Summary:
Named in this report as basal unranked unit (of 3?) of Admire? formation (major natural division IX) of Pennsylvanian beds in southeastern NE, Forest City basin. No type locality given. Probably named for town of Brownville, Nemaha Co, NE. In Missouri River section, occurs in bluffs between Honey Creek valley near Peru and 4 mi southeast of St. Deroin where limestone is light bluish green, weathering lighter and is 2 ft 6 inches to 6 ft thick; upper part is somewhat nodular, lower part massive. In Big Nemaha section, is not well exposed at many places in Big Nemaha valley. In section taken in slopes east of Lehmer quarry, sec 32, T1N, R16E, or 3 mi south and 1 mi west of Falls City, consists of: blue-gray, buff-weathering limestone 2 ft thick in one bed, quite fossiliferous in upper part, hard; shale and weathered limestone, 7 inches thick, shale bluish; and dark-blue, blocky, fossiliferous limestone 8 inches thick. Overlies McKissock Grove shales (major division VIII); separated from overlying Aspinwall limestone [member; unranked by authors] (new) of Admire? formation by 12-20 ft of unnamed shale. Cross sections.

Summary:
Revised as basal bed (of 4) of Admire shale member of Wabaunsee formation in the Forest City basin. Consists of two grayish limestones separated by a thin shale; total thickness is 3 to 5 ft. Generally, top limestone is the thinner. Both limestones weather yellowish or brownish; lower one forms rounded blocks. Overlies Pony Creek shale [bed] (new) of McKissick Grove shale member of Wabaunsee formation; underlies Aspinwall shale [bed] of Admire shale member of Wabaunsee formation. Cross sections; measured sections; geologic maps; stratigraphic tables. Crinoid joints, common; RHOMBOPORA LEPIDODENDROIDES and few fenestrated bryozoans, common; LOPOPHYLLUM PROFUNDUM, rare; BUCANOPSIS sp., rare; several brachiopods (MARGINFERA SPLENDENS most noticeable); pelecypods, rare.
