Protodolomite redefined
Abstract
Since its introduction in 1956, the term "protodolomite" has been frequently used and frequently abused. "Protodolomite" is herein more rigorously defined as those metastable single-phase rhombohedral carbonates which deviate from the composition of the dolomite that is stable in a given environment, or are imperfectly ordered, or both, but which possess a high degree of cation-order as evidenced by the unambiguous presence of order reflections in diffraction patterns. Protodolomite appears to be an intermediate phase in the dolomitization of calcium carbonate, both in experimental and in many natural systems.

Most experimental inorganic dolomite formation studies have quantified dolomitization of calcite, other Ca-Mg carbonates, or followed proto-dolomite crystallization or dolomite growth on carbonate seed crystals, mimicking diagenetic processes.
“Most experimental inorganic dolomite formation studies have quantified the 'dolomitization' of calcite (Gaines 1977; Katz and Matthews 1977; Miura and Kawabe 2000; Nordeng and Sibley 1994; Kaczmarek and Sibley 2007), other Ca-Mg carbonates (Katz and Matthews 1977; Zempolich and Baker 1993; Sibley et al. 1994), or followed proto-dolomite crystallization (Malone et al. 1996) or dolomite growth (Gain”

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.
