The sulfur solubility minimum and maximum in silicate melt

EC Hughes, LM Saper, P Liggins… - Journal of the …, 2023 - lyellcollection.org
The behaviour of sulfur in magmas is complex because it dissolves as both sulfide (S2−)
and sulfate (S6+) in silicate melt. Interesting aspects of the behaviour of sulfur are the …
