Stratigraphic position of the Cortaderas Formation of the Angualasto Group, Lower Carboniferous, San Juan, Precordillera

A new stratigraphic scheme is proposed for the Lower Carboniferous in the Precordillera of San Juan (northwest Argentina). On the basis of the information obtained from two main outcrops the Angualasto Group is defined, to include the El Raton, Maliman and Cortaderas formations. At its type locality...
