Pg. 43, 44. Battell member of Monastery formation. Black graphitic quartz-muscovite schist with large porphyroblasts of albite. A few lenses of white to gray dolomitic marble occur at base. Beds of porphyroblastic albite-quartz-chlorite-muscovite schist are also associated with this unit. Thickness varies from a featheredge to a maximum of 80 feet. Underlies undivided part of Monastery formation (new); overlies Tyson member (new) of Monastery formation. Age is Early Cambrian.
Named from exposures in Hancock Branch on southeast slope of Battell Mountain, Rochester area, [Bread Loaf 7.5-min quadrangle, Addison Co.], central VT.

The Battell is raised to Formation rank by T.R. Armstrong (in press) [not in bibliography] to describe graphitic schists with carbonates that depositionally overlie the Monastery Formation in the Granville-Hancock area of central VT. The name Battell Formation is tentatively assigned in this report to a distinct group of graphitic rocks with limited occurrence in the study area. The basal portion of the Battell is assigned by Armstrong to the White River Member (new name) and following that nomenclature, the White River is the only part of the Battell seen in the Fayston-Buels Gore area. The White River appears to be in fault contact with the Underhill Formation along the eastern boundary of the Underhill in Buels Gore. The member also appears to be in depositional contact with the Monastery Formation at all observed locations and occurs as small bodies within the schists of the Monastery.
