Faults and associated fault zones are key controls on many processes within the brittle upper crust; their individual properties are a controlling factor on the mechanical and fluid transport properties of their protoliths. Despite an impressive volume of work ranging from classic concepts to recent key advances, many features of fault structure and along-strike fault heterogeneity are poorly constrained. This knowledge gap can partially be attributed to outcrop studies that are hindered by a lack of continuous, truly three-dimensional exposures. This work aims to address this paucity in data and presents the preliminary results from an unparalleled dataset comprising LiDAR, photogrammetrically-derived point clouds, wireline geophysics, coal-seam survey data and field observations of fault, and fault-zone architectures. We aim to present preliminary results from a study of fault, and fault zone architecture within mixed siliciclastic and carbonate rocks contained within the Midland Valley basin, Scotland, UK. Three-dimensional fault architecture models have been created using LiDAR, photogrammetrically-derived point clouds and surveyed coal data interpreted in a three-dimensional virtual environment. Models are augmented with measured fault core geotechnical data in order to accurately numerically simulate fluid flow. |
