Fossil marginal basin in the southern Andes
Abstract
In the southern part of the South American continent a marginal basin opened behind an active andesitic island arc in the earliest Cretaceous. The basin closed again in the middle Cretaceous, during the period of fast seafloor spreading, causing the penetrative deformation of the southern Andean Cordillera.
