Aragonite

Calcite (polymorph of CaCO 3), as clusters or whitish balls, and white crystalline crusts of calcite frequently grow on the surface of other minerals, such as garnet or ellestadite, as reported from the western dump. It is more rarely found in the eastern dump (Figure 28.1.35).

 · Aragonite crystals range in size from 5 to 101 μm, and they are slightly coarser in the more highly altered meteorites (Fig. 2; Supplementary Table 4).They may be euhedral or subhedral (i.e., the crystals have at least one straight edge that is parallel to (1 0 0), (0 1 0) or {1 1 0} and so likely to be a crystal face) or anhedral (i.e., all crystal edges are irregular and embayed by the ...

Calcite

Aragonite, calcite and ideal dolomite become progressively less soluble, or more stable. Protodolomite may actually be less soluble than calcite. As we will see in Chapters 5 and 7 of this book, this contrast in mineral solubility, particularly during exposure at sequence boundaries, is one of the major drivers in carbonate diagenesis and porosity/permeability evolution.

Calcite and Dolomite

 · Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite produces slow or no obvious bubbling.

All of them contain calcite, whereas aragonite occurs only in the CM2.5-CM2.2 meteorites and dolomite in the CM2.2-CM2.0. All of the aragonite crystals, and most of the calcite and dolomite grains, formed during early stages of parent body aqueous alteration by cementation of pores produced by the melting of tens of micrometre size particles of H 2 O-rich ice.
