Abstract

This study presents updates and upgrades concerning the stable isotopic register of the Tamengo Formation, upper part of the Corumbá Group, which crops out in the meridional portion of the Paraguay Belt. This work includes detailed stratigraphic sections paired with high-resolution δ¹³C and δ¹⁸O geochemistry from two mining sites near Corumbá (Mato Grosso do Sul, Brazil).
