Demonstrating large-scale cooling in a Variscan terrane by coupled groundwater and heat flow modelling

•Examination of heat flow density anomalies via coupled groundwater and heat flow models.•Karst system and fault zone cooling effects are superposed on slower pervasive groundwater flow.•Cooling affects the Variscan thrust nappe under investigation at depths of up to 2–3km.•Groundwater cooling occur...
