Ferron Formation

The Ferron Formation is a geologic formation in Utah. It preserves fossils dating back to the Cretaceous period.

Named by Lupton (1916), the formation is readily divisible into upper and lower members on the basis of both lithologic character and depositional history. Tectonic rejuvenation of adjacent provenance areas near the present Mount Nebo and Fish Lake Plateau shed coarser clastics eastward into the shallow seaway. This resulted in deposition of the widespread and persistent basal regressive marine sandstone of the Ferron.
