New method for estimation of the magnesium fraction in magnesian calcite
A new method for estimation of the magnesium fraction in magnesian calcite is described. It involves measuring the XRD pattern of magnesian calcite in a narrow 2theta range and individual profile fitting of diffration lines 113 and 202. The intensity ratio I113/I202 is linearly correlated with the Mg fraction. The method resulted from an XRD study of adult sea urchins Sterechinus neumayeri.
