Abstract
Nitrogen isotopes have played an important part in the acceptance of the hypothesis that SNC meteorites derive from Mars. As a result, these meteorites can be investigated for their carbon, sulphur, and hydrogen systematics with a view to learning something about the environmental conditions on the planet. Important aspects of the role of carbon, present in the form of carbon dioxide as an atmospheric gas and leading to the formation of carbonates by weathering or hydrothermal activity, can be established. The presence of indigenous organics is an intriguing possibility. A variety of new or emerging techniques which could improve our understanding of SNC meteorites and might be applied to a returned Martian sample are discussed.
