The normative mineralogy of the Loch Borralan, Loch Ailsh and Loch Loyal Ieucosyenites is compared to thesystem Ab -Or -An -Qz. At Borralan, the upper quartz-syenitesofcnoc-na-Sroine plot within the plagioclase volume, the lower perthosites within the alkali feldspar volume. This mineralogy cannot have been attained by in situ crystal fractionation. The Ailsh rocks plot within the plagioclase volume, the Loyal syenites within the alkali feldspar volume. The three complexes cannot have been derived from a single magma body at depth, and are not precisely coeval.

## Abstract The Monadhliath and Leven Schists are separated north of Glen Roy by some 500m of psammitic rock. Junctions are gradational and conformable, and evidence from sedimentary structures indicates that all three face upwards. The two schists should not be equated, nor should the Monadhliath
