Redescribed	Williston basin

Summary:
Uses "facies" as designation for formational unit in Madison Group in north-central ND and southeastern Saskatchewan, in the Williston basin, to emphasize that its boundaries transgress time lines. Is represented by dense, argillaceous, often cherty, limestones characteristic of carbonate deposition in deep water, off the marine shelf. Although these beds are generally quite dense, porosity has developed locally in certain areas as will be seen by designations on type logs for Canadian and Bottineau, ND, areas. Base of Lodgepole facies is locally unconformable contact of lowest carbonate with black shale of underlying Bakken formation. Upper part interfingers with partly equivalent and partly overlying Mission Canyon facies. Includes an unnamed electric and radioactivity-log [shale] unit at base and, locally, equivalents of Tilston member which is an overlying electric- and radioactivity-log unit. Mississippian in age.

Biostratigraphic dating	Montana folded belt province Williston basin

Summary:
Shows distribution on map of coral zones in four stratigraphic sections, in Gallatin and Madison Cos, MT in Montana folded belt province, and in Blaine and Wibaux Cos, Williston basin. Coral zones in Lodgepole are (ascending): Zone C2 is arbitrarily placed at contact of Lodgepole with overlying Mission Canyon limestone in 4 sections. Lists characteristic coral genera in the zones. Zone A and part of Zone B may be represented in Little Chief Canyon member of Lodgepole of central MT and Bakken formation of Williston basin. Zone C1 is readily identified in cores drilled in Williston basin (section 8). Coral faunas do not provide a satisfactory basis for detailed correlation with type Mississippian of Midcontinent region, because their sensitivity to depositional conditions appears to have given rise to different assemblages and distribution patterns in rocks believed to be nearly contemporaneous. Preliminary studies by Dutro, Jr., of brachiopods associated with coral assemblages suggests tentative correlations with type Mississippian: Zone A appears to be entirely of Kinderhook age. Beds equivalent to part of Kinderhook may be present in Zone B, and they possibly extend into C1. Osage equivalents are found in C1. These correlations are confirmed, in general, by distribution patterns of coral genera common to Madison and type Mississippian sequences.

Overview Biostratigraphic dating	Williston basin

Summary:
Corals from three wells in Wibaux, Dawson, and Roosevelt Cos, respectively, northeastern MT, Williston basin, are divided into three groups for facies analysis: nondissepimented solitary corals, dissepimented solitary corals, and colonial corals. Lateral changes in abundance, diversification, and vertical limits of coral fauna seem to be directly related to changes in lithic facies. A northward impoverishment of fauna of Lodgepole [of Madison group] seems to be correlated with increase in clay content and decrease in grain size of limestone toward center of a basin characterized by poor circulation of sea water. Dissepimented corals are much more abundant in Lodgepole than in overlying Mission Canyon limestone; Mission Canyon fauna consists predominantly of solitary forms suggesting better aerated conditions in Mission Canyon time. Corals hold little promise as horizon markers because of strong facies control and long stratigraphic range of common genera. They offer greater potential for regional correlation because of wide distribution of distinctive associations of genera and species in rocks of Early Mississippian age. Describes 24 species distributed among 18 genera, collected from (ascending) Lodgepole and Mission Canyon limestones and Charles formation. Shows frequency distributions and stratigraphic ranges of coral types or coral genera. Early Mississippian in age.

Summary:
A section 555 ft thick measured in Little Chief Canyon, NE1/4 NW1/4 sec 30, T26N, R25E, Blaine Co, MT, Williston basin designated type section of Lodgepole. Divided into Paine Member (base), a medium- to olive-gray, medium- to fine-grained, crinoidal, silty to argillaceous limestone; and Woodhurst Member (top), a fine- to coarse-grained, light-gray to brown crinoidal limestone. A thin black shale beneath Paine, formerly called Little Chief Canyon Member of Lodgepole reassigned to underlying Bakken Formation. Little Chief Canyon abandoned. Term "shale" removed from formal name Paine because "shale" doesn't apply to rocks identified as limestone. Term "limestone" removed from Woodhurst because limestone part of formation name. Two other sections measured where Lodgepole overlies Three Forks Formation. Black shale beneath Paine in two sections retained as Cottonwood Canyon Member of Lodgepole. Underlies Mission Canyon Limestone at all three sections. Extends into Sweetgrass arch and Central Montana uplift. Fossil (brachiopods, corals, fusulinids) lists. Correlation diagram. Cottonwood Canyon and Paine are Kinderhookian, Woodhurst is Osagean, or all of Early Mississippian age.
