Abstract
The results from the electron paramagnetic resonance (E.P.R.) spectra of maganese in fourteen natural and synthetic carbonate minerals show that manganese exists as Mn 2+ in highly ionic lattice sites which are isolated in the carbonate mineral and slightly distorted from octahedral symmetry. There are two lattice sites for Mn 2+ in dolomite and they are assigned as the Mg 2+ and Ca 2+ substitutional sites for Mn 2+. The E.P.R. spectra show that the Mg-site is more populated than the Ca-site. From the results of the spectra of Mn 2+ in sedimentary and hydrothermally altered dolomites from the Leadville Formation of Colorado, it is found that the concentration ratio of Mn 2+ in the Mg-site to Mn 2+ in the Ca-site increased with alteration.
