The Neoproterozoic to Mid-Devonian evolution of Scotland: a review and unresolved issues
Bibliographic record
Abstract
The purpose of this review paper is to identify and outline some critical questions about the geology and tectonic evolution of the Scottish Caledonides in their wider Caledonian/Appalachian context. We outline what we think we know and what we perceive to be some important problems from about 1.0 Ga (Grenville Orogeny) to the Middle Devonian (Acadian Orogeny). We do not attempt in-depth analyses of any terrain or tectonic topic in this review but, mainly, pose questions. Scotland is considered in the context of the Irish Caledonides and the Northern Appalachians, especially Newfoundland, so we make reference to these areas where appropriate. Each section is intended as ‘stand-alone’, not dependent upon prior or subsequent sections; the sequence of sections, roughly in time order, has a historical narrative thread. We have not included cross-sectional schematic diagrams because we do not have a clear picture of plate boundary zone and terrane arrangements in the Caledonides. There are too many enigmas, paradoxes and unknowns to draw tectonic cross-sections with conviction.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
