Evidence of a microplate in the Southern Andes?

Mostrar todas las versiones(2)

Paleomagnetic poles for Late Paleozoic-Early Mesozoic rocks exposed in stable and possible mobile zones of Western Argentina are reported. They suggest two interpretations. One of the interpretations suggests that a mobile zone situated at about 32.1°South 69.3°West, in the Central Andes, rotated ab...

Paleomagnetic poles for Late Paleozoic-Early Mesozoic rocks exposed in stable and possible mobile zones of Western Argentina are reported. They suggest two interpretations. One of the interpretations suggests that a mobile zone situated at about 32.1°South 69.3°West, in the Central Andes, rotated about 60° clockwise after Late Paleozoic time. The other interpretation suggests that at least the Andean zone between 32.1° and 31.7° South is allochthonous and was situated in the Pacific, at tropical latitudes, in the Late Paleozoic. On this interpretation the accretion of this microplate to South America ocurred in Permo-Triassic times. © 1985. Fil:Valencio, D.A. Universidad de Buenos Aires.
