“…The integrated model of the lithospheric thickness (Fig. 10) is based on P-wave seismic tomography models (Spakman, 1990;Kissling and Spakman, 1996;Bijwaard and Spakman, 2000;Piromallo and Morelli, 2003), surface-wave tomography models (Panza et al, 1986;Calcagnile, 1991;Du et al, 1998;Shapiro and Ritzwoller, 2002;Boschi et al, 2004), P-wave residuals (Babuška and Plomerová, 1992), thermal models (Balling, 1995;Cermak and Bodri, 1995;Artemieva, 2003), magnetotelluric studies (Ádám et al, 1982;Jones, 1984;Praus et al, 1990) and P-T data for mantle xenoliths (Coisy and Nicolas, 1978;Kukkonen and Peltonen, 1999).…”

“…The thickness of the lithosphere was estimated to 80–100 km by Horváth (1993), based on seismic data, to 80–90 km by Stănică et al (1986), based on magnetotelluric sounding, and to 90–100 km, by Demetrescu et al (1984), based on geothermal calculations. In contrast, the lithosphere is thinner in the Pannonian Basin (50–60 km, Ádám 1976; Ádám et al 1982; Horváth 1993) and thicker in the Carpathians and their foreland (∼180–200 km, Stănică et al 1986; Demetrescu et al 1984; Rădulescu et al 1985).…”

Summary This paper investigates the heat‐flux budget of the Transylvanian Basin along a 240 km long WNW–ESE geological profile. The thermal effects of sedimentation, erosion, crustal heat production and mantle heat flux on the thermal structure are studied. The thermal modelling is based on a 2‐D finite‐element model, which includes the effects of changing sedimentation rates, vertical and lateral variations in sediment thermal parameters, sediment compaction, as well as lateral variations in the crustal heat production and mantle heat flux. Even though the sedimentation history of the Transylvanian Basin began in Senonian time (90 Ma) and the total sediment thickness in the centre amounts to 8 km, half of the sediment cover was deposited in Neogene times from 16.2 to 5.6 Myr. The uplift and erosion of the basin began 5.6 Ma, resulting in a present‐day average elevation of ∼600 m. The surface heat‐flux pattern exhibits low values of ∼30 mW m−2 in the middle of the basin and higher values of ∼60 mW m−2 towards the margins. The low heat flux is explained by a combination of a depletion in crustal heat production, contributing with ∼15 mW m−2, and a relatively low mantle heat flux. The present‐day transient heat‐flux depression caused by the rapid Neogene depositional history and the subsequent thermal relaxation (5.6–0 Ma) amounts to ∼2.5 mW m−2. Lateral variation of the heat flux at the base of the lithosphere cannot produce the surface heat‐flux anomaly.

Lithospheric structure of Central Europe: Puzzle pieces from Pannonian Basin to Trans‐European Suture Zone resolved by geophysical‐petrological modeling

We have analyzed the thermochemical structure of the mantle in Central Europe, a complex area with a highly heterogeneous lithospheric structure reflecting the interplay of contraction, strike slip, subduction, and extension tectonics. Our modeling is based on an integrative 3‐D approach (LitMod) that combines in a self‐consistent manner concepts and data from thermodynamics, mineral physics, geochemistry, petrology, and solid Earth geophysics. This approach minimizes uncertainties of the estimates derived from modeling of various data sets separately. To further constrain our 3‐D model we have made use of the vast geophysical and geological data (2‐D and 3‐D, shallow/crustal versus deep lithospheric experiments) based on experiments performed in Central Europe in the past decades. Given the amount and the different nature/resolution of the available constraints, one of the most challenging tasks of this study was to consistently combine them, finding a trade‐off between all local and regional data sets available in a way that (i) preserves as many structural details as possible and (ii) summarizes those data sets into a single robust regional model. The resulting P/T‐dependent mantle densities are in LitMod 3‐D calculated based on a given mineralogical composition. They therefore provide more reliable estimates compared to pure gravity models, which enhance modeling of the crustal structures. Our results clearly indicate presence of several lithospheric domains characterized by distinct features, Pannonian Basin being one of the most outstanding ones. It has the thinnest crust and lithosphere in the area modeled, characterized by relatively fertile composition.
