| The metaconglomerates comprise monocrystalline or polycrystalline angular or subrounded clasts of quartz embedded in an arenaceous matrix. |
| The limestone clasts contain rudist fragments and larger foraminifera that indicate erosion from the Campur Formation. |
| Furthermore, it is not always clear whether fossils from a given locality are from in situ rocks or from spoil or clasts in glacial drift. |
| Interstices are filled with poorly sorted pebble-sized clasts and the matrix content is rather low. |
| The second unit found immediately above beach level consists of deformed laminated sand and mud containing clasts up to 10 cm across. |
| The sedimentary clasts also contain abundant opaque minerals, chiefly magnetite. |
