FeO content and cell parameters of magnesite from the Rakas and Åpartjåkkå deposits, Sweden

Abstract

The composition of the magnesite mineral from the Rakas and Åpartjåkkå deposits has been studied by an electron-microprobe analyser. When calculated from the diffractometer curves, the c-parameter show no dependence upon the FeO content (0.25–8.55%) of the mineral. The cell parameters determined by the Hägg-Guinier camera, however, reveal a slight dependence on the FeO content but not at all of the magnitude described in the literature.
