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.
