| Lithology description: footprint: "small coarse-grained limestone block" "a meter thick, white or grey, fine-grained silty sandstones, with gypsum and thin organic laminae. The organic laminae frequently highlight distinct erosive-based sets with cross-stratification and, sometimes, parallel stratification. These sediments are interbedded with up to three layers of trough cross-stratified, moderately sorted, medium to coarse feldspathic sandstones. In general, these coarser grained layers are less than 0.80 m thick, wedging out laterally into the fine-grained deposits. Channel-shaped beds of fining upward coarse to medium-grained sandstone with scattered pebbles occasionally occur. Cross stratification and the geometry of the channel-shape beds indicates a general W to SW direction of the palaeocurrents. This mostly siliciclastic interval passes upwards to mudstone-marl layers with carbonate nodules. | |
| Environment: | coarse channel fill |
| Geology comments: "The coarser grained units, which texturally resemble the tridactyl footprint sediment cast, probably represent deposition in distributary channels within the coastal plain. The thicker and coarser sandstone bed may be attributed to a larger channel" | |
