Electromagnetic radiation (EMR) and its interpretation in terms of stresses in the lithosphere
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Electromagnetic radiation (EMR) as measured at the surface of the lithosphere or underground shows preferred orientations, which can be related to microcracks and other brittle structures at micro and nano scales (see Bahat ... -
Empirische Feldstudien über elektromagnetische Emissionen in Gesteinen unter aktiven Krustenspannungen
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)In den vergangenen Jahren wurden von den Mitgliedern unseres Departments mehrere Feldstudien über elektromagnetische Emissionen in tektonisch aktiven Regionen durchgeführt. Die Untersuchungsgebiete lagen in Südspanien, ... -
Evolution and structure of the Upper Rhine Graben — quantitative insights from numerical modelling approaches
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Upper Rhine Graben forms the major segment of the Cenozoic Rift system of Western Europe. Although the rift was the target of many seismic and geological investigations, the style of lithospheric extension below the ... -
Experimental study of the evolution of fault gouge in layered sand–clay sequences
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)This study focuses on clay smear processes during fault gouge evolution in sand-clay sequences at depths up to 2 km. A clay-rich fault gouge can dramatically lower the fault’s permeability, and prediction of this process ... -
