Description: Kincraig neck, 2 km. west of Elie, Fifeshire. A columnar intrusion. The basaltic neck intrusion is in the form of an inverted cone, and shows striking columnar jointing. The feeder channels at the centre are marked by basaltic intrusions and masses of basaltic breccia. The photograph shows the largest such intrusion almost 150 metres across at the base and floored by tuffs showing collapsed bedding. More than one hundred volcanic necks have been located in east Fife. They are approximately vertical pipe-like bodies ranging in diameter from less than 100 metres to 1.5 km. Consisting mainly of pyroclastic rocks, they pierce the Carboniferous sediments and mark the sites of former subterranean channels through which volcanic eruptive material passed.
