Sea Drilling Project/Ocean Drilling Program boreholes in 1993-1994, (3) water sampling at holes of opportunity, to be collected from the JOIDES Resolution during ocean drilling legs during 1993-1994, and (4) laboratory experimentation and modelling of water-rock geochemistry at varying temperatures and pressures. Sampling and chemical analysis of ocean borehole fluids will provide insights to the nature of seawater - borehole wall rock chemical reactions, and should help answer fundamental questions about the role that formation fluids may play in seawater-borehole interactions. Together with modelling efforts, these observations will also ultimately be of importance in understanding hydrothermal reactions in high- temperature ocean boreholes. ***

9301730 Gieskes本研究项目的目标（更新）包括以下工作：（1）设计、建造和测试可使用电缆钻孔再入技术部署的海洋钻孔流体水取样器，（2）利用法国NADIA/NAUTILE重返大气层设施在选定的深海钻探项目附近开展活动的机会，对选定的海洋钻孔进行取样; 1993年至1994年期间，海洋钻探方案钻孔的水取样，（3）在机会孔的水取样，将在1993年至1994年期间的海洋钻探期间从JOIDES Resolution收集，（4）在不同温度和压力下的水-岩石地球化学实验室实验和模型。 海洋钻孔流体的采样和化学分析将提供对海水-钻孔围岩化学反应性质的深入了解，并应有助于回答有关地层流体在海水-钻孔相互作用中可能发挥的作用的基本问题。 这些观测与建模工作一起，最终也将对了解高温海洋钻孔中的热液反应具有重要意义。 ***
