EDX spectra of Chromite, Chromian Phlogopite and Mariinskite from cotype specimen.

Locality: Malyshevskoe deposit (Mariinskoe), Izumrudnye Kopi area, Malyshevo, Ekaterinburg (Sverdlovsk), Sverdlovskaya Oblast', Middle Urals, Urals Region, Russia

Posted by: Pavel Kartashov

EDX spectra of Chromite (at the top), Chromian Phlogopite (intermediate) and Mariinskite (at the bottom) from the cotype specimen. Note that Chromite spectrum contains additional peaks originated from micas (Chromian Phlogopite and Fuchsite) inclusions in its pores - Si, Mg, Al and K. Note also, that Be don't give its peak on spectrum, so Mariinskite one show only Al and Cr peaks. But their mutual intensities are quite different from one of a chrysoberyl. Pavel M. Kartashov collection and photo.
