The Hirnantian-Early Llandovery transition sequence in the Paraná basin, Eastern Paraguay

The Lower Paleozoic Itacurubí Group (Harrington, 1972) is exposed in the western border of the intracratonic Paraná Basin of eastern Paraguay (Fig. 1). This group (c. 350 m thick) includes from base to top the Eusebio Ayala, Vargas Peña and Cariy siliciclastic formations. It was traditionally assign...
