NanoSIMS elemental maps of sulfide samples from the Mid-Atlantic Ridge show the remobilization and re-distribution of trace elements during the alteration of sulfides.
A) Irregular alteration of chalcopyrite.
B) Alteration of isocubanite along the margins.
C) Isocubanite enclosed in zoned sphalerite.
D-E) Different degrees of alteration of chalcopyrite.
F) Alteration of isocubanite.
