文摘
- •
Upper Devonian Foreknobs Formation exhibits conglomeratic incised valley fills.
- •
Black shale and conglomeratic HCS storm-event beds signal sea-level drawdown.
- •
Distal lowstand wedges are genetically related to proximal incised valley fills.
- •
Glacial ice-sheet areal extent can be calculated from inferred sea-level falls.
- •
Magnitude of sea-level fluctuations is moderate and can be related to glacioeustasy.
