Oligocene emplacement of the Eclogite Zone of the central Tauern Window, Eastern Alps, Austria
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The EZ is an approximately 20km long and 2–3km wide coherent unit of the Tauern Window in the Eastern Alps. It is sandwiched between the Venedigerand the Glockner Nappe. While rocks in the EZ experienced HP metamorphic conditions ... -
Origin of Central Andean collapse calderas
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Regional strains in tectonically active volcanic provinces may have a profound influence on the mode of collapse caldera formation. Conversely, the deformation pattern, more specifically, the symmetry of plan-view strain ... -

Perturbation of isotherms below topography: constraints from tunnel transects through the Alps, Gotthard road tunnel
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)For many years it has been known that near surface isotherms are influenced by the topography (Lees 1910). Recently, a number of studies were pursued to quantify the effect of topography on low temperature isotherms ... -
Quantification and sensitivity of fault seal parameters demonstrated in an integrated reservoir modelling work flow. A case study on the Njord Field, Halten Terrace, Norway
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The primary objective of this paper is to present a fault seal case study from the Njord Field, offshore Norway. The study utilised analogue field studies as well as core descriptions and petrophysical well data in order ... -
Quartz microstructures in nature and experiment — evidence of rapid plastic deformation and subsequent annealing
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Quartz microstructures produced in short-term deformation and annealing experiments are compared with those in naturally deformed vein quartz in cores from the Long Valley Exploratory Well (Long Valley Caldera, California). ... -
Regional fold structure analysis in the Eastern Alpi Apuane, Northern Apennine
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Alpi Apuane represent a large tectonic window within the Northern Apennine in Italy. In this area, not only a complete succession of the tectonic units of the Northern Apennine can be studied, but also the structures that ... -
Relevance of viscous flow in accretionary wedges
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The orogenic wedge model (Davis et al. 1983; Platt 1986) marks a conceptual breakthrough in understanding the growth and long-term evolution of accretionary wedges. The characteristic rheology of subduction-related ... -
Remote Sensing Analyses of Neotectonic Active Regions in East-Kamchatka
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The tectonic history of the Kamchatka Peninsula is dominated by continuous accumulation and amalgamation of terranes with different origins, which were delivered by convergence between the Pacific plate and in former times, ... -
Rock fabrics in palaeoweathering profiles below basement-cover interfaces (AMS-study on drill cores from the Caledonian margin, Central Sweden)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Basement-cover-interfaces are important crustal boundaries. In many cases they act as detachment horizons. Criteria like pre-erosional basement characteristics, intensity of palaeoweathering and post-erosional processes during ... -
Scherzonen- und Schuppenbildung am Kontakt von im Bereich der Engelhörner, Berner Oberland (Schweiz)

Separation of magnetic subfabrics by high-field, lowtemperature torque measurements
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The anisotropy of magnetic susceptibility (AMS) can serve as a good indicator of strain in deformed carbonate rocks with diamagnetic susceptibility (Owens and Rutter 1978; de Wall 2000). However, the magnetic fabric due ... -
Strain Localisation, Fracturing and Hydrothermal Mineralisation: Numerical Models of the Mount Isa Copper Deposit, Australia
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006)There is substantial need in mineral exploration to understand the structural controls on ore deposition for these types of deposits in order to predict the localities of new ones. Application of basic principles of rock ... -
Structural contacts in the Late Paleozoic accretionary wedge of central Chile and their tectonic significance for the evolution of the accretionary complex
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Chilean accretionary wedge is part of a Late Paleozoic subduction complex that developed during subduction of the Pacific plate underneath South America. The wedge is commonly subdivided into a structurally lower Western ... -
