| Description | The boreholes Gottwaldov 1 a 2 (G1 and G2) are comparable boreholes in the prospection area of Vizovice Hills (Fig. 1). A 1D model of subsidence and the thermal history of the G1 and G2 boreholes were created in order to determine boundary conditions, heat flow, and paleo water depth (Fig. 2 and 3). The measured vitrinite reflectance (% Rr) and the stabilized temperature data measured during pumping tests were used as independent calibration parameters. The model input data represent geological expectations such as paleogeographical reconstructions, paleo water depth scenario (Fig. 2), and basin tectonic evolution. The basal heat flow (HF) was created using the McKenzie scenario (1978) and respects the typical HF values published by Allen –Allen (2006). HF values were manually decreased by 3 mW/m2 to reflect thrusting according to the model scenario (Gusterhuber et al. 2013). The recent HF values ranging from 38 mW/m2 (G1) and 41 mW/m2 (G2) (Fig. 3). The resulting model represents the best fit HF scenario and two alternative HF scenarios. The best fit HF scenario from multi 1D approach was used to verify 2D burial history modelling (Fig. 4). The 2D cross section modelling was calibrated using similar calibration parameters as those used in 1D modelling. |
