Abstract

Fluids in a near-surface environment on Mars were responsible for the formation and alteration of many minerals in the nakhlite meteorites. Halite is one of a range of such secondary minerals that includes clays, carbonates, sulphates, oxides, and iron oxy-hydroxides which may have formed at different times, under different fluid flow regimes (groundwater, hydrothermal, crater lake), experiencing a range of water-rock ratios, evaporative histories, and varying degrees of interaction with the atmosphere and bedrock.

We present here the results of a combined computed tomography and electron microscopy investigation focusing on the formation of halite in the Nakhla meteorite.
