| The upper surfaces of wacke beds are less well characterized by sedimentary structures. |
| These internal structures are arranged within wacke beds in a regular sequence. |
| The most typical external structures of wacke beds are sole markings, which occur on their undersurfaces. |
| Greywacke is an old term still sometimes used for a particular type of wacke especially in grey-coloured turbidite sequences. |
| The hole continues through a sedimentary sequence comprised of fine to medium grained wacke and local fine siltstone and argillite sections. |
| More distal carpets of wacke sand can extend for thousands of square kilometres across oceanic abyssal plains. |
