| Abstract | (unpublished)
Keppie et al. (2021) presented a Devonian to Carboniferous oroclinal bending hypothesis and dextral strike-slip translation of a single arc terrane to explain the distribution of
Cambrian to Ordovician volcanic rocks in the northern Appalachians. We contend that extant data are incompatible with this hypothesis for reasons documented here. |
| Summary | (Plain Language Summary, not published)
Tectonic models provide a predictive framework for understanding geology and mineral potential of mountain belts. This discussion paper provides a
critique of a revised tectonic model for the development of the Appalachians that was published in Canadian Journal of Earth Sciences. On the basis of close to 30 years of GSC research in the Appalachians, we demonstrate that the revised model is
incompatible with extant data. |
