Reactivated basement structures affecting the sedimentary facies in a tectonically “quiescent” epicontinental basin: an example from NW Switzerland
A Wetzel, R Allenbach, V Allia - Sedimentary Geology, 2003 - Elsevier
The Jurassic deposits in the southern part of central Europe accumulated in a shallow
epicontinental sea, and their deposition has usually been believed to have corresponded to
a phase of tectonic quiescence; neither on conventional seismic records nor in outcrops
obvious indications of synsedimentary tectonics were found. Nonetheless, subtle variations
in lithofacies and thickness occur above faults in the crystalline basement. In fact, preexisting
structures became reactivated in the Jurassic during major extensional phases when the …
