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 ... -

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
Richter, Peter P.; Ring, Uwe; Willner, Arne P.; (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 ... -
Structural control of fluid flow on a carbonate platform margin: an example from the Otavi Mountainland, Namibia
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The present study focuses on the northwestern OML, southwest of the mining town of Tsumeb. The dominating structure in this area is the NW-SE striking Guinas Fault. The Guinas Fault is a shear zone that divides an area, ... -
Structural investigation and strain analysis of a polyphase flower structure in the Lower Saxony Basin, Germany
Wagner, Lars; Lohr, Tina;; ; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
The Lower Saxony Basin (LSB) is a part of the post-Variscan Central European Basin System. We used a 3-D reflection seismic dataset in the northern LSB, provided by RWE-DEA AG, Hamburg (c.f. Lohr et al. submitted) for our ... -
Structural investigations of the W termination of the ‘Schneeberg Zug’ — Austroalpine Unit, Southern Tyrol: Results from a crustal scale shear zone
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Austroalpine microplate traces the Alpine collision event between the Africa-related southern Alpine realm and the European continent. The southern margin of this microplate, the basement to the north of Meran ... -
Structural record of an oblique impact: the central uplift of the Upheaval Dome impact structure, Utah, USA
; ; Jahn, Andreas (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Most asteroids strike their target at an oblique angle (Pierazzo & Melosh 2000). The common criterion for identifying craters formed by an oblique impact is the pattern of the ejecta blanket. On Earth, however, ejecta ... -
