The nakhlite meteorites are samples of the Amazonian crust of Mars. They are olivine-bearing clinopyroxenites that contain veins of secondary minerals formed by pre-terrestrial water-mediated alteration. The precise origin of these veins is contentious, and a number of mechanisms have been suggested, e.g. fracture filling cementation [1, 2] and local dissolution-replacement [3]. It is also unclear whether the secondary minerals are the product of a single episode of alteration [2] or by multiple pulses of fluids [4]. In an attempt to answer these questions we have undertaken a petrographic and isotopic study of olivine-hosted secondary mineral veins in the Yamato 000593 and 000749 (Y593, Y749) nakhlites.
