Abstract Four conditions are commonly accepted as being needed for the development of native sulphur deposits in sedimentary rocks:
(1) ample sulphate-bearing evaporite, normally hydrostatic;
(2) proximity to petroleum deposits;
(3) a hydrodynamic system of communication between these two;
(4) a stratigraphic or structural trap to prevent escape of the sulphur and sulphur-bearing reaction products.
When any of these requisites are absent, apparently no significant residual bio-epigenetic sulphur deposit will form. These requirements are, however, satisfied in some areas, which include both the Triassic and Devonian evaporites of northeastern British Columbia.
