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 Cache Creek terrane (alternately known as Cache Creek Melange) [1] is a geologic terrane in British Columbia and southern Yukon, Canada. The Cache Creek Terrane consists of Carboniferous to Lower Jurassic volcanic rocks , carbonate rocks , coarse clastic rocks and small amounts of ultramafic rock , chert and argillite .
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 ...
Siletzia, from Vancouver Island (Van) to the Klamath Mountains in Oregon.The shaded area shows near-surface extent as inferred from magnetic and gravitational studies (Silberling et al. 1987; Wells, Weaver & Blakely 1998), divided into the Crescent (CR) and Siletz (SZ) terranes; the crossed dashed lines are alternate locations of CR-SZ boundary.
The recognition of the Boundary Ranges suite and the Jurassic plutons that intruded it (Tagish Lake suite) as part of Stikinia has implications for the age and character of the Stikinia–Tracy Arm terrane boundary because the Boundary Ranges and Tagish Lake suites form the footwall of a major Middle Jurassic shear zone that carried the ...
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.
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.
The Slide Mountain terrane is a late Paleozoic terrane made of a complex of oceanic rocks in northern and southern British Columbia, Canada. [1] The rocks of the terrane include Carboniferous limestones, fine grained quartz rich clastics, conglomerates and volcanic rocks. Permian Kalso Group mafic volcanics are included.
