Abstract
A Re-Os isochron age is reported for massive sulfides from near the basal c ontact of the Radio Hill layered mafic-ultramafic intrusion in the west Pil bara Craton, Western Australia. The isochron age is 2892 +/- 34 Ma (mean sq uare of weighted deviates = 1.06) with an initial Os-187/Os-188 = 0.1265 = 0.0028. This age is in agreement with the ages of other nearby layered mafi c intrusions that are considered to have a similar geological evolution to the Radio Hill Intrusion.
