Lithology and environment
| Primary lithology: | massive,fine,brown mudstone |
| Includes fossils? | Y |
| Lithology description: "The first lithofacies is a massive, dark-brown mudrock. There are no pedogenic features or sedimentary structures. These beds can be tens of meters thick. Bones as well as other non-bioclasts are found “floating” in the fine-grained matrix." | |
| Environment: | lacustrine indet. |
| Geology comments: "We interpret the first lithofacies to be both hyperconcentrated-flow- and lacustrine deposits." | |
