An ion microprobe was used to perform in-situ measurements of the sulfur isotopic compositions of sulfide minerals in seven samples of hydrothermally altered rocks from DSDP/ODP Hole 504B. The sulfides exhibit a wide range in d34S values, from -4.1 per mil to + 8.3 per mil. Heterogeneities exist among different sulfide grains in a given sample as well as within individual grains. A transect across a centimeter-size pyrite crystal reveals d34S values that span the...
