Skaergaardite Skaergaardite Skaergaardite is an intermetallic platinum group mineral with the general chemical formula PdCu. The mineral is named after its discovery location: the Skaergaard intrusion, Kangerdlugssuaq area, East Greenland. The mineral name was approved by the International Mineralogical Association in 2003. The mineral has also been reported in the Duluth intrusion in Minnesota and the Rum layered intrusion in Scotland. Skaergaardite is associated with igneous intrusions containing well-preserved, oxide-rich, tholeiitic gabbro. It is found as inclusions in titanian magnetite, ilmenite, pyroxenes, and plagioclase. Skaergaardite can occur as an inclusion by itself, but is more commonly found in composite microglobule inclusions
