Procedencia y edad de las diamictitas del Paleozoico inferior de la cuenca de Perú-Bolivia (Gondwana occidental)

An extensive diamictite-bearing unit is present within the lower Palaeozoic siliciclastic sequence of the Central Andes. A review of its lithostratigraphy, sedimentology and biostratigraphy allows to differentiate two subunits according to their provenance and age. The correlative San Gabán Formatio...
