...HANNAH S. R. HUGHES; KATHRYN M. GOODENOUGH; ABIGAIL S. WALTERS; MICHAEL MCCORMAC; A. GUS GUNN; ALICJA LACINSKA Abstract In NW Scotland, several alkaline intrusive complexes of Silurian age intrude the Caledonian orogenic front. The most northerly is the Loch Loyal Syenite Complex, which is divided...

... the evidence suggests that deformation of the Loch Borralan mass resulted from late contractional slip movements on the Moine thrust. The Loch Loyal complexes are emplaced entirely in Moine schists lying at a minimum of 12 km SE of the Moine thrust belt. They are certainly post-metamorphic, and undeformed...

... character and complex geometries of many mid- to upper- crustal plutons that have been emplaced into orogenic belts at depths below the influence of the free-surface (e.g. 4 8 km; Hutton 1997). This is well illustrated by the study of the Loch Loyal syenites presented here. Based on detailed remapping...

... Abstract Christopher Talbot writes: Holdsworth et al. (1999 a ) are persuasive in their argument that the Loch Loyal syenites are different parts of the same syenite pluton exposed at different structural levels. However they also argue that emplacement of this pluton was relatively passive...

... that also lies within the Caledonian belt but some 130 km south of Loch Loyal. This complex had also previously been considered to be emplaced forcefully ( Pochin Mould 1946; Marston 1967, 1971) but has recently been remapped ( Hood 1990 and BGS 1996: NERC–BGS Academic mapping contract F60/G2/23) and re...

... throughout the region, intruding the foreland succession, within the Moine thrust zone, and less commonly in the hinterland schists of the Moine Supergroup. Two syenite intrusions, the Loch Borralan complex and Loch Ailsh complex, crop out within the thrust zone in northwestern Scotland. Both contain...

... . 2004 ). All these rocks are related to a common enriched mantle source and were probably intruded at the same time as the Loch Borralan and Loch Ailsh complexes. The Loch Loyal syenites in the northern part of the MTZ include three separate, but related, igneous bodies intruding the Moine...

... the Moine Thrust Zone. There is no discernible spatial pattern to the distribution of K–Ar ages in relation to regional structures and geological units. The Moine and Naver nappes are intruded by the Loch Loyal syenites ( Fig. 1; King 1942; Robertson & Parsons 1974). These were emplaced after...

... plutons in the Scottish Caledonides, such as the Loch Loyal Syenites ( Holdsworth et al . 1999 ) and the Foyers granite complex ( Carey & Platten 2000 ). The Clunes Tonalite clearly belongs to the regional suite of Middle Silurian intrusions identified in the Scottish Highlands by Rogers...
