DOI: 10.1016/j.precamres.2019.105477
Abstract: Abstract Geochronological data of Palaeoproterozoic carbonates with δ13C values between +5‰ and +16‰ suggest that the positive carbon isotope excursion of the global Lomagundi-Jatuli event (LJE) occurred mostly between 2220 and 2060 Ma. In the southern… read more here.

DOI: 10.1029/2018tc005148
Abstract: We conducted a magnetotelluric (MT) study from Paleoproterozoic Rio de la Plata Craton, in Uruguay, toward Paleozoic‐Mesozoic Paraná Basin, in Brazil. The 850‐km‐long MT transect comprises 35 evenly spaced broadband electromagnetic soundings sites. In the… read more here.
