Abstract
A sample of the studied sediments is heated in a non-oxidizing atomosphere. The organic material of the sediment is then pyrolyzed and the released products are oxidized. The sulfur content of the sulfur compounds produced by this oxidation is continuously measured in relation with the temperature in the form of an electric signal. The overall sulfur content of the sample is utilized in combination with a parameter characterizing the sample to determine the degree of evolution of the organic material in the sediment.
