Abstract

During the 1950s and early 1960s the Ivigtut area was mapped by the Geological Survey of Greenland (GGU), as part of GGUs systematic mapping programme. Detailed work was carried out on the two supracrustal units in the area, and the relative age relationship of the two units was established. The younger Ketilidian supracrustal rocks outcrop in the inland area, dose to the Inland Ice, and the older Tartoq Group supracrustal rocks are found in and around Sermiligårssuk fjord. In the early 1970s Renzy Mines Ltd. conducted a mineral exploration programme in the area, during which arsenopyrite-pyrite mineralisations were found in the Tartoq Group supracrustals (Appel & Secher, 1984), and a banded ironformation was discovered in the Ketilidian supracrustal rocks (Appel, 1974). During the 1983 field season two teams from GGU undertook field work in the area, as aresult ofwhich a banded iron-formation was discovered in the Tartoq Group supracrustal rocks.
