Summary

Geological cross-sections through the igneous complex (see section lines on Coloured Map and Fig. 7), from Weiss (1986) and Troll and Weiss (1991). l - metasediments. Lined patient indicates pelites and semipelites; lined pattern with dots represents quartzites. Squiggly lines indicate migmatitic rocks. The orientation of the lines gives the attitude of the bedding projected into the cross section. 2 - monzodiorites, showing flow- and deformation foliation. 3 - quartz diorites, showing alignment of metasedimentaty xenoliths. 4 - fine grained diorites with xenoliths. 5 - granites. The flue crossed ornament in the centre represents leucogranite, and the bounding stippled margin represents a gradational contact with the main granite. 6 - hybrid transition zones between granite and quartz diorite. The dotted line labelled '..Sgorr Dhearg' represents the projected topographic expression of this peak which occurs about 300 m N of the line of section.
