Summary:The authors have tested and refined classical procedures for accurate determinations of total sulphur and of sulphur in total sulphides, total sulphates, and acid-soluble and insoluble sulphates, using massive-sulphide chimney samples from the Juan de Fuca ridge. The results show convincing internal consistency. The highest soluble sulphate values were found for the Ca-rich rim of a 'black smoker' chimney. The highest concentration of acid- insoluble sulphate occurs in a pyritic sample and presumably reflects the occurrence of baryte; measured Ba and sulphate values are in good agreement for this sample.
