Vm. Minaev et al., ACTIVATION METHOD FOR DETERMINING THE CARBON CONTENT OF NATURAL CRYSTALS, Journal of radioanalytical and nuclear chemistry, 189(1), 1995, pp. 147-155
A method for determination of carbon content in natural silicate cryst
als has been elaborated using the C-12(d,n)N-13 reaction. Etching of c
rystal surfaces by acid solutions is proposed to remove the pollutant
surface layers. Carbon contents varying from 8 to 100 ppm were measure
d for olivine, orthopyroxene and garnet crystals.
