Wulfenite from Ivigtut was mentioned by Gordon in 1939. Identification was based on goniometric measurements for which reason B0ggild in 1953 noted that the data might also fit those of stolzite. New finds of similar crystals were made in 1978 and again in 1979 in thomsenolite parageneses different from the one described by Gordon. X-ray and electron microprobe determinations proved the crystals to be wulfenite. The secondary parageneses in which wulfenite was found are described. A search among other thom senolite parageneses did not result in other finds of wulfenite. Wulfenite has a very limited distribution in the deposit. No definite source for lead and molybdenum could be indicated although minerals of these elements are frequently found in other parts of the deposit.
