The carboniferous is composed of channelized fine sandstones in silty floodplain. Some levels are very rich in organic matter and some plants can be found such as ferns. The Triassic is composed of channelized quartzite with beautiful lateral accretions. The contact forms a nice angular discontinuity. Picture by Anne-Sabine Grosjean and Baptiste Suchéras-Marx
