The Nature of Bone and Phosphate Rock [PDF]

open access: yesProceedings of the National Academy of Sciences, 1950
and has been interpreted by some workers4 as evidence for the presence of CaCO3 as a separate phase. Crystalline CaC03, however, has not been observed in bone by the very sensitive test of its high birefringence. A Geiger-counter x-ray spectrometer, moreover, gives no evidence of its presence, while one-third as much calcite as would correspond to the ...
