Esquema Geodinámico del volcanismo de la Isla Decepción( Islas Shetland del Sur)
Deception Island volcanism is characterized by a sucession of pyroclastic and lavic materials whose lithology varying between basalts to basaltic andesites, andesites and dacitic rocks.The chemical characteristics of these show a tholeitic and low-K calc-alkaline trend. The island structure and geoc...
