“…Laminated lower crust revealed by refraction/reflection profiling in the western BM, and mostly in its ST part (DEKORP Res. Group, 1994;Hrubcová et al, 2005), supports such detachment along a ductile zone in the lower crust, observed also in several west European regions (Müller et al, 1997). The latter authors suggest that a weak constant shear stress develops in the lower crust due to a differential velocity of the motion between the brittle upper crust and the mantle lithosphere.…”

“…The stress pattern is driven and altered by several stress sources; they are discriminated depending on the scales into first-order (> 500 km), second-order (100-500 km) and third-order stress sources (< 100 km) (Heidbach et al, 2007Müller et al, 1997;Tingay et al, 2005;Zoback, 1992;Zoback and Mooney, 2003). First-order stress sources as the main driving forces are summarized as plate boundary forces, which are ridge push, slab pull, and trench suction, gravity and basal drag by mantle convection.…”

Abstract. In the context of examining the potential usage of safe and sustainable geothermal energy in the Alberta Basin, whether in deep sediments or crystalline rock, the understanding of the in situ stress state is crucial. It is a key challenge to estimate the 3-D stress state at an arbitrarily chosen point in the crust, based on sparsely distributed in situ stress data.To address this challenge, we present a large-scale 3-D geomechanical-numerical model (700 km×1200 km×80 km) from a large portion of the Alberta Basin, to provide a 3-D continuous quantification of the contemporary stress orientations and stress magnitudes. To calibrate the model, we use a large database of in situ stress orientation (321 S Hmax ) as well as stress magnitude data (981 S V , 1720 S hmin and 2 (+11) S Hmax ) from the Alberta Basin. To find the best-fit model, we vary the material properties and primarily the displacement boundary conditions of the model. This study focusses in detail on the statistical calibration procedure, because of the large amount of available data, the diversity of data types, and the importance of the order of data tests.The best-fit model provides the total 3-D stress tensor for nearly the whole Alberta Basin, and allows estimation of stress orientation and stress magnitudes in advance of any well. First-order implications for the well design and configuration of enhanced geothermal systems are revealed. Systematic deviations of the modelled stress from the in situ data are found for stress orientations in the Peace River and the Bow Island Arch as well as for leak-off test magnitudes.

“…Magnetostratigraphic and palaeobotanical data suggest that the syn-rift deposition in Eger Rift basins ended during the early Miocene [64]. The post-rift evolution of the Eger Rift is associated with a NW-to NNW-trending compression [65,66]. This compression resulted in the post-early Miocene uplift and tilting of the Ore Mountains' metamorphic complex [52,67].…”

DEM-Based Analysis of Interactions between Tectonics and Landscapes in the Ore Mountains and Eger Rift (East Germany and NW Czech Republic)

Tectonics modify the base-level of rivers and result in the progressive erosion of landscapes. We propose here a new method to classify landscapes according to their erosional stages. This method is based on the combination of two DEM-based geomorphic indices: the hypsometric integral, which highlights elevated surfaces, and surface roughness, which increases with the topographic elevation and the incision by the drainage network. The combination of these two indices allows one to produce a map of erosional discontinuities that can be easily compared with the known structural framework. In addition, this method can be easily implemented (e.g., in MATLAB) and provides a quick way to analyze regional-scale landscapes. We propose here an example of a region where this approach becomes extremely valuable: the Ore Mountains and adjacent regions. The lack of young stratigraphic markers prevents a detailed analysis of recent fault activity. However, discontinuities in mapped geomorphic indices coupled to the analysis of river longitudinal profiles suggest a tight relationship between erosional discontinuities and main tectonic lineaments.Remote Sens. 2014, 6 7972
