Die neogene Entwicklung des zentralen Tien Schan, Kasachstan. Erste Ergebnisse von Apatit-Spaltspurdatierungen und morphotektonischer Analyse von Satellitendaten
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Der Tien Schan ist ein etwa E–W erstrecktes,
rund 2500km langes und bis 250km breites Gebirge in Zentralasien.
Einzelne Gipfel sind über 7000m hoch.
Obwohl durch die Kollision Indiens mit
Asien entstanden, ist der Tien ...
Deformation mechanisms in the eastern Sudbury Igneous Complex, Canada: Evidence for meteorite impact into an active orogen
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The 1.85 Ga Sudbury Igneous Complex (SIC) in central Ontario is now widely considered to be the erosional remnant of a deformed paleo-horizontal impact melt sheet, about 2.5 km in thickness. Deformed impact melt breccias ...
Evolution of the Tamtsag Basin / NE-Mongolia — part II: structure and hydrocarbon potential
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The Tamtsag basin in NE Mongolia is
part of a widespread basin system which
formed during Late Jurassic and Cretaceous
times (Graham et al. 2001,
Qing-Ren et al. 2003). It is filled
with continental sediments and volcanics
which ...
Microstructural evidence of impact-induced crystalplastic deformation and postshock annealing of quartz
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
During impact, rocks at the surface
and accessible depths encounter extreme
conditions. The hydrostatic component of the shock wave-associatedstress, the so-called shock pressure, canreach several tens of GPa in the central ...
Effect of crystallography and temperature on the development of quartz high-angle grain boundaries in metamorphic rocks
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Grain boundary migration during dynamic
recrystallization of quartz results
in grain boundary suturing of various
extent. The geometry of the sutured
boundaries is affected not only by temperature,
strain rate, finite ...
Neotectonic markers in the Panafrican belt formations of Cameroon: elements of interpretation and their environmental impacts
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
The North equatorial Panafrican Belt,
whose Cameroonian formations are
dated between 650 and 400 million
years, and which are located in the
North of the Congo Craton, is subdivided
in to three major geodynamic domains:
a ...
Mikrostruktur und Textur nach Scherverformungsversuchen an Hämatiterzen
(
- 11. Symposium "Tektonik, Struktur- und Kristallingeologie"
, 2006-03)
Die Beziehungen zwischen der Mikrostruktur
und der kristallografischen
Vorzugsorientierung (Textur) von Hämatiterzen
der gebänderten Eisenerzformation
(BIF) in Brasilien wurden in vielen
Veröffentlichungen behandelt, ...
Structural investigation and strain analysis of a polyphase flower structure in the Lower Saxony Basin, Germany
(
- 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 ...
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 ...
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 ...
