Melonite is reported for the first time in Norway from two old prospects showing copper mineralization at Middavarre, Burfjorden, northem Norway. The mineralization occurs as steeply dipping parallel quartz-calcite veins in greenstone of Precambrian age. The mineral paragenesis in which melonite occurs is chalcopyrite, pyrite and, in accessory quantities, violarite, pentlandite, magnetite, sphalerite and millerite. Results of microprobe analysis and reflectance measurements for melonite are given and it is shown that Middavarre melonite is stoichiometric with the formula NiTe2.
