Ophiolitic podiform chromitites for a long time have been considered as “cumulates” formed by harzburgite-melt interaction and related melt mixing at the upper part of the suboceanic mantle to the Moho transition zone.Within many existing concepts,which are in a focus of this workshop,there is one suggesting that some portion of chromitites originate from deep mantle,where Cr-spinel was represented by its high-pressure polymorph with Ca-ferrite(Ca2+Fe3+2O4)structure,or these high-pressure chromitites are products of mantle recycling containing relicts of ultrahigh pressure minerals.
