The micro-fabric of some members of the “Tarskavaig-Moine” Series

Abstract

The “Tarskavaig-Moine” schists occupy a small area in the Sleat district of Skye, extending southwards from Tarskavaig to the Point of Sleat, a distance of about seven miles, with a maximum width of outcrop of two and a half miles between the coast on the west and structurally overlying formations on the east. Their tectonic relationships and petrographic characters were first described in detail by C. T. Clough in the Geological Survey Memoir on the North-West Highlands of Scotland (1, pp. 589–594, and pp. 618–621). The northern part of the outcrop falls in Sheet 71 of the one-inch geological maps, and is described in the accompanying memoir (2); the southern part falls in the unpublished Sheet 61. Later publications summarize these earlier discussions (3, p. 171; 4, p. 309; 5, p. 23); the last named includes a map of the whole outcrop, on a scale of two miles to an inch, simplified from manuscript maps by Clough. A summary of the tectonics and metamorphism has recently been published by Dr. E. B. Bailey (6).
