A limited rhombohedral calcite-rhodochrosite solid solution with a wide miscibility gap can be formed at low temperatures.
“A limited rhombohedral calcite-rhodochrosite solid solution with a wide miscibility gap can be formed at low temperatures [10, 11].”

The Thermodynamic background section (page unavailable) says that a limited rhombohedral calcite–rhodochrosite solid solution can form at 25°C. It does not establish a wide miscibility gap: it says reported results range from total miscibility to limited solubility with different gap widths, and that the extent of the solid solution remains uncertain.

Experimental — accuracy not yet measuredA variety of crystal morphologies were obtained, showing the effects of Mn2+ (even at low concentrations) on the growth of the {104} faces of calcite.
“A variety of crystal morphologies were obtained, showing the effects of Mn2+ (even at low concentrations) on the growth of the {104} faces of calcite [2, 11].”

The AFM Observations and Discussion report that Mn affects growth on calcite {10̄14} faces, including changes in step shape and a shift in growth mechanism as Mn concentration increases. Table 1 includes a low-Mn solution (0.01 mmol/L). The paper describes molecular-scale surface features, however, not a variety of whole-crystal morphologies obtained in the experiments.

Experimental — accuracy not yet measuredThe lack of agreement among (Ca,Mn)CO3 solid solutions makes it difficult to put forward reliable geochemical models.

Many inconsistent values of the solubility product for rhodochrosite have been reported in the literature.

The study of precipitation behavior in the (Ca,Mn)CO3-H2O system at 25 °C was stated in the literature as being quite problematic.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
