| Summary: | Zinc- and manganese-bearing chromites and associated grossular from Zimbabwe ZINC-RICH chromites have been reported from relatively few localities, and some of these have been discredited in the light of modern analytical techniques. Moore (I977), for example, showed by detailed electron microprobe analysis of Donath's original samples that the supposed zinc-rich (up to 2.6 ~o) chromites from the Helgeland area, Norway (Donath, i93i) contain only up to o.3~o ZnO. Moore suggested, therefore, that the Outokumpu deposit of Finland might be a unique location for zinc-rich chromites, and emphasized that a very unusual geochemical environment must have been necessary for their formation. |
