This excursion will look at the Silurian rocks at Milldown Point and their relation to the adjacent Lower Devonian volcanic rocks: porphyrite and agglomerate. The Silurian rocks which crop out around Coldingham differ in character from those seen nearby and the main object of this excursion is to examine these rocks on the shore.

We will view the volcanic vent at St. Abbs Haven and then consider the nature of the Coldingham Beds and Linkim Beds at Milldown Point, their similarities or otherwise, and their relation to the volcanics. We will also visit Callercove Point to view the volcanic vent downfaulted against the Linkim Beds.
