Abstract

The Triassic sequences exposed in the Cerro Cacheuta, are main1y composed of coarse grained epiclastites. Five sedimentary facies were defined: 1- Clast-supported conglomerates and diamictites, 2- Yellow a1temating sandstones and pelites, 3- Clast-supported conglomerates and lenticular sandstones, 4- Dark pelites and 5- Pink and purp1e sandstones. The paleofloristic association is composed of 64 taxa: Bryophyta, Lycophyta, Sphenophyta, Ginkgophyta and Coniferophyta. Based on stadistical treatment of the biocrons the following ages have been defined for the Triassic units: Potrerillos Formation (Late Middle Triassic to Early Upper Triassic): Cacheuta Formation (Early to Late Upper Triassic and Río Blanco Formation (Late Upper Triassic).
