Integration of regional stratigraphic relationships with data on sediment accumulation,
provenance, paleodrainage, and deformation timing enables a reconstruction of Mesozoic …

We present an updated synthesis of the widely accepted 'single-arc Pacific-origin'and
'Yucatán-rotation'models for Caribbean and Gulf of Mexico evolution, respectively. Fourteen …

The Andes make up the largest orogenic system developed by subduction of oceanic crust
along a continental margin. Subduction began soon after the breakup of Rodinia in Late …

A review of the tectonic events recorded by sediments on the Andean continental margin of
northern Peru and Ecuador and on the accreted oceanic terranes of Ecuador, allows to …

The basement of the Western Cordillera of Ecuador consists of a fragment of oceanic
plateau crust (Pallatanga) accreted to the continental margin during the Late Cretaceous …

The structure, stratigraphy and magmatic history of northern Peru, Ecuador and Colombia
are only adequately explained by Pacific-origin models for the Caribbean Plate. Inter …

The volcanic basement of the Ecuadorian Western Cordillera (Pallatanga Formation and
San Juan unit) is made up of mafic and ultramafic rocks that once formed an oceanic …

The processes of arc initiation at the margin of an oceanic plateau are remarkably well
preserved along the southern coastline of eastern Costa Rica and western Panama. We …

Abstract In the Northern Andes of Ecuador, a broad Quaternary volcanic arc with significant
across-arc geochemical changes sits upon continental crust consisting of accreted oceanic …

This paper presents 13 stratigraphic cross sections and 12 paleo-facies maps, spanning the
Cretaceous, and summarizes the Cretaceous geological history surrounding northwestern …
