Application of Lidar to resolving tectonic and glacial fabrics in glaciated terrain: An example from an Archean granite-greenstone belt, northeastern Minnesota

Abstract: In this study we examine an Archean granite-greenstone terrane in northeastern Minnesota (USA) to illustrate the application of high-resolution Lidar (light detection and ranging) altimetry to mapping regional tectonic fabrics in forested glaciated areas. We describe the recognition of lineaments and distinguish between tectonic and glacial lineament fabrics. We use a 1-m Lidar derived bare earth digital elevation model to construct multiple shaded-relief images for lineament mapping with sun elevation of 45° … Show more

“…This terminology, however, is misleading because MVS is not limited to closerange (≤300 m from camera to object) modeling (Wolf and Dewitt, 2000). Other studies have used airborne lidar over large areas to resolve bedrock structure where outcrop is poor (e.g., Pavlis and Bruhn, 2011;Dyess and Hansen, 2014) using subtle topographic features to track compositional layering. Studies by Svennevig et al (2015) and Tavani et al (2014) are important examples where researchers experimented with full 3-D mapping procedures, in which geologic features were interpreted with 3-D polylines and structural information was extracted from models of map-scale outcrops.…”
