Atmospheric chemical reactions on Mars have been invoked to explain non-mass-dependent v33S anomalies (v33S = N33S30.516N34S) reported from bulk analyses of Martian meteorites. To explore this signature in detail, a new ion microprobe multi-collector technique was developed to obtain precise in situ 32S, 33S and 34S measurements of individual sulfide grains from Martian meteorites ALH84001 (s 4.0 Ga) and Nakhla (1.3 Ga). This technique permits high-precision simultaneous measurement of multiple… CONTINUE READING
