The timing of sedimentation and Buchan metamorphism in the Grampian Terrane in Scotland from 40Ar/39Ar apparent age spectra

Stenhouse, Iona; Forster, Margaret; Lister, Gordon

Description

New 40Ar/39Ar geochronological data from the Buchan and Barrovian metamorphic sequences on the NE coast of Scotland have been obtained from in vacuo step-heating experiments conducted on white mica extracted from seven samples. The results confirm the synchronous formation of the Barrovian and Buchan metamorphic sequences, with the 40Ar/39Ar apparent age spectra obtained for samples of andalusite grade and higher recording a range of ages between 470.4 ± 1.8 and 464.6 ± 1.3 Ma. These ages are...[Show more]
