| Caption: | Siccar Point, northward view. Berwickshire. |
| Description: | Dark red sandstones and breccias of the Upper Old Red Sandstone age occupy the right half of the photograph, dipping northwards at a low angle. On the left and cutting across the foreground are faintly purplish greywackes and siltstones of Silurian (Llandovery) age dipping at about 60 degrees to south-south-east. The unconformity between the two formations is clearly displayed. The concept of structural succession, the Silurian rocks having clearly evolved through a longer and more complex history than the Old Red Sandstone and the similarities between ancient and modern sedimentary processes are expressed in a self-evident way and one clearly identified by James Hutton during his visit in 1778. Unconformity between Upper Old Red Sandstone and the underlying Silurian (Llandovery) age rocks. Hutton's classic world-famous unconformity. He was the first geologist to grasp the true significance of such a structure. |
