Palaeomagnetism and tectonics of middle America and adjacent regions Part 1

Abstract

Investigations, unified under the working hypothesis of plate tectonics, have produced a revolution in the earth sciences over the past decades. The effects of this have been profound since it has lead to a reexamination of the vast amount of available geological and geophysical data and of the approach for obtaining new information.
Palaeomagnetism has played a major role in this endevour. Palaeomagnetic data have contributed to define the relative positions of crustal blocks through geological time, and constituted a compelling evidence in favour of the hypothesis of continental drift.
