Abstract

Reflectance spectroscopy in the visible and near infrared (0.35–2.55 um) offers a rapid, inexpensive, nondestructive technique for determining the mineralogy and gaining information on the minor element chemistry of carbonate minerals and rocks. Spectra of all commonly occurring anhydrous end‐member carbonate minerals contain seven strong absorption bands at wavelengths >1.6 um due to vibrations of the carbonate radical. Positions, widths, and spacing between carbonate bands are diagnostic of mineralogy. Differences in positions of carbonate bands between spectra of different minerals are primarily due to differences in mass of the major cation, with cation electronegativity playing a secondary role. Spectra of calcite group minerals may contain absorption features due to transition metal cations such as Fe and Mn, which can also aid in mineral identification. Spectra confirm the occurrence of both cations in the divalent state. Fe 2+ produces a broad feature near 1.1 um whose position and degree of doubling are related to the size and degree of distortion of the octahedral site, as predicted by crystal field theory. Mn 2+ and Fe 2+ produce very strong absorption bands in the minerals for which they are the major cation (rhodochrosite and siderite, respectively), making it easy to distinguish these from other carbonate minerals, even when presence of water bands may make it difficult to determine accurately carbonate band positions.

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.
