The disseminated sulphide mineralization is attributed to sulphur contamination derived from a sedimentary reduced sulphur source causing localized sulphur saturation of the magma.
If the coals were autochthonous, then their high sulphur content might have been significant, but the evidence suggests they were allochthonous.
Only for sulphur dioxide does the analysis suggest that trade patterns driven by environmental regulations and/or factor endowments are determining per capita emissions.
Estimated turning points are also broadly similar across specifications and are slightly higher than those estimated for sulphur dioxide.
Thus, all three terrains where the sulphur patches may occur are caused by endogenic material.
The new point we make here requires the definitions of the sulphur and carbon fractionation parameters.

Chemists had another, simultaneously operating system of classification based on the qualities and the reactions of substances - mercury, sulphur, water, earth, and salt.
