Summary:
Pg. 276-278 and map. Whitingham schist. Quartz-biotite schist with calcite; nearly half the rock is quartz in small even grains, and nearly half is even-grained biotite. Calcite occurs in crystals in many parts of the rock. Is believed to be of sedimentary origin. Thickness 40 to more than 100 feet. Immediately overlies Sherman marble, with gradation from the marble to the schist through several feet of rock. Underlies Heartwellville schist, into which it passes through a transition zone 5 to 20 feet thick. Assigned to Ordovician through correlation of associated formations with those of Massachusetts.
Named from exposures in Whitingham Twp., Windham Co., southeastern VT.
