“…The tectonic subsidence of strike-slip basins is mainly episodic, short lived (typically <10 Ma), and end abruptly with commonly very high tectonic subsidence rates (>0.5 km/ Ma) compared to all other basin types (Cloetingh et al 1992Xie and Heller 2009;Allen and Allen 2013). The high tectonic subsidence rates of the late Karpatian time in the Vienna Basin, which was caused by the evolution of the master strike-slip faults, occurred in only short time of c. 0.6 Ma.…”

“…This isolation may well have been the result of isostatic rebound processes which are suggested to have occurred predominantly at the Mediterranean margins (Norman and Chase, 1983) when the sea level dropped drastically at the end of the Yesares Member. These uplift processes probably overprinted the overall pattern of late Cenozoic uplift of the entire region (Cloetingh et al, 1991) and restricted the Sorbas basin from the Mediterranean. We suggest that the restricted position of the Sorbas basin prevented it from extensive erosion during the drawdown of the Mediterranean and favoured the deposition of the continental Zorreras sediments.…”

The Sorbas basin of SE Spain contains one of the most complete sedimentary successions of the Mediterranean re¯ecting the increasing salinity during the Messinian salinity crisis. A detailed cyclostratigraphic study of these successions allows a correlation of the sedimentary cycle patterns to astronomical target curves. Here, we present an astrochronological framework for the Messinian of the central part of the Sorbas basin. This framework will form a solid basis for high-resolution correlations to the marginal carbonate facies and to the Central Mediterranean area.The early Messinian Abad Member contains 55 precession induced sedimentary cycles marked by homogeneous marl±opal-rich bed alternations in the`Lower Abad' and by homogeneous marl±sapropel alternations in the`Upper Abad'. Astronomical tuning results in an age of 5.96 Ma for the transition to the Yesares evaporites and thus for the onset of the`Messinian salinity crisis'. The marl±sapropel cycles of the`Upper Abad' are replaced by gypsum±sapropel cycles (14) in the Yesares Member, indicating that the evaporite cyclicity is related to precession controlled oscillations in (circum) Mediterranean climate as well. As a consequence, gypsum beds correspond to precession maxima (insolation minima) and relatively dry climate, sapropelitic marls to precession minima (insolation maxima) and relatively wet climate. An alternative (glacio-eustatic) obliquity control for evaporite cyclicity can be excluded because the number of sedimentary cycles with a reversed polarity is too high.Sedimentation during the Abad, Yesares, and the overlying coastal sequences of the Sorbas Member, took place in a continuously marine environment, indicating that marine conditions in the Sorbas basin prevailed at least until 5.60±5.54 Ma. According to our scenario, deposition of the Yesares and Sorbas Member took place synchronously with deposition of the`Lower Evaporites' in the Central Mediterranean. Finally, the continental Zorreras Member consists of 8 sedimentary cycles of alternating reddish silts (dry climate) and yellowish sands (wet climate) which correlates very well with the`Upper Evaporites' and Lago Mare facies of the Mediterranean. q

“…For our 2D-numerical modelling of crustal flexure (see e.g., van der Beek and Cloetingh, 1992;Cloetingh et al, 1992;Zoetemeijer et al, 1993), a broken plate model was adopted with the end of a plate marked by the Periadriatic Fault. The position of the Periadriatic Fault is clearly marked in small tonalite lenses (Exner, 1976;Nemes, 1996).…”

The Klagenfurt Basin in the Eastern Alps: an intra-orogenic decoupled flexural basin?

et al. 1997

The Klagenfurt Basin is an E-W-trending narrow Sarmatian to Quaternary flexural basin formed by flexure of the Austro-Alpine lithosphere by loading through the southerly adjacent Karawanken Mountains in the Eastern Alps (Austria). The tectonic evolution of the basin is kinematically connected to Miocene brittle transpressive dextral strike-slip deformation along the Periadriatic Fault which separates the South Alpine unit from the Austro-Alpine unit in the Eastern Alps. The final NW-directed overthrust of the Karawanken Mountains onto the foreland is characterised by a positive flower structure, which is kinematically linked to dextral transpressive shearing along the Periadriatic Fault. Only a small part of the lithosphere appears to support the regional isostatic response to the load by the Karawanken Mountains. The area is characterised by a crustal thickness between 40 and 45 km, elevated heat flow and a strength distribution which suggests that only the upper crust elastically supports the topographic load. Ductile flow of the lower crust is also supported by the absence of a crustal root beneath the Karawanken chain. Rheologic models for this lithospheric configuration indicate a mechanical decoupling of upper crust, lower crust and mantle and generally low strengths for the lower crust and mantle.
