Evaluation of eroded Mesozoic formations in northern Alsace (France) using organic eochemistry and basin thermal modelling
Abstract
In the URG, the terminal Jurassic and Cretaceous formations are missing. It remains uncertain whether their absence is related to a sedimentary hiatus or a period of erosion. The geochemical analyses of the Jurassic outcrops of Pechelbronn area show that the Mesozoic formations are immature. It suggests that these deposits were not sufficiently buried before the Cretaceous. By using molecular markers, vitrinite reflectance, kinetic properties of source rocks, artificial maturation and 1D thermal basin models, we can estimate a maximum paleo-burial, evaluate the heat flux and simulate the oil generation.
