in the Indian Ocean." Nature Geoscience published online 24 February 2013.
Fatka and Mergl provide an overview of the complex evolution of terrane terminology, and argue, largely on the basis of faunal evidence, for the existence of Perunica as a microcontinent
that is separate from the Armorican Terrane Assemblage throughout the Ordovician.
Significance of fossiliferous Middle Cambrian rocks of Rhode Island to the history of the Avalonian microcontinent
. Geology, 6, pp.
England and Thompson 1986), it is possible that some of these backarcs may have inherited the high heat flow from a recent history of extension (from which the heat has yet to dissipate) and switched to compression by the arrival of a microcontinent
or oceanic plateau at the subduction zone.
The complex history of the Appalachian orogen can be summarized in terms of processes related to the Palaeozoic closure of the Iapetus and Rheic oceans, which led to the accretion of arcs, back arcs, and microcontinents
to Laurentia (e.g., van Staal et al.
Within the Svecofennian Orogen, a mosaic of orogenic belts and microcontinents
of different age has been revealed (Skridlaite & Motuza 2001; Skridlaite et al.
The first three orogenic events are mainly the result of the successive arrival of four microcontinents
(Dashwoods, Ganderia, Avalonia and Meguma) at the Laurentian margin (Fig.
The Caledonia terrane and Brookville/New River terranes are considered to be part of the peri-Gondwanan microcontinents
of Avalonia and Ganderia, respectively (van Staal et al.
The orogenies of the New England Appalachians resulted from the collision of several microcontinents
to the Laurentian margin.
