Popis:	The southern part of South America provides an excellent test area to analyse relationships between transgression-regression cycles along a passive continental margin with magmatic activity and tectonic movements of the Andean Orogen. Most of the tectono-eustatic sea-level changes recognized are related to magmatic activity, whether calc-alkaline or alkaline. The magmatic activity depends on whether tectonic convergence or extension forces are dominant.
