New Rock-Eval method for Pyritic and Organic Sulphur quantification : Application to study Organic Matter preservation in Jurassic sediments

Abstract : This study was focused on development of the new Rock-Eval 7S which presents the same functionalities as the current version (Rock-Eval 6), complemented by a system of sulphur detection during the two phases of the analysis: pyrolysis phase and oxidation phase. The main goal of this PhD project was to provide and highlight different carbon and sulphur Rock-Eval 7S parameters which can be used to describe OM preservation in marine sediments. To reach this goal, a new Rock-Eval method for sulphur speciation and quantification was developed, and validated on a set of marine sediments and on sedimentary mixtures. This new method was then used to help the description of organic matter preservation in three marine sedimentary sections: (i) Kimmeridge Clay Formation; Grey Shale Member; (iii) Blue Lias Formation. This PhD project aims to lay the scientific foundation to apply Rock-Eval 7S carbon and sulphur parameters as routine descriptors in basin models.
