Abstract
Corrensite, a regularly-interstratified mixed-layer chlorite-vermiculite, has been detected in four samples taken from just below the Hutchinson Salt Member of the Wellington Formation at depths ranging from a few meters (less than ten feet) to about 30 meters (about 100 feet) below the base of the salt. The corrensite is intermixed with illite and chlorite as well as non-clay minerals such as gypsum, anhydrite, halite, quartz, and dolomite. This represents a new occurrence of corrensite in association with an evaporite sequence and reinforces the view that corrensite is formed in (hyper-) saline environments.
