| Lithological Description: |
An asymmetrically zoned intrusive body with an inner zone of medium- to coarse-grained porphyritic granite and an outer zone of foliated granodiorite. Both zones are intruded by thin aplite veins. A series of microdiorite dykes are linked genetically to the intrusion of the pluton. |
| Definition of Lower Boundary: |
Intrusive margin of the pluton against surrounding contact metamorphosed rock. |
| Definition of Upper Boundary: |
Not applicable. |
| Thickness: |
Modelling of gravity data indicates that it extends to a depth of 9km. (Lintern, B C and Floyd, J D. 2000; Bott and Masson Smith, 1960). |
| Geographical Limits: |
The pluton is exposed in south-west Scotland. It extends from Auchencairn Bay [NX 83 52] in the south-west to Mabie Forest [NX 94 71] in the north-east. |
