摘要

阿巴拉契亚-加里多尼亚造山带(A-C)构造内层之间埃迪卡拉末期-奥陶系盖层序列的彻底相似性定义了从北美东北部沿海到英国南部到比利时的阿瓦洛尼亚地体。然而,Barr等人通过在当地定义的岩石地层名称下掩盖长期记录的跨阿瓦洛尼亚演替,有效地阻止了米拉带(Mb)在阿瓦洛尼亚的包裹体,这些名称被证明是混淆的同音异义词。早期对米拉带地层学的修正允许将米拉带精确地定位在阿瓦洛尼亚走滑体系的边缘-内台地过渡上,就像安提戈尼什高地北部和布林半岛东南部一样。米拉带是a - c造山带中的构造断层,而不是“地体”。

Discussion: The Terreneuvian MacCodrum Brook section, Mira terrane, Cape Breton Island, Nova Scotia, Canada: age constraints from ash layers, organic-walled microfossils, and trace fossils
Exhaustive similarities in terminal Ediacaran–Ordovician cover sequences between tectonic inliers in the Appalachian–Caledonian (A–C) orogen define the Avalonian terrane from coastal northeast North America through southern Britain to Belgium. 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.
