Iron Bearing

A reinvestigation of the native iron bearing rocks of northern Disko has been initiated as a follow up of new regional mapping. A variety of hypotheses as to formation have been put forward since the work of Steenstrup (1882a); a bibliography is given by Bøggild (1953) and a recent review by Pauly (1969). In addition to examination of the nature of the deposits as such, the purpose of the new investigations is twofold. (1) To map the native iron bearing volcanic rocks which ean be used as stratigraphical marker horizons. (2) To investigate the possibie economic potential of segregations of native iron and sulphides found in these rocks.

The purpose of the summer's field work was twofold: (a) to search for native iron and sulphide mineral assemblages in the northem extension of the Kitdlit dyke (Fundal, 1975; Pedersen, 1977a & 'a' in figs 10 & 11) and other related (sediment contaminated) dykes, and (b) to map the surrounding area as a contribution to the map sheet Diskofjord (69 V. 1 N, fig. 2). About 600 km2 were mapped in detail and 1500 km2 briefly surveyed.

Early Tertiary

The lithostratigraphy of the early Tertiary Vaigat Formation on Disko is presented. The formation is divided into six members: Naujanguit Member, Asuk Member, Kûgánguaq Member, Qordlortorssuaq Member, Ordlingassoq Member and Manítdlat Member. The members were formed by two major igneous events. The first event gave rise to the vo!canic rocks from the Naujånguit Member and two minor vo!canic systems enclosed therein: the Asuk and Kiigånguaq Members. The basalts of the Qordlortorssuaq Member constitute the waning phase of the first igneous event. The second igneous event gave rise to the vo!canic rocks of the Ordlingassoq Member within which are enclosed the alkaline basalts of the Manitdlat Member. The members are composed of the folIowing igneous rocks: Naujanguit Member: tholeiitic picrites, minor silicic basalts and olivine-poor tholeiitic basalts; Asuk Member: silicic basalts and magnesian andesites, many rocks carry native iron; Kfigånguaq Member: silicic basalts and magnesian andesites; Qordlortorssuaq Member: olivine-poor tholeiitic basalts; Ordlingassoq Member: tholeiitic picrites, minor alkaline picrites; Manitdlat Member: alkaline picrites and alkaline basalts.
