LIST OF APPENDICES
Appendix 1 Literature compiled for the present study of channel-body geometry (the
dataset). The papers listed contain relatively complete information about channel-body
width, thickness and width/thickness, or provide important supporting information for the
documented rock units.
Appendix 2 Thirteen Excel® spreadsheets and graphs for each category of channel
body and valley fill, numbered according to the figure numbers in the paper. The raw
data sets are listed and numbered in columns A to F of each spreadsheet page. The actual
plotted data (points, lines, boxes, polygons, envelopes) for the dataset and for W/T lines
are provided in columns to the right. The graph below is a working graph in color, from
which individual datasets can be identified according to the numbers in column A. The
accompanying file (JSR_Gibling_Plotting_Graphs) provides information about how to
create and modify the graphs using Excel®.
Appendix 3 Photos of braided and low-sinuosity river deposits in the rock record.
A) Siwalik Group (Pleistocene), north of Chandigarh, India. Pale sheet sandstones ~5-10
m thick (arrowed) alternate with sheets of red floodplain fines. Although originally
deposited on a megafan south of the Himalayan thrust front, the foreland-basin strata
have been exhumed by later thrusting.
B) Castlegate Sandstone (Cretaceous) near Price, Utah. The cliff is ~100 m high at the
right-hand side, and comprises stacked sheet sandstones and thin fine selvages, with
cryptic sequence boundaries (Miall and Arush 2001).
C) Hawkesbury Sandstone (Triassic), south of Sydney, NSW, Australia. Braided-fluvial
sandstone sheets contain large barforms (arrowed) and a mud-filled channel body 12 m
thick. Field party (circled) for scale.
D) Cadomin Formation (Cretaceous), Adanac Mine, Alberta, Canada. A thin, extensive
sheet of conglomerate and sandstone ~12 m thick rests on coal (within scree slope just
above small lake in foreground). Cordilleran thrust sheets in the background.
Appendix 4 Photo of meandering river deposits of the Rangal Coal Measures
(Permian), Queensland, Australia. A channel body 8 m thick with prominent lateral
accretion surfaces (point bar deposits) rests on and is overlain by coal. A braided sheetsandstone lies just below the cliff top.
Appendix 5 Photo of megafan systems of the Lourinha Formation (Jurassic), Porto
Nuovo, Portugal in cliff 15 m high. Thin, lenticular channel sandstones (arrowed) up to 3
m thick, variously seen in cross- and longitudinal sections, lie within mudstones. More
extensive sandstone bodies are longitudinal sections through channel bodies and
crevasse-splay sandstones.
Appendix 6 Photo of delta distributary channel deposits of the Cretaceous Ericson
Formation (Rusty Member), near Rock Springs, Wyoming. The lenticular channel bodies
(arrowed) are ~ 5 m thick and are encased in mudstone with coaly intervals. An incised
valley fill of sandstone forms the cliff top.
Appendix 7 Photos of fixed river deposits.
A) Anastomosing river deposits of the St. Mary’s River Formation, Cretaceous, Alberta,
Canada. Topmost ribbon-channel body is 4 m thick and mainly accreted vertically, with a
low levee and splays that thin into the floodplain deposits. The margins of two other
channel bodies are visible low in the cliff.
B) Castissent Sandstone (Paleogene), Tremp-Graus Basin, Spain. Ribbon sandstone (A1
body of Marzo et al. 1988) has steep margins and is 10 m thick (arrowed), and is
amalgamated with the overlying braided-fluvial sheet sandstone. The ribbon may
represent a pre-existing drainage system filled by the encroaching braided river. Stacked
braided- and meandering-fluvial sheets overlie these deposits, and form part of a complex
valley fill.
Appendix 8 Photo of channel bodies up to 2 m thick composed of angular and poorly
sorted limestone gravel, cut into eolian sands, Corrie Sandstone (Permian), Isle of Arran,
Scotland. Channel bases are abrupt and erosive, as at base of photo.
Appendix 9 Photo of estuarine valley fill of the Paddy Formation cut into Cadotte
Formation shoreface sandstones, Peace River, Alberta, Canada. Both units are Cretaceous
in age. The basal erosion surface (arrowed) is marked by the Glossifungites ichnofacies,
indicating that the substrate was only partially consolidated at the time of lowstand
incision.
