Hyperspectral cathodoluminescence imaging of modern and fossil carbonate shells [PDF]
, 2006 Optical cathodoluminescence (CL) is commonly used to identify diagenetically altered carbonate fossils, yet such an interpretation is problematic as present-day carbonate shells may also luminesce.

The crystallographic structure of dental enamel and related apatites [PDF]
, 1964 PhDSynthetic, biological and mineralogical carbonate-containing apatites have been studied, principally by infra-red absorption spectroscopy (using polarised or unpolarised radiation), The substitution of a carbonate ion for two hydroxyl ions in the ...

Carbon and Strontium Abundances of Metal‐poor Stars [PDF]
The Astrophysical Journal, 2007 We present carbon and strontium abundances for 100 metal-poor stars measured from R$\sim $7000 spectra obtained with the Echellette Spectrograph and Imager at the Keck Observatory. Using spectral synthesis of the G-band region, we have derived carbon abundances for stars ranging from [Fe/H]$=-1.3$ to [Fe/H]$=-3.8$.

Microbial formation of crystalline strontium carbonate [PDF]
FEMS Microbiology Letters, 1994 Pseudomonas fluorescens appeared to grow in a mineral medium containing strontium (5 mM) complexed to citrate, the sole source of carbon, without any evident inhibition in cellular yield. Atomic absorption studies showed that the divalent metal was excluded from the cytoplasmic component and was initially found in the supernatant fluid in soluble form ...
