Swartz, F.M., Rones, Morris, Donaldson, A.C., and Hea, J.P., 1955, Stratigraphy of Ordovician limestones and dolomites of Nittany Valley in area from Bellefonte to Pleasant Gap, Pennsylvania; Trip 1(F), IN Guidebook for the 21st annual field conference of Pennsylvania geologists: Field Conference of Pennsylvania Geologists, no. 21, p. 1-25.


Summary:

Pg. F6, F14, F15 (geol. map). Tea Creek dolomite. At top of Bellefonte group. Consists almost wholly of medium-gray, in part red-flecked dololutite that weathers light, more or less yellowish gray, the weathered surface tending to be deeply gashed by incisions leached along the numerous joints that transect this type of rock. Thickness 200 feet. Includes Dale Summit sandstone member (new) near base. Suggested that Dale Summit sandstone may represent inauguration of Chazyan sedimentation. Underlies Milroy limestone (new). Overlies Coffee Run dolomite (new). Age is Early Ordovician.
Type section: along Tea Creek in Kishacoquillas Valley, [near Reedsville, Brown Twp., Lewistown 15-min quadrangle], Mifflin Co., central PA. [Notable exposures] in area from Bellefonte to Pleasant Gap, Nittany Valley, central PA.
