Summary:

Pg. 99, 100, 103. Critizer limestone member of Swope formation of Bronson group. Critizer limestone is second limestone lentil from base of Swope formation. It is brown, earthy, massive, and varies from an oolite to a dense crystalline limestone. A large BELLEROPHON abundant. Thickness locally 15 feet. To south pinches out near Linn-Bourbon County line. Age is Late Pennsylvanian (Missouri age). [On Moore's chart (p. 97) Critizier is classed as a member of Swope limestone (formation) of Bronson group.]
Type locality: south of Critizer [Critzer], in sec. 17, T. 22 S., R. 23 E., Linn Co., KS. It is believed to extend well into MO.

Summary:

Summary:

Pg. 74-75, 80. Critzer is correct spelling. Jewett classed it a member of Swope formation, and, according to F.C. Greene, N.D. Newell, and me, base on 1934 field work, assigned it to erroneous position above Schubert Creek limestone. It is believed by Greene and me to be = "Fragmental limestone," of Iowa geologists. For present recognition of "Critzer" as a named member of Bourbon formation is withheld, although it may prove to be useful name for a marker bed near top of Bourbon formation from Linn County, Kansas, northward.

Summary:

(Paleozoic Era; Pennsylvanian System by J.M Jewett, H.G. O'Connor, and D.E. Zeller, p. 28.) Critzer Limestone Member, lowermost member (of 2) of Hertha Limestone of Bronson subgroup [informal] of Kansas City Group. Consists of a massive, brownish-gray, granular, partly algal limestone and a thin, wavy-bedded, gray limestone. In a part of the outcrop area this member is the most conspicuous part of the Hertha Limestone, commonly forming a rimrock along the Hertha escarpment. Much of the rock weathers deep brown. Bellerophontid gastropods are characteristic of the massive facies; brachiopods and corals are plentiful locally in the thin-bedded facies. Thickness 0 to about 11 feet. Age is Late Pennsylvanian (Missourian).
["Subgroup" not recognized as a formal stratigraphic rank term (CSN, 1933; ACSN, 1961, 1970; NACSN, 1983, 2005). Considered informal and should not be capitalized.]

Thompson, T.L., 2001, Lexicon of stratigraphic nomenclature in Missouri: Missouri Division of Geology and Land Survey Report of Investigations, no. 73, 371 p.


Summary:

Thompson (1995, p. 112) stated "The Critzer Limestone Member...is a nodular, locally fossiliferous limestone which is absent in some areas. The limestone is commonly argillaceous or silty and appears to grade laterally into sandstone or siltstone. Where the limestone is absent, its stratigraphic position is occupied by maroon clay. The thickness of the Critzer is generally less than 1 foot." Recent correlations (Heckel and Watney, in press [2002]) have placed the Critzer at the top of the Pleasanton Group. The Critzer Limestone Member overlies the shales of the Pleasanton Group, and is overlain by the Mound City Limestone Member of the Hertha Formation.
[Heckel and Watney (2002, p. 12, 13, fig. 8) placed Guthrie Mountain shale member (new) at top of Pleasanton Group; a distinct gray shale unit that was previously included in the overlying Mound City (restricted). Critzer now lies below the Guthrie Mountain, and is revised to include the "Bourbon flags" as its southeastern facies.]
