DOI: 10.1016/j.gsf.2017.01.009
Abstract: Abstract Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamic scenario assumed for the period 800–700 Ma is related to… read more here.

DOI: 10.1016/j.gsf.2020.07.001
Abstract: Abstract Early Paleozoic accretionary orogens dominated the Western Gondwana margin and were characterized by nearly continuous subduction associated with crustal extension and back-arc basin development. The southwestern margin is represented by Famatinian and Pampean basement… read more here.

DOI: 10.1016/j.jsames.2017.03.008
Abstract: Colonization of the infaunal ecospace by burrowing bilaterians is one of the most important behavioral innovations during the Ediacaran-Cambrian transition. The establishment of vertical burrows by suspension feeders in high-energy nearshore settings during Cambrian Age… read more here.

DOI: 10.1016/j.precamres.2021.106212
Abstract: Abstract Despite their importance in constraining the dynamics of Gondwana’s final phase of assembly, Cambrian paleomagnetic data from Gondwana are sparse. The Cambrian paleomagnetic dataset of Western Gondwana is especially poor, being defined by only… read more here.
