Description

CRAIG MORE Craig More lies a mile east of Comrie in western Perthshire. It contains exposures of a large body of igneous rock called the Comrie Pluton. The Comrie pluton is a fine example of a zoned pluton and is notable among the Scottish Newer Granites for the high proportion of dioritic rock-types. In the vicinity of Craig More coarse-grained hornblende diorite is seen to intrude and metamorphose the Aberfoyle Slates of Dalradian age. The metamorphic aureole has been the subject of early pioneering studies into progressive contact metamorphism of pelitic metasediments and is of international renown.
