Detailed studies of the relationship between structure and metamorphism in the southern Scottish Highlands and new Rb-Sr isotope data for the Rough Craig Granite have resulted in a revision of the tectonothemal history of the Dalradian. Two main events are recognized. The first (Dl), probably at c. 590 Ma, produced a regiondy inverted stratigraphic succession on the underlib of the Tay Nappe. The second event, possibly between 520 and 470 Ma, encompassed regional D2 and D3 deformation phases and was synchronous with peak Barrovian metamorphic conditions.
