Ruby-and sapphirine-bearing mineral occurrences at Fiskenaesset area, and Nuuk and Maniitsoq regions, West Greenland
The Fiskenaesset anorthosite complex in the Archean block of West Greenland hosts many ruby/sapphirine occurrences. These occurrences furthermore contain other rare minerals such as kornerupine, gedrite, enstatite, cordierite, red spinel, pargasite and phlogopite. The report describes the geological setting of the ruby/sapphirine occurrences, mostly found in ultramafic layers and lenses along the contacts between anorthosite and amphibolite.
