Netop Formation - phyllite, dolostone and dolomitic quartzite

Dark-gray phyllite containing bluish-gray dolostone and tan-weathering to locally mappable gray-weathering dolomitic quartzite. The Netop Formation may be in part equivalent in age and facies to parts of the West Castleton and Hatch Hill Formations, but may extend lower and into the Neoproterozoic. Rocks of the Dorset Mountain slice (includes Dorset Mountain proper and Mount Equinox, southward to West Mountain near Bennington). Part of the Taconic Allochthon.
