Corumba Meeting 2013: The Neoproterozoic Paraguay Fold Belt (Brazil): Glaciation, iron-manganese formation and biota, an IGCP Workshop and Field Excursion on the Ediacaran system

Neoproterozoic sedimentary basins in Brazil, including glaciogenic deposits of Cryogenian and Ediacaran affinity, occur onthe São Francisco, Rio de la Plata, and Amazonia cratons. Detailed correlation of these units, however, is complicated by the tectonic traffic that resulted in the intervening mobile belts, dearth of radiometric constraints, and the lack of continuous (and uncovered) outcrop in temperate and tropical environments. Nonetheless, many of the Ediacaran sections are richly fossiliferous containing important lagerstaette of the earliest biomineralizing organisms on Earth, including Cloudina and Corumbella.
