Analysen der Schwefel isotopische Zusammensetzung (δ34S) Pyrit aus Methan-Lager Ablagerungen haben in der Regel auf Mischproben konzentriert. Hier angewendet wir sekundäre Ion Massenspektroskopie δ34S Werte verschiedener Pyrit-Generationen zum Verständnis der diagenetischen Geschichte des Pyritization zu analysieren.
