| Carving the Stone The stone for the monument, a Carboniferous quartz arenite, would have been obtained locally and was ideal for carving. |
| The sampled sandstones are light grey, very fine-grained, weakly cemented arenite, mostly dominated by quartz grains. |
| One is to call the sandstone an arenite, and the other is to call it a wacke. |
| The magaripples occur on the upper bedding plane of a 35-cm thick, medium to coarse-grained quartz arenite. |
