Laurentian margin evolution and the Caledonian Orogeny : a template for Scotland and East Greenland
The orthotectonic Scottish Caledonides constitute only a small fragment of the Neoproterozoic to Paleozoic margin of Laurentia, albeit one which lies at a prominent bend in that margin. Sequences exposed in the Scottish outcrop include Mesoproterozoic, Neoproterozoic and Cambro-Ordovician strata whi...

The orthotectonic Scottish Caledonides constitute only a small fragment of the Neoproterozoic to Paleozoic margin of Laurentia, albeit one which lies at a prominent bend in that margin. Sequences exposed in the Scottish outcrop include Mesoproterozoic, Neoproterozoic and Cambro-Ordovician strata which record sedimentation, volcanism and deformation related to the latter stages of the amalgamation of Rodinia, the subsequent breakout of Laurentia, and growth of the Iapetus Ocean. Metamorphic and tectonic overprints then record the destruction of that ocean through Ordovician arc accretion and mid-to-late Silurian collision of Laurentia, Baltica and Avalonia with the final closure of Iapetus by end-Silurian time. New isotopic data and recent advances in the understanding of the late Mesoproterozoic (Stenian) to Cambro-Ordovician stratigraphical framework now better constrain the sequence and timing of events across the ‘Scottish Corner’ and invite a dynamic comparison with the current research into the East Greenland Caledonides summarised in this volume.
