Metasomatic reactions between carbonated plume melts and mantle harzburgite: the evidence from Friday and Domingo Seamounts (Juan Fernandez chain, SE Pacific)

Metasomatic reactions between carbonated plume melts and mantle harzburgite: the evidence from Friday and Domingo Seamounts (Juan Fernandez chain, SE Pacific)

Two submarine volcanoes (named Friday and Domingo) have been mapped and sampled to the west of the youngest island (Alexander Selkirk) in the Juan Fernandez chain, SE Pacific. Samples from the seamounts are fresh, highly vesicular olivine and plagioclase-phyric basanites.
