The chromitite pods and lenses in the Ulugan Bay area occur as concordant and discordant
bodies with respect to the metamorphic banding in the peridotite. Massive, disseminated and
brecciated forms were observed. Chromites exhibit Cr/(Cr+Al) ratios in the range of 0.5-0.75
and are conspicuously low in ferric iron. Though compositional variations are rather broad, the
difference seem to be unrelated to structural level. They are metallurgical in grade and show in
general the typical composition of chromites found in Alpine type peridotite elsewhere.
