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… 
Geology of Galapagos
This paper reviews the origins and geological history of the Galapagos Islands. The islands arose from a ‘hot-spot’. The oceanic crust on which the islands are built can be no more than 10 million
Plume-asthenosphere mixing beneath the Galapagos archipelago
Although the Galapagos Islands have long been cited as an example of intraplate volcanism resulting from a mantle plume1,2, a number of features of the Galapagos appeared to conflict with a simple
Geochronology of Galfipagos seamounts
Lavas from seamounts of the central Galfipagos Platform and the Carnegie Ridge increase in age with distance from the western edge of the platform, consistent with a hotspot model for the generation
Geologic Youth of Gal�pagos Islands Confirmed by Marine Stratigraphy and Paleontology
TLDR
Six distinctive types of fossiliferous marine deposits occur on the Gal�dpagos Islands that provide evidence for the age of emergence of the islands above sea level and hence a maximum age for the islands' terrestrial biota, indicating that the islands emerged from the sea relatively recently.

Origin of Espa�ola Island and the Age of Terrestrial Life on the Gal�pagos Islands
TLDR
Geological studies of Espa�ola (Hood) Island, Gal�pagos, Ecuador, indicate that the island had a subaerial rather than a submarine origin, and terrestrial life may have existed or arrived on the Gal �pagos Islands at least 3 million years ago, more than twice as long as had been assumed.
