A List of Carbonate-Bearing Minerals
Table I: The Pure Carbonate Minerals

L. Bruce Railsback, Department of Geology, University of Georgia
with the kind help of Dr. Joseph A. Mandarino of the Royal Ontario Museum

These tables are intended to list of all known carbonate-bearing minerals for which names have been approved by the International Mineralogical Association's Commission on New Minerals and New Mineral Names. Table I lists the pure carbonate minerals, those in which only HCO3-, CO32-, OH-, or O2- account for all the negative charge. If you spot an error or a missing mineral, or if you have some other comment or query, please contact Bruce Railsback.

Introduction to these tables.
Table II: The carbonate-bearing minerals with chloride, sulfate, or fluoride.
Table III: The carbonate-bearing minerals with phosphate, borate, arsenate, or silicate.
Table IV: The carbonate-bearing minerals with multiple other anions.
Table V: Recently recognized carbonate-bearing minerals.

Under each of the following headings, minerals are listed in order of increasing charge on the most highly charged cation.

1 Notes for Railsback's use.

2 For minerals that post-date Clark's (1993) Hey's Mineral Index, volume and page on which they are reported in American Mineralogist (or other publication as noted).

3 Column number.row number.mineral number in Figure 1 of Railsback's 1999 paper on "Patterns in the compositions, properties, and geochemistry of carbonate minerals" (Carbonates and Evaporites, v. 14, p. 1-20).

4 The status of yoshikawaite is uncertain; its name has never been submitted to the IMA's CNMMN. It may be identical to other hydrated Mg carbonates, and it is not treated as a separate mineral here.

5 Until recently, plumbonacrite had not been found in nature. However, a natural occurrence in association with elyite (Pb4Cu(SO4)(OH)8) was reported in 1997 in Miyawaki, R., Matsubara, S. and Hashimoto, E. (1997): Elyite from the Mizuhiki Mine, Fukushima Prefecture, Japan: Bull. of the National Science Museum, Series C: Geology and Paleontology, v. 23, p. 27-33. Many thanks to Dr. Uwe Kolitsch of the University of Vienna for pointing out to me this new occurrence. Plumbonacrite and other PbO-carbonates are the subject of a series of three papers in Mineralogical Magazine v. 64, p. 1063-1087 (2000).

6 Clark (1993) cites unpublished evidence that barbertonite is identical with stichtite, but it is treated as a bona fide mineral here.

7 Gregoryite was recognized by the IMA's CNMMN around 1980. As of 1996, a full description had not been published (see AM 81:517), but it is retained as a mineral here.

8 Wermlandite has now been identified as a purely sulfate/hydroxyl (non-carbonate) mineral by Rius and Allman (Zeitschrift fuer Kristallographie, v. 168, p. 133-144, 1984).

9 Tarnowitzite is generally regarded as an unnecessary name for Pb-rich aragonite (see AM 65:1069), and in some cases it has been shown to be a mixture of aragonite and cerussite, so it is not included as a mineral here.

10. Breunnerite is generally regarded as an unnecessary name for Fe-rich magnesite, and sideroplesite, pistomesite, and magniosiderite are generally regarded as unnecessary names for Mg-rich siderite. None of them are included as minerals here.

11. Oligonite is generally regarded as an unnecessary name for Mn-rich siderite, so it is not included as a mineral here.

12. Tengerite-(Y) was redefined with IMACNMMN approval as Y2(CO3)3.2-3H2O by Miyakaki et al. (1993, American Mineralogist, v. 78, p. 425-432). The old formula was CaY3(CO3)4(OH)3.3H2O.

13. Georgeite was redefined with IMACNMMN approval as Cu2CO3(OH)2 by Pollard et al. (1991, Mineralogical Magazine , v. 55, p. 163-166). The old formula was Cu5(CO3)3(OH)4.6H2O.

14. Song and Moon (1998, Clay Minerals, v. 33, p. 285-296; abstracted in American Mineralogist 84:687) reported a Co-analogue of reevesite.
