IN the neighbourhood of Haddo House, between Methlick and Ellon, some 20 miles north of Aberdeen, there is a considerable body of gabbro that has been named the Haddo Mass. This intrusion is later than the general metamorphism of the Dalradian country-rocks and, from its resemblance to certain dated intrusions, earlier than the local Middle Old Red Sandstone. It belongs, therefore, to the Younger Gabbro portion of the Post-Movement Phase in the igneous history of North-East Scotland.
