FIG. 26 in Allostratigraphy And Biostratigraphy Of The Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

FIG. 26. Summary representation, to scale, of stratal geometry viewed in strike (NW-SE) and three dip (NE- SW) sections spanning the study area. Lower Coniacian strata fill a saucer-shaped depocenter that thins to both NW and SE, whereas Middle Coniacian strata are thickest in the south but are erosionally truncated toward the NW. Upper Coniacian strata fill a depocenter in the NW but are truncated toward the SE, and are largely absent over most of southern Alberta and northern Montana. Sections summarized from figures 4, 8, 11, and 13.

FIG. 25 in Allostratigraphy And Biostratigraphy Of The Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

FIG. 25. Comparison of the organic carbon isotope stratigraphy at Cutpick Creek with the carbonate carbon isotope reference curve for the English Chalk succession (after Jarvis et al., 2006, recalibrated to GTS2012 after Laurin et al., 2015). The Cutpick section, and corresponding carbon-isotope curve, has been "expanded" to show the location of hiatuses determined on the basis of regional subsurface correlation (i.e., fig. 4). Biostratigraphic collections made in all the Coniacian sections included in this study (fig. 24), allow three tiepoints to the UK Chalk to be established at the lowest occurrence (LO) of Cremnoceramus crassus crassus, and the lowest occurrence of Volviceramus. The base of the Santonian is defined at the co-appearance level of Clioscaphites saxitonianus and Sphenoceramus ex gr. pachti, which corresponds to surface SS0 of this study. The lowest occurrence of C . crassus, Volviceramus and Scaphites (S .) depressus allows tentative correlation to the Portland core, which does not extend as high as the Coniacian–Santonian boundary (Joo and Sageman, 2014). The highest local occurrence of Inoceramus gibbosus, which is widely distributed in allomembers CA3 and CA4 in the western Alberta foredeep, is marked by the lag-strewn erosion surface CS4, suggestive of significant sea-level fall and subsequent transgression. The absence of the I . ex gr. gibbosus interval in most sections of topmost lower Coniacian strata in other parts of the world suggests that a significant hiatus exists at the base of the overlying Volviceramus Zone.

FIG. 15. A in Allostratigraphy And Biostratigraphy Of The Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

FIG. 15. A. Overview of surface CS1 exposed at river level at the mouth of Oldfort Creek (fig. 10). At right, a coarse-grained wave ripple composed of granules and small pebbles of chert and quartz rests sharply on regional erosion surface CS1. Traced laterally over only 3 m, the coarse lag pinches out and surface CS1 is manifest simply as a sharp mud-on-mud contact; scale bar = 20 cm. B. Detail of the coarse-grained wave ripple.

FIG. 20. A in Allostratigraphy And Biostratigraphy Of The Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

FIG. 20. A. The upper part of the Marshybank Member at the Bighorn Dam section (fig. 7). Surface CS23, which is mantled with chert and siderite pebbles, marks a maximum regressive surface and is overlain by four subtle upward-coarsening successions culminating in surface SS0. B. Upper part of the Marshybank Member exposed on the Bighorn River (fig. 7) showing bioturbated sandy siltstone grading up into weakly stratified silty sandstone, the top of which is marked by surface CS23.

FIG. 22 in Allostratigraphy And Biostratigraphy Of The Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

FIG. 22. Offshore facies typical of the Muskiki Member. A. Weakly bioturbated (BI 0-1) cm-scale beds of very fine-grained sandstone interstratified with mudstone forming an upward-coarsening succession culminating at flooding surface CS4. The rusty-weathering colour is typical of this facies and is due to abundant disseminated pyrite. Overlying rock comprises weakly bioturbated mudstone with mm-scale siltstone interbeds. Example: "Brown Creek" section (fig. 6, 11–19 m). B. Stratified mudstone (BI 1-2) with mm-scale coarse siltstone interbeds and abundant, dispersed siderite nodules; scale bar = 20 cm. Example: Oldfort Creek (fig. 10, 42–46 m). C. Heavily bioturbated (BI 4-5) sandy siltstone with dispersed siderite nodules. Example: Oldfort Creek (fig. 10, 49–52 m).
