Abstract

Based on new radiometric data, a Pre-Cañadas volcanic building of 3.5-3.0 Ma has been defined. This
new building is mainly compared of basaltic rack cropping out in several gorges to the S of Cañadas
Building, inside of the «Pared de Las Cañadas», «Boca de Tauce», and «La Grieta» and «La Angostura»
valleys. Estimated minumum diameter and maximun high is 23 Km and 2300 m respectively. The
destruction of this volcanic structure could contribute in the formation of the volcanic breccia ocurring
underneath the Tigaiga massif.
