Dolomitization of linrestone with MgCl2 solution at 150.DEG.C.. Preserved original signatures of rare earth elements and yttrium as marine limestone.
Open accessAbstract
We have studied the mobility of rare earth elements (REE) and yttrium during dolomitization of marine limestone in reaction with MgCl2 solution at 150°C for 10 and 20 days. On the experiment using the pulverized limestone of 7.5 g and 25 ml of 2 M MgCl2 solution, 90% of the calcite transformed into dolomite at 150°C within 20 days. The dolomitized products showed that there is no significant change of REE abundances of original marine limestone. This is experimental evidence for the field observation that dolostones sometimes preserve the REE and Y signatures of limestone precursors.

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.
