Análises da composição isotópica de enxofre (δ34S) de pirita de metano-rolamento sedimentos tipicamente têm incidido sobre amostras em massa. Aqui, nós aplicamos a espectroscopia de massa íon secundário para analisar os valores de34S δ de várias gerações de pirita para entender a história LGMA de pyritization.
