  • Potassium-argon ages of eight volcanic rocks from some of the geologically oldest flows exposed in the Gal�pagos Archipelago indicate that the Gal�pagos Islands have a probable maximum age of 3 million years. Rocks from six islands were dated; the oldest are from Espa�ola (3.2 � 0.2), Sante Fe (2.7 � 0.1), and Plazas (4.2 � 1.8 million years). The new data suggest that the Gal�pagos Islands are younger than previously supposed on the basis of marine magnetic anomaly dating, but they are older… CONTINUE READING
