Repeated eastward shifts of arc magmatism in the Southern Andes: a revision to the long-term pattern of Andean uplift and magmatism

A Folguera, VA Ramos - Journal of South American Earth Sciences, 2011 - Elsevier
The Southern Andes have been built through the stacking of crustal sheets in discrete
