DESCRIPTION:Galápagos is one of the world’s most volcanically active re
 gions\, with eruptions of basalt occurring every ~5 years (the last was in
  May 2015). Our recent research has shown that the locations of the volcan
 ic islands and diversity of magmas erupted in Galápagos is a manifestatio
 n of complex physical and chemical processes in the underlying mantle and 
 crust. I will outline how some of our new research [1-3]  --  that combine
 s geochemical data for Galápagos volcanoes with high-resolution seismic d
 atabases  --  is enhancing our understanding of the relationship between d
 eep Earth processes and volcanic\, oceanographic and biological systems\, 
 and explore how Galápagos acts as a unique natural laboratory in which to
  explore these connections.\n# Gibson\, S. A. & Geist\, D. J. Geochemical
