The Cambrian Hardyston Formation or Hardyston Quartzite is a mapped bedrock unit in Pennsylvania and New Jersey.
It was originally described by Wolff and Brooks in 1898,[1] where two outcrops in Hardyston Township, Sussex County, New Jersey, were described. They originally named it the Hardistonville quartzite, but the name was later changed by Kummel and Weller in 1901 to Hardiston quartzite,[2] and changed again by the same authors a year later to Hardyston quartzite.[3]
