Site no.: B15
Site name: Red Craig
Grid reference:
Locality: Glen Doll
GCR Status: Confirmed
GCR No.: 2499
Type: Natural exposures
Description: The site lies at the eastern margin of the Glen Doll Dioritic Pluton, a member of the South Grampian Subsuite of late Caledonian intrusions. The area exhibits a range of igneous rock types, with transitions from quartz-diorite through quartz- monzodiorite to granite. The GCR volume 'Caledonian Igneous Rocks of Great Britain' (Stephenson et al., 1999) contains a full description of the site.
Justification: Long recognized as providing well-exposed and easily- accessible evidence of the interaction between component magmas of a basic to intermediate intrusion. The igneous rocks contain fragments of their country rocks (xenoliths) and provide excellent examples of the interaction between the inetrmediate part of the pluton and the host Dalradian metasedimentary rocks.
