Abstract

Analysis of sedimentation and thermal data indicates that, for most parts of the Pannonian basin, observed heat flow, thermal gradients, rates of thermal subsidence and vitrinite reflectance are about twice those predicted by assuming a uniform extension model for basin formation in late Miocene time. A modified extension model, whereby large amounts of heat are added to the uppermost mantle during extension (roughly equivalent to replacing the entire sub-crustal lithosphere by asthenosphere), produced results in good agreement with observation and could also account for periods of uplift observed during extension. Crustal extension beneath most parts of the basin is estimated to have been approx 80-170% (beta = 1.8-2.7), although in the deepest parts of the basin (deeper than 4km) crustal extension could have been much greater. Analysis of extension within the Danube and Zala basins indicates that the late Miocene extension in these basins involved the entire lithosphere, but subsidence and heat flow data are not well enough constrained to determine if extra heating is required during extension. On the basis of tectonic and structural data, the Vienna basin has been interpreted as the result of thin-skinned extensional tectonics above a shallow detachment surface within the upper crust.-from Authors
