Galápagos magma chambers

DJ Geist, G Bergantz… - The Galápagos: A natural …, 2014 - Wiley Online Library
Each of the seven shield volcanoes of the western Galápagos has a large caldera—direct
evidence of shallow magma chambers. The volcanoes are of three petrologic types:(1) …

Variations in crustal thickness, plate rigidity, and volcanic processes throughout the Northern Galápagos Volcanic Province

E Mittelstaedt, AS Soule, KS Harpp… - The Galápagos: A …, 2014 - Wiley Online Library
We use a compilation of new and previously collected gravity and high‐resolution, multi‐

Helium isotope variations and mantle plume‐spreading ridge interactions along the Galápagos spreading center

DW Graham, BB Hanan, JE Lupton… - The Galápagos: A …, 2014 - Wiley Online Library
Along the Galápagos Spreading Center (GSC), 3He/4He varies from 8.5–5.9 RA. High
3He/4He ratios, resembling those in the western and southern Galápagos islands, are …

A preliminary survey of the northeast seamounts, galápagos platform

CW Sinton, KS Harpp… - The Galápagos: A natural …, 2014 - Wiley Online Library
A simple plume model cannot fully explain the origin of the Galápagos Islands because
