The ultramafic massif of Bulqiza,which belongs to the eastern ophiolitic belt of Albania,is a major source of metallurgical chromitite ore.The massif consists of a thick(＞4 km)sequence,composed from the base upward of tectonized harzburgite with minor dunite,a transitional zone of dunite,and a magmatic sequence of wehrlite,pyroxenite,troctolite and gabbro.Only sparse,refractory chromitites occur within the basal clinopyroxene-bearing harzburgites,whereas the upper and middle parts of the peridotite sequence contain abundant metallurgical chromitites.
