Popis:	Some varieties of magnetite with relatively high content of SiO2 (about 5,4%) were found by the authors. Silica-bearing magnetite of the Korshunovskoye scarn deposit is enriched in Ca (up to 1.99% CaO), Al, Mg, Ti. In serpentinites of the Atlantic and Indian oceans Si-magnetite forms pseudomorphs on Cr-spinel and includes impurities of Mn (to 3.5% MnO), Cr, Mg and Al. Distinct quantitative correlations of silica and other trace elements are observed. The authors suggest possible models of cation distribution in Si-magnetites and suppose that emplacement of silica into the magnetite crystal structure is due to the presence of chlorine in mineral-forming solutions.
