Detrital zircon signature of the Moine Supergroup, Scotland: Contrasts and comparisons with other Neoproterozoic successions within the circum-North Atlantic region

A total of 200 detrital zircon grains from three stratigraphically distinct samples of the Neoproterozoic Moine Supergroup, NW Scotland were analysed by ion microprobe. Samples were taken from the Lower and Upper Psammite Formations of the oldest Moine unit, the Morar Group, and one from the tectonostratigraphically overlying, and presumed younger, Glenfinnan Group. The Morar Group is dominated by Palaeo- and Mesoproterozoic crystals and minimal...
