9912062 Franseen探地雷达（GPR）是一种相对未经测试的露头研究方法，具有以下潜力：1）极大地帮助我们理解近地表地层记录，2）允许直接成像沉积体的三维几何形状和不均匀性，以及3）提供预测理解岩石性质，地层结构，以及模拟地层中的流体流动，所述地层是地下含水层和石油储层的重要类似物。该项目结合了一个由沉积学家/地层学家、地质学家、水文地质学家和岩石物理学家组成的团队，并利用新的科学方法来研究对GPR属性的控制，并证明GPR对露头研究的地层记录的潜力。 本项目的现场位于一个采石场，在该采石场，本项目的石灰石和硅质岩地层将结合项目设计积极开采。在这项研究中使用的方法，包括详细的露头和岩心研究的地层和地质岩石特性，严格的地质雷达地球物理测试，包括利用新的方法，最近开创的团队成员，收集岩石物理数据的孔隙几何形状和孔隙度/渗透率的影响，地质雷达反射特性，合成地质雷达建模和流体流动建模。从这个建议的研究和未来的扩展的方法和结果将有助于推进GPR到主流的地球物理方法用于露头研究地层，沉积和流体流动的应用。

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.
