Fig. 6. Lower Triassic facies. (A) Terminal splay deposits comprising interbedded shales and ripple laminated to plane bedded sandstones, UK 29/8-3. (B)
Weakly confined to unconfined fluvial deposits composed of current ripple laminated, very fine-grained to fine-grained sandstones with abundant mud
clast lags, UK 21/18-5. (C) Close-up image of highlighted area in (B) illustrating mud clast-floored scour and steeply climbing current ripple lamination. (D)
Plane bedded and cross-bedded (arrowed), fine- to medium-grained fluvial sandstones with mud clast lags, UK 21/19-6. Cores 1 m long.
