Scientific paper

The carbonate minerals in ALH 84001 are not only extremely aesthetic in appearance but also provide us with an interesting and as yet unresolved scientific challenge - how did they form? Their importance has recently been promoted following revelations that they may have been implicated in past biological activity on Mars. Since, in this regard, it is the overall carbon budget of the sample that is relevant, we have attempted to study the relationship of the carbon in both the carbonates and the major, noncarbonate form, namely, organic compounds. To this end we have used an acid-dissolution procedure to remove carbonates selectively (by reaction to give CO2 gas), followed by analysis of the reclaimed residues.
