Halite lying above the potash-rich interval of the Permian Upper Evaporite Group of northeast Yorkshire, England, is intimately associated with fine red clastics in such a way as strongly to suggest that the former originated by nucleation and growth within the latter. It is inferred that this process took place in distal sediments of a mature basin-margin plain, probably in a belt subject to repeated inundation caused by periodic large-scale expansions and contractions of an extensive basin-centre playa. Such an environment is consistent with the generally shallow-water to continental origin of the underlying Carnallitic Marl and the overlying Permian Upper Marls, and contrasts with the deep-basin depositional model customarily applied to the Zechstein evaporites.
