... in the Northern Highlands which lie above the Sgurr Beag thrust, that is, those previously assigned to the Glenfinnan or Loch Eil divisions, should be referred to a single tectonostratigraphic unit, the Sgurr Beag nappe. The Glenfinnan and Loch Eil divisions have the status of lithostratigraphic groups within...

... that the Naver and Sgurr Beag nappes had different sediment sources and so may not correlate. The Morar Group is dominated by late Palaeoproterozoic detritus with lesser amounts of Grenville-aged detritus. The Glenfinnan and Loch Eil Groups appear to have roughly equal proportions of detritus from the two...

...M. Krabbendam; A. G. Leslie; K. M. Goodenough Synopsis The Caledonian Orogen in northern Scotland comprises two major thrust nappes: the Moine and the Sgurr Beag Nappe. The Moine Nappe contains early Neoproterozoic Morar Group rocks (Moine Supergroup) and basement inliers. This paper describes...

.... This is the earliest structure that we have identified within the Sgurr Beag nappe, and is here assigned to S1 SB ( Fig. 8 ). The migmatitic leucosome layers have been deformed into asymmetric augen within the Sgurr Beag Thrust shear zone (see also Kelley & Powell 1985 , fig. 2 ). This clearly shows...

...John A. Winchester Abstract Discriminant trace-element geochemistry has been used to match early amphibolite suites in the Caledonide nappes lying below and above the Sgurr Beag Slide, a major low-angle dislocation in northwest Scotland. This method may be attempted in any structurally complex area...
