Browns Pond Formation of Rowley and others (1979)

Gray to black slate, punky-weathering calcitic wacke and mudstone, and thin limestone breccia in part equivalent to the West Castleton Formation. Shown only in the Granville, N.Y., area. Locally purple and green slate above black slate of the Browns Pond is interpreted as a lens of the Mettawee slate facies in the Bull Formation. Rocks of the Giddings Brook, Sunset Lake, and Bird Mountain slices. Part of the Taconic Allochthon.
