摘要:
The Late Devonian Worange Point Formation is a cyclical, fluvial deposit >900 m thick. South of Eden, part of this succession (220 m) contains cycles composed of seven facies: (A) conglomerates on an irregular erosion surface; (B) coarse to medium grained sandstone, massive or with large‐scale cross‐stratification; (C) medium to fine grained sandstone with small‐scale cross‐stratification; (D) thinly interbedded fine grained ripple laminated sandstone and mudstone; (E) red mudrocks; (F) thin medium to fine grained sandstone in Facies E; and (G) green, fine grained sandstone. These facies are interpreted as the deposits of meandering stream channels (A, B, and C) with levee deposits (D), flood‐plain deposits (E) containing crevasse‐splay deposits (F), and abandoned channel fills (G). Together they make up fining‐upwards fluvial cycles averaging 10 m in thickness.
