However, Barr et al. effectively block inclusion of the Mira belt (Mb) in Avalonia by masking a long-documented trans-Avalonian succession under locally defined lithostratigraphic names that prove to be confusing homonyms of themselves. Earlier revisions of Mira belt stratigraphy allow assignment of the Mira belt to a precise location in the Avalonian strike-slip regime—on the marginal–inner platform transition just as the northern Antigonish Highlands and southeast Burin Peninsula. The Mira belt is a tectonic inlier not a “terrane” in the A–C orogen.</div>
