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 ...
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 Wrangellia terrane (named for the Wrangell Mountains, Alaska) is a crustal fragment ...
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 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.
The Narooma terrane or Narooma Accretionary Complex is a geological structural region on the south coast of New South Wales, Australia that is the remains of a subduction zone or an oceanic terrane. It can be found on the surface around Narooma , Batemans Bay and down south into Victoria near Mallacoota .
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 .
Part of the last major exotic terrane acquired by the North American Plate during the Eocene lies under the Tryon Creek watershed. The terrane consisted of a chain of seamounts that by 34 million years ago was being uplifted to become the Oregon Coast Range and the Tualatin Mountains (West Hills). [13]
