For this reason, researchers carried out a seismic study on an ophiolite complex (Bay of Islands, Newfoundland) in order to establish a comparison. The study concluded that oceanic and ophiolitic velocity structures were identical, pointing to the origin of ophiolite complexes as oceanic crust. [4] The observations that follow support this ...
Bay of Islands Ophiolite in Gros Morne National Park, Newfoundland, named a UNESCO World Heritage Site in 1987 because of its superbly exposed complete ophiolite stratigraphic sequence [7] Thetford Mines ophiolite Complex (Thetford Mines, Cantons de l'Est, Québec, Canada) [8] [9] Asbestos ophiolite (Asbestos, Cantons de l'Est, Québec, Canada) [9]
The Samail Ophiolite, also known as the Semail Ophiolite, is a large, ancient geological formation in Oman and the United Arab Emirates in the Arabian Peninsula. [2] It is one of the world's largest and best-exposed segments of oceanic crust , made of volcanic rocks and ultramafic rocks from the Earth's upper mantle that was overthrust onto the ...
The Zambales Ophiolite Complex (also called Zambales Ophiolite) is a large, well-preserved exposure of oceanic crust located in the western portion of Luzon Island, Philippines. [1] It is considered one of the best-preserved and most studied ophiolites , offering valuable insights into the formation and evolution of oceanic crust and the ...
The Coast Range Ophiolite is an ophiolite of Middle to Late Jurassic age located in the California Coast Ranges. The form the basement of the extreme western margin of central and northern California. Exposures straddle the coast from Santa Barbara County up to San Francisco.
The Dun Mountain Ophiolite is an ophiolite of Permian age located in New Zealand's South Island. Prehistorically this ophiolite was quarried by Māori for both metasomatized argillite and pounamu which was used in the production of tools and jewellery. [2] In the late 1800s, the Dun Mountain ophiolite belt was surveyed for its economic potential.
The Smartville Ophiolite is divided into sections based on lithology that describe the origin of the rocks it is made up of. In order of increasing depth: the top most unit is called the upper volcanic unit, then the lower volcanic unit, followed by the dike complex, and the plutonic suite at the bottom.
