9912062Franseen Ground-penetrating radar (GPR) is a relatively untested method for outcrop studies that has the potential to: 1) greatly aid in our understanding of the near-surface stratigraphic record, 2) allow direct imaging of three-dimensional geometries and heterogeneities of sedimentary bodies, and 3) provide the ability to predict some petrophysical properties needed for understanding rock properties, stratal architecture, and modeling fluid flow in strata that are important analogs to subsurface aquifers and petroleum reservoirs. This project combines a team of sedimentologists/stratigraphers, geophysicists, hydrogeologists and petrophysicists, and utilizes new scientific approaches to investigate the controls on GPR attributes and to demonstrate the potential of GPR to the stratigraphic record for outcrop studies. The field site for the project is located in a quarry where limestone and siliciclastic strata of interest for this project will be actively quarried in conjunction with the design of the project. The approaches to be used in this study include detailed outcrop and core studies of stratigraphic and geologic rock properties, rigorous geophysical testing of GPR, including the utilization of new methods recently pioneered by members of the team, collection of petrophysical data on pore geometry and porosity/permeability influences on GPR reflection characteristics, synthetic GPR modeling, and fluid-flow modeling. The methods and results from this proposed study and future extensions will help advance GPR into the mainstream of geophysical methods utilized in outcrop studies for stratigraphic, sedimentologic, and fluid-flow applications.

9912062Franseen探地雷达（GPR）是一种相对未经测试的露头研究方法，有可能：1)极大地帮助我们理解近地表地层记录，2)允许对沉积体的三维几何形状和非均质性进行直接成像，3)提供预测一些岩石物理性质所需的能力，以理解岩石性质、地层结构和模拟地层中的流体流动，地层是地下含水层和油藏的重要类似物。该项目结合了沉积学家/地层学家、地球物理学家、水文地质学家和岩石物理学家的团队，利用新的科学方法来研究探地雷达属性的控制，并展示了探地雷达对露头研究的地层记录的潜力。该项目的现场位于一个采石场，该采石场将与项目设计一起积极开采该项目感兴趣的石灰石和硅塑性地层。本研究中使用的方法包括详细的露头和岩心地层和地质岩石性质研究，严格的探地雷达地球物理测试，包括利用团队成员最近首创的新方法，收集孔隙几何形状和孔隙度/渗透率对探地雷达反射特征的影响的岩石物理数据，合成探地雷达建模和流体流动建模。本研究的方法和结果以及未来的扩展将有助于推动探地雷达成为地层学，沉积学和流体流动应用的露头研究中使用的主流地球物理方法。
