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 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 .
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]
This led to Lyell's concept of geological history being developed. His book Elements of Geology from 1830 to 1833, was translated into Spanish by Ezquerra del Bayo in 1847. This was used as a textbook, as it was the first modern geology text available for the general public in Spain. This spread Lyell's ideas and terminology. [50]
The Meguma terrane, also known as Megumia, is a terrane exposed in southern Nova Scotia, that became joined to the present North American landmass as part of the Appalachian orogeny. The exposed part of the Meguma terrane, the Meguma Group , is largely composed of c. 10 km (6.2 mi) thick Cambrian to Ordovician turbidites that have been ...
The Hunic superterrane is a terrane that is now attached to Europe and Asia. At the end of the Ordovician or beginning of the Silurian it separated from Gondwana and joined Laurasia at the beginning of the Carboniferous, at the time of the Variscan orogeny. Rather than being a single block, there were apparently two groups of blocks, the ...
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.
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.
