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 ...
A large number of Merrimack terrane rocks are west-dipping and date to the Silurian, including the Oakdale and Eliot formations or the Paxton schist. The Ware Belt is part of the larger terrane, characterized by west-dipping schists, the four-mile wide Hardwick pluton and the Coys Hill granite.
Geologic map depicting the Smartville Complex (in brown) and other accreted terranes in California. [1]The Smartville Block, also called the Smartville Ophiolite, Smartville Complex, or Smartville Intrusive Complex, is a geologic terrane formed in the ocean from a volcanic island arc that was accreted onto the North American Plate during the late Jurassic (~160–150 million years ago).
Carolina terrane - map. 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 Yukon–Tanana Upland is a physiographic province mostly underlain by rocks of the Yukon–Tanana Terrane. [2] Understanding and definition of the YTT is constantly progressing, the term "Yukon Tanana composite terrane," or "YTCT" is used by some workers, reflecting the disparate depositional and tectonic histories being recognized in rock ...
In structural geology, a suture is a joining along a major fault zone, of separate terranes, tectonic units that have different plate tectonic, metamorphic and paleogeographic histories. The suture is often represented on the surface by an orogen or mountain range.
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 .
The Wrekin Terrane is bounded to the west by the Welsh Borderland Fault System and to the east by the Malvern Lineament. The geological terrane to the west is the Cymru Terrane and to the east is Charnwood Terrane. [1] The majority of rocks in the area are associated with the outcrops that are evident at the faulted boundaries. [2]
