Nominal Re-Os ages of the studied Hekkingen Formation range from 153.3 to 148.6 Ma. Multiple evidence identifies reverse faulting, perhaps related to gravity glides. Trace metal geochemistry indicates bottom water euxinia with 100% DOPT. Geochemical data restored to pre-faulting order reveal two pyrite-rich events. Regional comparison reveals later onset of deposition of Hekkingen shales at Skalle.
