Burr limestone member of Grenola formation. The newly established Grenola formation is divided into following members (descending): Neva limestone, Salem Point shale, Burr limestone, Legion shale, and Sallyards limestone. The salient lithologic feature of Burr member is its lamination. It is calcareous throughout and has a carbonaceous shale in the middle to north. Is of nearshore marine origin. Averages about 11 feet in thickness from Roca, [Lancaster County], Nebraska, to Burbank, [Osage County], Oklahoma, disregarding the abnormal Pawnee County, Nebraska, section. The upper Burr in Nebraska is light gray, with an extremely dense, carbonaceous lime cap that covers an ostracodal zone. The middle Burr in Nebraska, and northern Kansas is black or brownish shale containing abundant plant remains. The lower Burr in Nebraska consists of 1, 2, or 3 limestones separated by shale, and farther south it is irregular, shaly, and nodular with dark-gray mottling, and weathers platy or shattered.
Type locality: the bluffs and ravines west of South Fork of Little Nemaha River, in sec. 20, at point 0.25 mi west of north-south road, 2.5 mi northwest of Burr, Otoe Co., NE.

Pg. 8. Burr limestone member of Grenola formation of Council Grove group. Consists of (descending): (1) gray massive limestone, 3.5 to 4 feet; (2) gray and black shale, 3.5 feet; (3) light gray massive limestone, 1.5 to 3.5 feet. Thickness 10 to 11 feet. Overlies Legion shale member and underlies Salem Point shale member. Condra states that the Kansas Geol. Survey correlates Legion shale and underlying Sallyards limestone with Roca shale formation. Age is considered Permian (lower part of Big Blue).
In 1936 (Kansas Geol. Survey Bull., no. 22) R.C. Moore transferred Roca shale to Permian. This change in Permian-Pennsylvanian boundary has not been considered [ca. 1938] by the USGS for its publications.

(Paleozoic Era; Permian System by H.G. O'Connor, D.E. Zeller, C.K. Bayne, J.M Jewett, and Ada Swineford, p. 46.) Burr Limestone Member of Grenola Limestone of Council Grove Group. Fossiliferous gray limestone and gray to olive-gray shale. In Chase County, Kansas, the middle limestone beds are very fine-grained and platy. Ostracodes are abundant in some of the limestones. Mollusks and other fossils are abundant locally in the lower beds. Thickness 1 to 15 feet. Age is Early Permian; Gearyan Provincial Stage (of H.G. O'Connor, 1963, AAPG Bull., v. 47, p. 1873-1877).
