Deep Vertical Seismic Profiling at the Continental Deep Drilling Site Oberpflaz, Germany

9727654史密森在俄罗斯和德国对结晶岩进行深度科学钻探的一个最重要的结果可能是在整个深度范围(9至12公里)的深井中发现了含水流体。含水流体的存在是如此重要，因为即使是少量的含水流体，也会对矿物反应、熔融、岩石强度、物质转移、地震波衰减和矿床等地质过程产生巨大影响。流体产生的反射系数比单独从岩石-岩石界面上发现的反射系数更大，因此对地震反射率也有很大影响。该奖项支持与首席调查员的德国同事合作的项目的美国部分，该项目将在德国KTB井眼的深部(3-8.5公里)进行垂直地震剖面(VSP)，并在井中进行从地表到检波器的移动震源剖面(MSP)。ICDP(国际大陆科学钻探计划)已经批准了对该项目的资助。这项奖励将提供三分之一的数据获取成本。首席调查员将免费为项目贡献自己的时间，参与数据收集和数据分析。***

9727654 Smithson The single most important result from deep scientific drilling in crystalline rocks in Russia and Germany may be the discovery of hydrous fluids through the entire depth range (9 to 12 km) of deep boreholes. The presence of hydrous fluids is so important, because even in small amounts, they have a dramatic effect on geologic processes such as mineral reactions, melting, rock strength, material transfer, seismic wave attenuation and ore deposits. Fluids also strongly affect seismic reflectivity by creating larger reflection coefficients than can be found from rock-rock interfaces alone. This award supports the U.S. portion of a cooperative project with the Principal Investigator's German colleagues to conduct a vertical seismic profile (VSP) in the deep part (3-8.5 km) of the KTB borehole in Germany and a moving source profile (MSP) from the surface into geophones in the borehole. The ICDP (International Continental Scientific Drilling Program) has already approved funding for the project. This award will provide one-third of the data acquisition costs. The Principal Investigator will participate in the data acquisition and data analysis by contributing his time to the project at no charge. ***
