James Ciencias de la Tierra inter Inter Pacific vs Caribbean Plate American origin Arguments in support of the Pacific origin for the Caribbean Plate are discussed along with others that point toan inter-American origin. Entry of a Pacific-derived plate would have involved unlikely, geometrically complexand highly diachronous events. They would have included changes in direction of subduction, changes in directionof plate migration, major (1000s of km) plate migration, major rotation of large parts of a volcanic arc,major rotations of the Maya and Chortis blocks and diachronous development of flysch/wildflysch deposits asthe entering plate interacted with neighbouring elements. The internal structural conformity of the CaribbeanPlate and of the Maya and Chortis blocks with regional geology of Middle America shows that no major migrationsor rotations have occurred. Coeval, regional deposits of Albian shallow water limestones, Paleocene MiddleEocene flysch/wildflysch deposits, Middle Eocene limestones, and a regional Late Eocene hiatus show aninter-American location, not a changing Pacific-Caribbean location. Neogene displacement of the Caribbeanrelative to North and South America amounts to no more than 300 km 2006 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50540216 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.1-2 Vol.4 |
