The succession is divided into two units. The lower unit is 30–40 m thick and consists of medium- to coarse-grained sandstones topped by silty, fine-grained sandstones. The upper unit is up to 155 m thick and differs from the clean sandstones that typify the for- Lower–middle shoreface Offshore – lower shoreface Offshore Trace fossils Bioturbation weak Bioturbation moderate Bioturbation strong Diplocraterion Monocraterion Ophiomorpha Planolites Curvolithos Helminthopsis?

The section was compiled from five part-sections located in a north–south direction along Gulelv (Figs 2, 6). Modified from Larsen et al.

The lower sandstone unit and the Spath Plateau Member are described and interpreted separately below; the latter member is defined formally as a new member of the Pelion Formation. 57
