Abstract

The chemical state and local environment of sulphur in basaltic glasses from the eastern Galapagos rift and quenched laboratory experiments have been studied by synchrotron-radiation S K-edge XANES using an energy-selective fluorescence detector. Sulphur in melts in the system 6NaAlSiO (sub 4) -CaS-CaSO (sub 4) quenched from 1500 degrees C and various reference compounds was also investigated. The linear correlation between relative XANES area and wt% content of sulphur has been used to estimate the sulphur content in samples of lazurite (5.6-6.3 wt% by EPMA), scapolite-group minerals (0.4 wt%) and the basaltic glasses (0.04-0.15 wt%). The S K-edge spectra for glasses from the eastern Galapagos rift are dominated by S (super 2-) , but one total-electron yield spectrum shows possible thiosulphate and another, trace sulphate.
