Summary:The granite belongs to a suite of intrusions within Moine psammites adjacent to the base of the east Sutherland migmatite complex. The age of 405 +- 11 m.y. obtained by U-Pb determinations on zircon by Pidgeon & Aftalion is judged to be an untenable intrusion age on geological evidence. It is suggested that the granite suite originated at depth and was channelled into the still active Caledonian ductile Naver thrust at least 435 m.y. ago. [C.H.D.]
