... is within the lowest Virgilian (Stephanian) Douglas Group ( Figure 2 ). The underlying Lansing Group and overlying lower Shawnee Group both contain thick, laterally extensive limestones and typical Kansas-type cyclothems ( Heckel, 1977 ). In contrast, the Douglas Group in Kansas lacks the thick limestones...

Schematic cross section of upper Missourian to lower Virgilian stratal succession along outcrop belt (see Figs. 1, 4), supplemented with shallow subsurface data. The cross section is slightly oblique to depositional dip. Geometric relationships have been somewhat altered to show three-dimensional relationships in a single cross-section. Small-scale variations in thickness have been smoothed, and thicknesses of thin units (such as black shales and coals) have been exaggerated for readability. Sequence boundaries (red) are shown as solid lines only in areas where they can be confidently correlated. Basinward extent of SB 4 is based on subsurface extension of the large incised valley basinward; no interfluve SB has been recognized for this sequence. Construction of cross section is based on observations from our previous studies (Joeckel 1989, 1994, 1995a; Cunningham and Franseen, 1992; Feldman et al. 1993b; Feldman et al. 1995; Feldman et al. 1997; Lanier et al. 1993; Archer et al. 1994; Archer and Feldman 1995; Heckel and Watney 2002), our new data introduced in this paper, and supplemented with data from Bowsher and Jewett (1943), Ball (1964), Troell (1969), Kansas City Power and Light (1975), and Goebel et al. (1989). Significantly modified from Archer and Feldman (1995).

Wide areas with oblique lining represent outcrop of mound complexes; narrow lines represent nonmound facies; all traces are straightened and simplified. Lines 1-3 mark alignments of mound terminations and other features in Missourian rocks (after Heckel and Cocke, 1969).

—Classification of lower and middle Virgilian rocks in northern Mid-Continent region. Column at extreme left shows agreed inter-state classification which is subject to modifications imposed by lateral variations of deposits. Other columns indicate previous usage in several states. Some deviations shown, especially in Douglas group, will persist. In northern Oklahoma there are unsettled questions of classification and nomenclature.

—Ideal Upper Pennsylvanian megacyclothem showing complete development of all members, as typified by Oread megacyclothem in Shawnee Group of lower Virgilian Stage (after Moore, 1936, p. 26-35; 1949, p. 78-79, 144-145; personal observations). (O) marks shale members that are more like outside shale than black shale member. Megacyclothems of Missourian Stage lack lower, fifth, and commonly super limestone members. Inferred sea-level curves reflect two hypotheses: (1) simple short-term oscillation differentiating shale members from limestone members (dotted line, combining Moore, 1936, p. 30-35, and Wagner, 1966, p. 567); and (2) basically long-term oscillation with black shale member differentiated from other shale members on account of major depth-zone difference (solid line, after Evans, 1967, Fig. 6; Troell, 1969, p. 25, specifically for Oread megacyclothem; Schenk, 1967, p. 1379-1380, for Altamont megacyclothem). Inasmuch as most Missourian megacyclothems consist mainly of middle limestoneblack shale-upper limestone member sequence, hypothesis 2 for them becomes simple long-term oscillation of sea level.

Pennsylvanian-Permian stratigraphy of the western (San Andres Mountains), eastern (Sacramento Mountains), and southern (Franklin Mountains) Orogrande basin. Phylloid algal mounds are present in the Virgilian Panther Seep Formation of the San Andres Mountains (this study), the Virgilian-lower Wolfcampian section of the Sacramento Mountains (references in text), and the Desmoinesian section of both ranges (Algeo et al. 1991). Middle-late Virgilian age for the western Orogrande mounds is based on fusulinid identifications by G. Wahlman and G. Wilde (data in Soreghan and Giles 1999a). Stratiform gypsum (carat pattern) is present in the uppermost Pennsylvanian section in the Franklin Mountains (references in text). Stratigraphy after Kottlowski et al. (1956), Otte (1959), and Harbour (1972).
