In Germany, claystones are studied for their suitability as host-rocks for the disposal of high-level radioactive waste. The MATURITY project systematically investigates how gradual burial affects key barrier properties in the Lower Jurassic Amaltheenton Formation of the Lower Saxony Basin (Germany). Understanding these changes helps assess claystone suitability for long-term waste isolation, improving site selection for deep geological repositories.

This study analyzes geological faults using triangular surface data to model displaced horizons, considering scenarios with and without elevation uncertainties. Formal proofs and computational experiments show that without elevation errors, identical dip directions occur. Even with uncertainties, the expected dip direction remains consistent. The findings offer insights for predicting fault geometry in data-sparse environments, improving fault modeling with imprecise elevation data.
