THE PRECAMBRIAN HOLUM GRANITE, SOUTH NORWAY 23 by the limited accessibility of those areas. On the other hand, the Holum granitic pluton is well suited for an integrated geological-grav­ ity study because it combines extensive outcrops (about 50% exposed) with numerous roads and relatively low relief, especially for Size: 2MB.

A new geological map, covering about km' of the area around Farsund, south Norway, is presented. The country rock gneisses have. The Precambrian Grimstad granite, South Norway, has been studied by petro graphical, chemical and x-ray crystallographical analysis. It has a semi-circular out line and is partly rimmed by an agmatite. Eight different rock types are found within the granite, but the . investigated by NILSSEN (), and a gravity study was carried out by SMITHSON (a). Specimens collected as part of a detailed petro­ chemical study (DICKSON and BALL ) provided a basis for the re-investigation of the feldspars reported in this paper. The feldspars are presently being investigated in two stages: l) K-feldspar obliquity.
