Summary of site:
The age of this small, vertical, cylindrical plug of dolerite enclosed in Newry Granodiorite is disputed. It is seamed with granitic veins that have been attributed by some experts to the Newry granodiorite, which would make it Devonian in age, around 400 million years old. A reinterpretation gives an alternative explanation and a Tertiary age of around 58 million years.
