Beziehung zwischen Tektonik und Zementation in den Nördlichen Kalkalpen und ausgewählten Gebieten im Mittel- und Unterostalpin
Untersuchungen von Karbonatzementen in tektonischen Störungen sowie assoziierten Klüften in den Nördlichen Kalkalpen und im Mittel- und Unterostalpin geben Auskunft über die zeitliche Einordung von tektonischen Bewegungen und Zementation im Zeitraum Trias bis Miozän. Grundlage ist eine …

Magnetotelluric measurements across the southern Barberton Greenstone Belt, South Africa
… Erde eine Rolle spielten oder ob vertikale Tektonik, angetrieben durch die im Archaikum höheren Temperaturen, die Bildung der heutigen Kontinente bestimmt hat. Um neue Erkenntnisse über die interne Struktur und Entwicklungsgeschichte des BGB zu erhalten, wurden im Rahmen der …

Tectonic and climatic forcing in orogenic processes : the foreland basin point of view, Alborz mountains, N Iran
… wiederspiegelt. Um die Effekte von Klima und Tektonik in einem solchen System zu erforschen, untersuchte ich die Oligo-Miozänen Sedimente in den Vorlandbecken der südlichen Elburs Bergkette, einem intrakontinentalen Gebirge in Nord-Iran, das im Zuge der Arabisch-Eurasischen Kontinent-Kollision …

The tectonic evolution of the western Tien Shan
Intracontinental deformation usually is a result of tectonic forces associated with distant plate collisions. In general, the evolution of mountain ranges and basins in this environment is strongly controlled by the distribution and geometries of preexisting structures. Thus, predictive models …

Late Pleistocene-Holocene sedimentary processes at the active margin of South-Central Chile : marine and lacustrine sediment records as archives of tectonics and climate variability
Active continental margins are affected by complex feedbacks between tectonic, climate and surface processes, the intricate relations of which are still a matter of discussion. The Chilean convergent margin, forming the outstanding Andean subduction orogen, constitutes an ideal natural laboratory …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
In north-western Namibia the fills of the Karoo-Etendeka depositories can be subdivided into (1) a Carboniferous-Permian, (2) a Triassic-Jurassic and (3) a Cretaceous megasequence, each recording extensional periods related to successive rifting phases in the evolving South Atlantic. The tectonic …

Pliocene-Pleistocene landscape evolution in south-central Chile : interactions between tectonic, geomorphic, and climatic processes
Landscapes evolve in a complex interplay between climate and tectonics. Thus, the geomorphic characteristics of a landscape can only be understood if both, climatic and tectonic signals of past and ongoing processes can be identified. In order to evaluate the impact of both forcing factors it is …

Structural observations at the southern Dead Sea Transform from seismic reflection data and ASTER satellite images
Die folgende Arbeit ist Teil des multidisziplinären Projektes DESERT (DEad SEa Rift Transect), welches seit dem Jahr 2000 im Nahen Osten durchgeführt wird. Dabei geht es primär um die Struktur der südlichen Dead Sea Transform (DST; Tote-Meer-Transformstörung), Plattengrenze zwischen Afrika (Sinai) …

Detection and Kirchhoff-type migration of seismic events by use of a new characteristic function
The classical method of seismic event localization is based on the picking of body wave arrivals, ray tracing and inversion of travel time data. Travel time picks with small uncertainties are required to produce reliable and accurate results with this kind of source localization. Hence recordings, …

Modelling surface evolution coupled with tectonics
This study presents the development of 1D and 2D Surface Evolution Codes (SECs) and their coupling to any lithospheric-scale (thermo-)mechanical code with a quadrilateral structured surface mesh. Both SECs involve diffusion as approach for hillslope processes and the stream power law to reflect …
