Analyses de la composition isotopique du soufre (δ34S) de pyrite de méthane-sédiments portent généralement sur des échantillons en vrac. Ici, nous avons appliqué la spectroscopie de masse des ions secondaires pour analyser les valeurs de34S δ de différentes générations de pyrite à comprendre l’histoire diagénétique de pyritisation.
