A thick diorite-monzodiorite sheet over 2 km in length and up to 600 m in width (fig. 35) is exposed at 50°25'E and 63°55'N, about 7 km south of Qeqertaussaq by Kangerdluarssûngûp taserssua. Several diorite dykes, some over 10 m in thickness, tie parallel to the main body and up to 300 m from it. The north-east end of the body is covered by superficial deposits whilst the south-west part has not yet been mapped out. This is therefore a preliminary account, including petrography, fie1d relations and some geochemistry, and more information will become available during subsequent field seasons.
