Un episodio volcánico pre-Cañadas en la Isla de Tenerife
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»...

| Summary: | 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. |
