Summary:

Named the Fairfield member of the Underhill formation of the Camels Hump group for Fairfield Pond, northern VT. Name was first used by Dennis (1961; New England Intercoll. Geol. Conf. Guidebook, Oct. 13-15, 53rd Annual Mtg.). Consists of greenish quartzitic schist (quartz-sericite-albite-chlorite-biotite) and sericite-quartz-chlorite phyllite; locally purple or red. The Fairfield is of Early Cambrian age.

Summary:

Raised the Fairfield Pond to formation rank in west-central VT. Overlies the Late Proterozoic Pinnacle Formation and underlies the Lower Cambrian Cheshire Formation. The Fairfield Pond is therefore considered of Late Proterozoic age.

Summary:

Age of the Fairfield Pond Formation changed to Late Proterozoic and Early Cambrian based on correlation with Moosalamoo Member of Mendon Formation in west-central VT and West Sutton Formation in northern VT (study area in central VT).
