| The hole continues through a sedimentary sequence comprised of fine to medium grained wacke and local fine siltstone and argillite sections. |
| The material of the rock here is wacke, in which there are many flints. |
| The hole anchored in bedrock at 13.0 metres and cut through wacke with local hematite and epitode alterations to 274.4 metres. |
| The three major arenite sandstone families are separately described below, but the varieties of wacke can be conveniently considered together as a single group. |
| More distal carpets of wacke sand can extend for thousands of square kilometres across oceanic abyssal plains. |
| The Long Creek Formation consists of laminated quartzose argillite and sandstone interbedded with altered basaltic rocks and minor quartz-rich lithic wacke. |
