Resumen:
Samples from the Lower Paleozoic Cancañiri Formation at la Cumbre, La Paz-Bolivia (Andes Centrales), were analysed for petrography, geochemistry, dating of detrital zircons and palynology. This unit was interpreted as recycled from previous glacigenic deposits (Díaz-Martínez, 1997, 2005) probably from the latest Ashgilian to the early Llandoverian. The aim of our study is to reveal more information about the depositional setting of the succession often interpreted as one of the most significant rock section containing lithological constraints for the Hirnantian ice age in western South America.
