Garnet provenance studies, juxtaposition of Laurentian marginal terranes and timing of the Grampian Orogeny in Scotland

Abstract

On the basis of the study of garnet provenance and mica radiometric ages it is concluded that juxtaposition of the Grampian, Midland Valley and Southern Uplands terrains had occurred on the Laurentian margin by Caradoc time (450-458 m.y.). Large rivers flowed out of the rapidly uplifting mountainous Grampian terrain, across the Midland Valley and into a Southern Uplands trench during late Ordovician time. Grampian orogenic uplift therefore occurred in post-Cambrian time, probably in early and mid-Ordovician times.
