Chromite deposit, consisting of about 180 podiform chromite bodies that are hosted in dunite dikes. The largest orebody is 850 m long, extends downdip for 260 m, and is up to 17 m thick. The host rock is mainly dunite with minor peridotite. The deposit occurs in the elliptical NS-trending Devonian Hegenshan ophiolite that crops out over an area of 60 km2. The ophiolite units, from older to younger, are: (1) peridotite with about 1,600 dunite dikes that range form several tens to one hundred meters long; (2) cumulate dunite, peridotite, ferellenstein, and gabbro; (3) conformably overlying metamorphosed mafic lava that is about 1,500 m thick, and is intercalated with silexite and limestone layers; and (4) conformably overlying Middle Devonian cataclastic rocks, tuffs, limestones, and silexite that range up to 2,000 m thick. Some dunite dikes in the peridotite contain chromite deposits.
