The Carolina Terrane, also called the Carolina Superterrane or Carolinia, is an exotic terrane [1] running ~370 miles (600 km) approximately North-South from central Georgia to central Virginia in the United States.
The Dun Mountain-Maitai terrane comprises the Dun Mountain ophiolite belt (also called the Mineral Belt), Maitai group and Patuki mélange. [1] The Dun Mountain Ophiolite is an ophiolite of Permian age located in New Zealand's South Island .
The fault zone represents an ancient suture, the boundary where an ancient oceanic crustal block known as an exotic terrane, named by geologists the Smartville Block, collided with and attached to the North American plate. Gold
In geology, a terrane (/ t ə ˈ r eɪ n, ˈ t ɛr eɪ n /; [1] [2] in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or "sutured" to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the ...
Stikinia, or the Stikine terrane, is a terrane in British Columbia, Canada; the largest of the Canadian Cordillera. It formed as an independent, intraoceanic volcanic arc during the Paleozoic and Mesozoic .
Rocks of Wrangellia (the individual terrane, not the composite terrane) were originally created in the Pennsylvanian to the Jurassic somewhere, but probably near the equator, in the Panthalassic Ocean off the west coast of Laurentia (North American craton) as island arcs, oceanic plateaus, and rock assemblages of the associated tectonic settings.
In the late Neoproterozoic-early Cambrian, the Pampia terrane collided with the western margin of the Rio de la Plata craton, resulting in the Pampean orogeny. [10] Evidence indicates that this Pampia terrane is of parautochthonous Gondwanan origin, separated from Gondwana in an earlier event to later be re-accreted to its margin.
The terrane is located at the junction between the Western Blue Ridge and the Eastern Blue Ridge Mountains. The unique lithology ., [ 1 ] [ 2 ] [ 3 ] age, [ 4 ] and metamorphic history [ 5 ] of the MHT suggest an exotic terrane origin, unrelated to either the Laurentian or peri- Gondwanan terranes that make up most of the Appalachian Mountains.
