The detailed mapping programme in the Motzfeldt Centre that commenced in 1982 with the Syduran project (Armour-Brown et al., 1983) continued in collaboration with the GGU Pyrochlore project in 1984 (Tukiainen, this report). The resuIts obtained during the 1982 field season enabled the various syenite units of the centre to be grouped (from older to younger) into Geologfjeld (GF), Motzfeldt Sø (MSF) and Flinks Dal (FDF) Formations (Tukiainen et al., 1984). The purpose of the work in 1984 was to study the structure and spatial distribution of the rock formations in the lesser known western and southern parts of the Motzfeldt Centre. The revised map is shown in Tukiainen (this report) and some of the more important observations are outlined below.
