Resumen:
EMPLACEMENT OF SERRA GERAL GROUP IN MISIONES PROVINCE:GEOCHEMICAL AND TEXTURAL EVIDENCES. The Paraná-Etendeka LargeIgneous Province is extended in the eastern-centre of South America and southwesternAfrica. In South America the Parana-Etendeka LIP (or Serra Geral Group) compriseslarge areas of Brazil, northern sectors of Uruguay, eastern Paraguay and northeastern ofArgentina. In Misiones province the lava stacking reaches around 1300 m and iscomposed of subalkaline basalts of two groups: of high TiO2 (between 1.5-1.8%;Paranapanema type) and a higher TiO2 group (between 3-4%; Pitanga type). TheParanapanema type is also associated with evidences of interaction of magma/wetsediments both at the outcrop (i.e.: peperites, sandstone dikes) and microscopic(quenching textures) scales; liquid inmiscibility textures are common.
