“…The second model differs by the presence of a 3.0‐km thick top layer with material parameters typical for sedimentary rocks: density of 1.7 g/cm 3 and thermal conductivity of 1.0 W m −1 K −1 , that is, considerably decreased relative to the underlying layers. Low values of thermal conductivity (≤1.5 W m/K) are typical for high‐porosity sedimentary rocks (Eppelbaum et al, ).…”

Thermochronology and Exhumation History of the Northeastern Fennoscandian Shield Since 1.9 Ga: Evidence From ⁴⁰Ar/³⁹Ar and Apatite Fission Track Data From the Kola Peninsula

Results from thermochronological studies have multiple applications to various problems in tectonics and landform evolution. However, up to now a lack of thermochronological data from the northeastern Fennoscandian Shield has complicated the interpretation of tectonothermal evolution of the region. Here, we use both new and previously published multimineral 40Ar/39Ar data (amphibole, mica, and feldspar) on the various Precambrian magmatic and metamorphic complexes to reconstruct the thermal history of NE Fennoscandia within the Kola Peninsula area in the interval 1900–360 Ma. Using the apatite fission track method as well as a numerical model of the heating‐cooling process of northeastern Fennoscandia's upper crust, we have reconstructed its thermal evolution for the interval 360–0 Ma. According to our model, since Lapland‐Kola orogenesis (1930–1905 Ma) northeastern Fennoscandia experienced a quasi‐monotonous cooling with the average rate of ~0.15 °C/Myr, which is equal to an exhumation rate of ~1–2 m/Myr. New apatite fission track data and time‐temperature modeling reveal a “hidden” endogenous thermal event in the NE Fennoscandia that took place between 360 and 300 Ma. This we attribute to an elevated geothermal gradient due to Baltica's drift over the African large low shear‐wave velocity province in the lowest mantle and/or thermal blanketing by insulating Devonian‐Carboniferous sedimentary/volcanic cover. Our model is further supported by evidence of Late Devonian‐Carboniferous rifting in the East and South‐Western Barents Basin, as well as various 360–300 Ma magmatic events within SW Fennoscandia and the Baltic countries.

The hummocky Balaton Highland is located in western Hungary and is part of the Transdanubian Mountains, the most extensive carbonate aquifer system in Hungary. The study region also encompasses Lake Balaton, the biggest lake in central Europe, which is to the south of Balaton Highland. The surface water–groundwater interaction in the Balaton Highland–Lake Balaton region and the groundwater contribution to Lake Balaton are revisited in this paper. Hydrostratigraphic classification was performed first; then, groundwater flow directions by hydraulic head distribution were analysed, and baseflow indices of surface watercourses were calculated. Regarding hydrochemical characterisation, general hydrochemical facies were identified, natural tracers of temperature, chloride and uranium were applied, and the stable isotopic composition of oxygen and hydrogen was determined. Finally, groundwater flow and heat transport were simulated in a 2D numerical model. A high level of hydraulic interaction was evidenced between surface water and groundwater and the sub-regions of Bakony Mountains, Balaton Highland and Lake Balaton by physical and chemical parameters, numerical simulation and groundwater-flow-related natural manifestations, revealing hydraulic continuity in the study region. Based on the results, the division of legislative water bodies can be reconsidered, especially that surface water and groundwater should be regarded as interconnected, and Lake Balaton can be considered a groundwater-dependent ecosystem in any water-use planning in the region.
