Timing of deposition, orogenesis and glaciation within the Dalradian rocks of Scotland: Constraints from U-Pb zircon ages

From: Journal of the Geological Society | Date: January 1, 2002| Author: | Copyright information

Abstract: The stratigraphical and structural continuity of the Late Proterozoic Dalradian rocks of the Scottish Highlands is re-examined in the light of new U-Pb zircon ages on the tuffs belonging to the Tayvallich Volcanic Formation (601 +/- 4 Ma), and on the late Grampian `Newer Gabbros' (470 +/- 9 Ma) of Insch and Morven-Cabrach in Aberdeenshire. These age data, together with the existing 590 +/- 2 Ma age for the Ben Vuirich Granite, provide key radiometric constraints on the evolution of the Dalradian block, and the implications arising from these ages are critically assessed. Three main ...
