Molybdenite in the Fiskenæsset anorthosite complex, southern West Greenland

Abstract

During the past few seasons mapping of early Precambrian rocks in the Fiskenæsset region (Kalsbeek, this report), the author has noted the widespread occurrence of molybdenite in the Majorqap qava outcrop of the Fiskenæsset anorthosite complex. This outcrop lies 35 km north-east of Fiskenæsset town, north of Fiskenæsfjorden (Myers, 1973). EIsewhere in the Archaean rocks of Greenland, substantial amounts of molybdenite have only been found in supracrustal amphibolites in the Godthåb region by Kryolitselskabet Øresund A/S at Ivisartoq (Nielsen, 1973) and V.R. McGregor at Narssaq.
