There are also abundant blebs of sulphides (chalcopyrite, pyrrhotite and pentlandite, inferred to have crystallized from homogeneous monosulphide globules), often enclosed by ilmenite and magnetite.
Evolved hydrogen sulphide was carried in a nitrogen stream to a silver nitrate trap and precipitated as silver sulphide.
Analytical errors: extractions + 0.4 (2), physically separated sulphides + 0.2 (2).
The majority of these are rhyolitic/dacitic/trondhjemitic and basaltic, commonly hosting massive sulphide deposits of economic importance.
Because of their high density, the mechanisms for moving sulphide liquids upwards must involve very high flow velocities.
The relative abundance of sulphide droplets suggests that the melts were sulphursaturated just before and immediately after emplacement.
Trials were run over three years, with carrion bait presented in the presence and absence of sodium sulphide.
Sulphides are rare and there is no clear correlation between the platinum-group minerals and the sulphides.
