Columnar sections of the Ugab Subgroup in the Vrede domes. Sections 1–12 are ordered anticlockwise around the domes (see inset map and Fig. 10 for locations), minimizing the separation of adjacent sections. There is a major facies change from coarse-grained alluvial clastics in the north (column 12) to coastal marine carbonate in the south (columns 3–5), with northward backstepping of clastic tongues over time. Blue shade indicates predominant carbonate, pink shade predominant siliciclastic. Vertical datum (0 m) is a mappable flooding surface beneath the upper dolomite ribbonite unit and is used as a paleo-horizon (Figs. 15–16) for reconstructing the paleotopography of the sub-Chuos glacial erosion surface (Fig. 11B). Field number for each section is shown beneath the column number.

—Columnar sections at southeast end of Nuka Ridge. Sections originally reported (Tailleur and Sable, 1963) are shown in column I; section A was designated type section for Nuka Formation. Sections measured or reexamined in 1971 are shown in column II; as plotted on Figure 2, line of section “A” coincides with line for lower part of section A but is north of that line for upper part; section T. 71.28 crosses north flank of Nuka Ridge about 3 mi northwest. Tentative stratigraphic and structural interpretations—wavy lines for unconformity, arrow for flat thrust, and queried arrow for uncertain discordance—are shown in column III, based on foraminiferal zonation by Mamet and macrofaunal determination by Dutro. New reference section for Nuka Formation is indicated arkosic unit near middle of section “A”.

Columnar sections along the surveyed routes and interpretation of the sedimentary environment. The rose diagrams of paleocurrents were based on current ripples. The numbers in squares to the left of the columnar sections are equivalent to the outcrop numbers (Online Supplemental File Fig. S1). Ammonoid zonations are from Bando and Ehiro (1982), Ehiro et al. (2016, 2019), Ehiro (2022a, 2022b) and Shigeta (2022). Key: Eo = Eodanubites.

Columnar sections of the complex outcrop Bardo IV, near a road to the Opolnica village, SW Poland, logged in 2017 (see Figs. 1B, 3, 4A, and 4B), ordered in the succession according to field logging, i.e., in inverted order in light of biostratigraphic datings. The variation in the lamination and fabrics of layers and styles of tectonic deformation are shown, as well as soft-sediment deformation structures, in the lower conglomeratic part of section IVb (photo A). All sections are in the same vertical scale. Three examples of etched chert slabs (in HF), presented in the lower right corner, show an erosional contact of radiolarite with mudstone (sample IVc/1; B), recrystallized radiolarian(?) test (RK IVc-3; C), and a fragment of alleged graptoloid rhabdosome (RK IVc-3; D), respectively. HBS—Hangenberg Black Shale.

Late Tonian(?)−early Cryogenian columnar sections in Toekoms sub-basin (modified after Hoffman et al., 2017). Section locations shown on inset map (lower right) and Figure 4. Unit 1 (blue number) is provisionally pre-Sturtian and units 2−5 belong to Chuos Formation, deposited subaqueously in a Sturtian subglacial lake or fjord. Unit 1 and proximal unit 3 are dominated by basement-derived conglomerate. Units 2 and 5 are dominated by resedimented diamictite. Unit 4 and distal units 2 and 3 are dominated by argillite with ice-rafted lonestones and turbidites of silt- and sandstone. Wave and traction-current bedforms are absent in units 2−5. Lateral persistence of thin unit 5 diamictite implies a non-erosive top of Chuos Formation. Slip on Toekoms growth fault ceased before deposition of middle Cryogenian limestone turbidites of Berg Aukas and/or Okonguarri formations (green). Secular shift in maximum accumulation from proximal (units 1−2) to distal (unit 4) wrt Toekoms growth fault is characteristic of Mesozoic rift basins formed above listric growth faults on the North Atlantic continental margins (e.g., Petrie et al., 1989; Driscoll et al., 1995).

Cryogenian columnar sections from the autochthonous panel of Bethanis and Soutput sub-basins (Hoffman et al., 2021). See Figure 4 for section locations. Note thickening of Chuos (Ac), Berg Aukas (Aa), Okonguarri (Ao), Narachaams (An) and lower Ghaub (Tg) formations toward Soutput growth fault, indicating fault displacement from late Sturtian through early Marinoan time. Displacement apparently ceased before deposition of upper Ghaub Formation massive carbonate diamictite. Not shown is the early Ediacaran Karibib Formation (328 m in section 1-19, Figure 3b) consisting of post-rift foreslope dolomite turbidites and debrites.
