Effects of mechanical grinding on the texture and ...
We demonstrate that mechanical grinding of CaCO 3 leads to successive calcite-aragonite and aragonite-calcite phase transformations; the latter have not been observed before. The mechanism of these phase transformations is explained by a detailed study of the crystalline structures of calcite and aragonite.

This study of the dissolution of calcite in an acid environment demonstrates a significant dissolution anomaly for small particles. This cannot be attributed to very small, finely ground particles "stuck" to the grains, as there were too few to explain the magnitude of the observed anomaly. It is linked to the disruption resulting from the grinding.When observed in the …
