Eulysites and related rock types from Loch Duich, Ross-shire
Published online by Cambridge University Press: 14 March 2018
Extract
Our knowledge of the rare rock type eulysite (A. J. Erdmann, 1846) comes almost wholly from Swedish occurrences amt hitherto no examples have been recognized from Britain. It is therefore of interest to place on record a new Occurrence of eulysites and related rocks from among Lewisian rocks of the Glenelg area, Scotland.
The rocks shortly to be described come from the vicinity of Totaig on Loch Duich between Totaig and Letterfearn, little more than half a mile from the first described occurrence of eclogite in Britain. These eulysitic rocks crop out on the hillside immediately south-west of Druideig Lodge. About 200 yards south-west of the lodge coarse garnet-paragneisses form outcrops associated with grunerite- and cummingtonite-garnet-gneisses, and a similar interbanded association is found at higher levels.

page 342 note 1 Direct confirmation of these figures is much to be desired. Joliffe's results include metagreenalite and are obtained indirectly. Gruner (Amer. Min., 1936, vol. 21, p. 205) states that X-ray powder photographs of greenalite resemble those of serpentine.
