      The regional geology of south-central Cape Breton Island is interpreted to consist of two terranes or tectonostratigraphic zones correlative throughout the northern Appalachians. The Mira and Bras d'Or terranes have been locally defined based on stratigraphy, age, metamorphic grade, plutonism, and lithogeochemistry. For example, mylonites from the Brevard fault zone in the southern Appalachians have been sampled at different locations and dates have been obtained using several techniques: Ma, U-Pb zircon; ,,, Ma, Rb-Sr whole-rock isochron.

[J Wright Horton; Avery Ala Drake; Douglas W Rankin; IGCP Project Terranes in the Circum-Atlantic Paleozoic Orogens.]. A terrane of ancient Paleo- to Mesoarchean gneisses occurs along the southern margin of the Superior craton (Fig.

).The most extensive exposure of these rocks is in the Minnesota River Valley (MRV) of southwestern Minnesota (Fig. ), but there are also exposures in northern more is known about the MRV terrane than the northern Michigan occurrences because better exposure.

The Paleozoic Appalachians are a long-lived accretionary-collisional orogen that contains numerous accreted terranes and a complete Wilson cycle (Hatcher, ; Williams and Hatcher, ; Abbott and Raymond, ; Hatcher, a; Rankin et al., ).Previously, little evidence supported a middle to late Paleozoic orogeny in the southern Appalachians (Osberg et al., ), but.

The ‘terrane concept’ was conceived and initially applied by W Porter Irwin (United States Geological Survey) to explain complex geologic relationships in the southeastern Klamath Mountains of uently, the concept has been utilized throughout the western North.

The sequences in some of the provinces are very different--for example, those in the Lake Superior region and the Coastal Plains--but others partly overlap in age, and correspondence between these from one legend to another is not always clear.

The so-called "Carboniferous" granites shown in the Southern Appalachians on the map are now. hydrothermal fluids carry dissolved carbon dioxide as well as chemical substances that are soluble in hot water under pressure. As hydrothermal solutions percolate up to the shallower parts of the crust, they react with the rocks they penetrate, changing their chemical and mineral compositions and sometimes completely replacing one mineral with another without changing the rock's texture.

The southern Appalachian orogen contains most of the subdivisions that characterize a classic collisional orogen: A foreland fold-and-thrust belt (Cumberland Plateau and Valley and Ridge), high-grade metamorphic core (central to eastern Blue Ridge and western Piedmont), and a plutonic.
