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 ...
The Buffalo Head terrane (BHT) is a terrane in the western Canadian Shield in northern Alberta. It is covered by 1,600 m (5,200 ft) of Devonian and Cretaceous sediments and its centre is intruded by the 88–86 Ma kimberlites of the diamondiferous Buffalo Head Hills kimberlite province. [1]
The terms "Cathaysia", "Cathaysialand" and "Cathaysia Terrane" have been used by various authors for different continental blocks or terranes and assemblages thereof. . During the Devonian, the South China and Indochina continents had separated from Gondwana and they collided during the Carboniferous to finally form a superterrane in the P
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 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. [1]
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas Fault that defines the western extent of the assemblage. [1]
The Wrekin terrane is one of five inferred fault bounded terranes that make up the basement rocks of the southern United Kingdom. The other notable geological terranes in the region are the Charnwood Terrane , Fenland Terrane , Cymru Terrane and the Monian Composite Terrane . [ 1 ]
