Abstract
New uranium-lead isotope data from monazites yield an emplacement age of 470+ or -1 Ma for the 'S'-type Aberdeen granite. Emplacement of this intrusion was late-tectonic with respect to the Grampian (early Caledonian) orogeny, and followed closely on the upper amphibolite facies metamorphic climax in the Dalradian country rocks. We advocate extensive contemporaneous melting of rocks at shallow depths below the level of emplacement (then 17-20 km).- from Authors
