New observations on the easternmost extension of the Gardar supracrustals (Eriksfjord Formation), South Greenland

During the 1984 field work in the Motzfeldt Centre of the Igaliko Complex, some of the remnants of the supracrustal rocks of the Eriksfjord Formation were investigated. These occur at several localities bordering the centre, and are also found as inclusions (roof rafts) of variable size within the syenites of the centre. These supracrustal rocks form the easternmost extension ofthe sandstones and lavas ofthe Eriksfjord Formation, the major part of which is found on the Narssaq peninsula to the west. Some of the easterly remnants were described by Emeleus & Harry (1970) who noted the occurrence ofsandstone and volcanic breccia, agglomerate and lava flows and described two small agglomerate-filled volcanic plugs. Our observations extend those of Emeleus & Harry (1970).
