Fornós Ciencias de la Tierra Back arc basins Island arcs North Pacific Plate convergence We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs,spreading ridges and arc-shaped mountain belts around the North Pacific Ocean. According to our model, theellipsoidal-shaped Paleogene basins of the South China Sea, Parece-Vela Basin, Shikoku Basin, Sea of Japanand the Sea of Okhotsk in addition to those of the North American Cordillera can be attributed to the change inplate convergence direction at 42 Ma between the Indoaustralian and Eurasian plates. The new direction of convergencewas parallel to the eastern continental margin of Asia and resulted in widespread extension perpendicularto this margin and to the western margin of North America. Both margins form part of a circle parallel tothe Indoaustralian-Eurasian direction of convergence. 2004 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50520302 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.2 |
