Natural samples often exhibit isotropic electron spin resonance (ESR) signals at g = 2.0006 (CO^-_2) and g = 2.0057 (SO^-_2). Electron nuclear double resonance (ENDOR) data were collected for various calcitic or aragonitic samples of marine origin. The small and isotropic ^1H hyperfine ENDOR splitting (250-350 kHz) is explained by a locally disordered water environment for these species. As for the isotropic CO^-_2 and CO^-_3 radicals in synthetic monohydrocalcite and apatite, the radicals are most probably located in the occluded water embedded in these samples, and not in the crystal matrix.
