View of Siccar Point looking from the south-west, Berwickshire


Siccar Point viewed from the south-west. Berwickshire. 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.

Basal breccia or conglomerate of Upper Old Red Sandstone dipping at a low angle to left (north), resting on vertical shaly siltstone and thin greywacke of Silurian (Llandovery) age. The breccia consists of angular fragments of greywacke in a red, sandy matrix.

Siccar Point has outstanding historical associations, stemming from a visit paid by James Hutton in 1788, accompanied by Sir James Hall and Professor John Playfair.
