Method for distinctly characterizing and quantifying the pyritic sulfur and the organic sulfur of a sedimentary rock sample.

A rock sample is subjected to a heating sequence in an inert atmosphere, the effluents resulting from this heating in an inert atmosphere are continuously oxidized, the SO₂ released is continuously measured, and a pyrolysis sulfur content and a pyrolysis pyritic sulfur content are deduced therefrom. The residue from heating in an inert atmosphere is then heated in an oxidizing atmosphere, the SO₂ released is continuously measured and at least an oxidation sulfur content is deduced therefrom. The pyritic sulfur content is determined from the pyrolysis pyritic sulfur content and from a weighting function taking account of a first parameter representing a pyrite thermal degradation rate, a second parameter representing the impact of the mineral matrix and a third parameter representing the impact of the organic matrix. The organic sulfur content can further be determined from at least the oxidation sulfur content, the pyrolysis sulfur content and the pyritic sulfur content.
