Морфоструктура Эквадора

Аннотация

The paper discusses general outlines of morphostructures' evolution and transformation in the Equadorian Andes and adjacent regions. Several morphostructural zones are distinguished: platformian plain of Amazonia, the Andes, coastal ranges and depressions. The topographic units came into being due to the orogenesis phase in the Miocene - Early Pliocene, and were later reactivated during the Late Pliocene - Pleistocene. The mechanism of the Equador morphostructures formation is described most adequately by the model of pulsatory waves. The plate tectonic model cannot explain many geological characteristics of both the land and the Pacific floor. There are inherited, reactivated and inversed morphostrucmres in different regions of Equador.
