Geofísica
| Resumo | Significant geological investigation has focused on the Pampean, Paraguay and Araguaia belts after a recent hypothesis suggested that they form the suture of the Clymene Ocean and the final amalgamation of the supercontinent Gondwana. This proposed ocean is located between the Amazon craton and the various craton blocks forming Gondwana (Congo-São Francisco, Goias , Rio Apa, Paranapanema, Rio de la Plata). Here we present initial field geology and geochronological results from several campaigns to the Araguaia Belt. |
| Resumo | The Brazilian Seismographic Network (RSBR) was deployed between 2009 and 2016 mainly with resources from PETROBRAS and is currently maintained by the Brazilian Geological Survey (CPRM). |
