This study aims to clarify the timing of the Jurassic thermal pulse(s) and its potential to heat the Mesozoic sediments, which covers the Palaeozoic basement. Especially, the temperatures and geothermal-gradients that were reached are of mayor interest. During a hydrothermal period is convective heat transport the important mechanism, which influences the reached temperatures in the upper crust. Therefore, addresses a localised detail study at the URG main border fault the potential of fault-bounded thermal anomalies caused by ascending hot fluids to heat the surrounding rocks.
The FT method, which is the base method used here, is a low-temperature thermochronological method widely used to quantify the thermal history of igneous, metamorphic and clastic sedimentary rocks. In particular, the FT analyses of detrital samples provide the advantage to discriminate between a pre-depositional thermal history of the provenance regions and a post-depositional basin related thermal history (e.g. Brandon 1998, Carter 1999, Bernet & Garver 2005, Armstrong 2005).
The FT analyses oft the Permian and Mesozoic sediment column in the URG area, this study, compared with previous FT studies from the Black Forest and the Vosges (Michalski 1988, Wyss 2000, Timar-Geng et al. 2004, 2006a, b) led to a complete overview of the FT age signatures of URG pre-rift units. This is a requirement for the interpretation of Cenozoic detrital syn-rift deposits of the region by the FT method. New FT analyses on Cenozoic samples from the southern URG area led to basal insights in the syn-rift river drainage patterns.
