Fig. 11. Middle and Late Triassic facies. (A) Proximal cross-stratified and low angle stratified fluvial sandstones with common mud-clast lags. The
composition of the mud-clast lags commonly differs from floodplain fines in being finer grained and well laminated and may represent erosion of in-channel
slack water mud drapes, UK 22/29-5RE. Truncation surfaces defining low angle cross bedding are highlighted by arrows. (B) Distal, mud-prone and
heterolithic fluvial deposits representing muddy accretionary bar deposits with vegetated and burrowed upper bar surfaces, UK 29/10-3. Such facies are
more common in the south of the basin and in the stratigraphic transition into the regional Skagerrak Formation shale members. Both examples have
carbonate cemented, calcrete clast basal lags. Cores 1 m long.
