Carbonate Minerals

 · Generally, the carbonate minerals are found at or near the surface. They represent the Earth''s largest storehouse of carbon. They all are on the soft side, from hardness 3 to 4 on the Mohs hardness scale. Every serious rockhound and geologist takes a little vial of hydrochloric acid into the field, just to deal with the carbonates.

 · Sure this looks like a siderite nodule / siderite concretion. Put a few small (mm sized) grains of the grey part in about 10% HCl, if it is siderite (or contains some), they will decompose/disintegrade very, very slowly (within days) and the solution will turn green. If you have some dolomite and verified siderite at hand, try a direct comparison.

Siderite

The composition of fluids that formed the secondary mineral assemblage throughout the different nakhlites was modeled by Bridges and Schwenzer (2012). They concluded that partial dissolution of the surrounding olivine clinopyroxenites by CO 2 -rich hydrothermal fluids, with temperatures of 150≤ T ≤200 °C, pH 6–8, and a water:rock ratio ( W / R ) of ≤300, produced the initial siderite.
