Short summary
This research is part of a PhD thesis examining evaporite detachments characteristics. 40Ar/39Ar geochronology is employed to constrain the timing of formation and deformation events. A diagenetic age of ~514 Ma is interpreted from the oldest significant step age. Other step ages may represent a Cambrian–Permian deformation event or a complex mixing age of diagenetic Ar with partially reset Ar during the Cenozoic. We report the first closure temperature for polyhalite between 254 and 277 °C.
