Sulphides can be divided into two major groups, those which are of hydrothermal origin and those which are of sedimentary origin. The sulphides of sedimentary origin are found in greatest abundance in bituminous rocks and it is these sulphides that have been investigated in the present work. A study of the sedimentary sulphides is of special importance with respect to ore deposits because the various chemical and geological conditions present at the time of deposition, compaction, and metamorphism of the sediment can have a profound effect on the mineral associations and metal concentrations of the rocks.
