The mineralization is associated to two processes of alteration: carbonatization and chloritization. Owe to S34S values, a biogenic origin can be attributed to these sulphides with greater hydrothermal contamination in Latedo. The changes in 8 34S values are due to the transit from a deep anoxic to another shallow and coastal environment in the sedimentary basin}, publisher = {Sociedad Geológica de España}, keywords = {8 34S}, keywords = {Sedimentary sulphides}, keywords = {Silurian}, keywords = {Zamora}, title = {834S de los sulfuros silúricos tipo "sedex" de Latedo-Sejas de Aliste (Zamora, España)}, title = {8 34S of the "sedex" type Silurian sulphides of Latedo-Sejas de Aliste (Zamora, Spain)}, author = {Timón, S.
