Helium, Argon and Methane Studies: The Sunda-Banda Arc, Indonesia.

摘要

The expedition to Indonesia, led by Dr. Varekamp, consisted of the collection of high temperature volcanic gases and phenocryst-bearing lavas from 3 islands of the archipelago. The aim of the expedition was to provide helium, argon and methane isotope and abundance analysis along the strike of the eastern Sunda Arc, and to compare these results with analysis made by Dr. Varekamp on Snellius Expedition in 1984 when he collected volcanic gases from the adjacent Banda volcanic arc. In this way, it was planned to obtain a unique suite of geothermal gases contrasting the effects of oceanic crust subduction along the Sunda Arc with continental subduction along the Banda Arc. (KR)
