| Description: | Pettycur shore, Kinghorn, Fifeshire. Columnar basalt lava, the columns dying out above. The central portion of a lava flow is more regularly jointed than the top or bottom because it cools more slowly and at a more constant rate. As heat is lost mainly from the top and bottom of the flow, the principal joints form at right-angles to the top of the flow. The photo shows vertically-jointed polygons of basalt forming the centre of a flow. The rubbly top of the flow is seen at the top of the cliff, left. Lava flow forms part of Kinghorn Volcanic Formation (Strathclyde Group). Village of Pettycur in background. |
