The basal heat flow is the most important quantity determining the thermal evolution within a sedimentary basin. Commonly, it is calculated by inversion from vitrinite reflectance and temperature data for a basin model. Unfortunately, this procedure does only cover the younger geologic history of the earth. However, heat flow can be estimated through knowledge of stretching time and factors in rift basins for paleo times. If the type of rifting and its timing is known, it is possible to calculate the stretching factors by inversion of subsidence from the basin model. Heat flow calibration
can thus be subdivided into two parts. Firstly, an overall heat flow is calculated by crustal modeling and secondly it is calibrated against
well
data. An integrated workflow with a consistent and efficient employment of these steps is demonstrated for a case study. The details are given by the following specifications:
