Opis: The Geology of the Fannich Mountains and the Country Around Upper Loch Maree and Strath Broom - Peach Benjamin Neeve

Excerpt from The Geology of the Fannich Mountains and the Country Around Upper Loch Maree and Strath Broom: Explanation of Sheet 92

This Memoir describes the geology of the area included in Sheet 02 of the one-inch map of Scotland. It comprises the mountainous ground bounding the upper part of Loch Maree and extending northwards to Gruinard Bay and the head of Loch Broom, the Fannich mountains in the south-east quadrant, and that part of the main watershed of the Highlands situated to the east of Strath Broom. This elevated region forms part of the county of Eoss, but formerly it contained small outlying portions of the county of Cromarty.

The belt of complication due to the post-Cambrian movements crosses the sheet from Loch Broom to the alluvial plain at the head of Loch Maree. To the west of this belt lie large tracts of Lewisian Gneiss and Torridon Sandstone overlain unconformably by the Cambrian formation. To the east there is a great development of the Eastern Schists, which give rise to some of the wildest scenery in Central lloss-shire. In the north-west corner of the map there is a small patch of Triassic and Liassic strata, let down against the Torridon Sandstone by a large fault.

The Sheet was surveyed geologically by B. N. Peach, J. Home, the late W. Gunn, C. T. dough, L. W. Hinxman, H. M. Cadell, E. Greenly, T. I. Pocock, and C. B. Crampton. The largest part was done by the late Mr. Guim, whose area extended from the Fionn Loch north to Gruinard Bay, thence eastwards by An Teallach, Strath Beg, and Strath Broom to Beinn Dearg, and southwards to the watershed of the Fannich mountains. Messrs. Peach and Home took part in the mapping of the belt of complication due to the post-Cambrian movements from Strath na Sheallag to the southern margin of the Sheet. Dr. Peach also surveyed the Eastern Schists around Fionn Bheinn, and Dr. Home the development of these rocks along the southern slope of the Fannich range. To Mr. Clough was assigned the complicated tract of Lewisian Gneiss stretching from Loch Maree to Beinn a' Chaisgein Beag; to Mr. Greenly, some isolated areas near Loch na Sheallag, the Heights of Kinlochewe, and on either side of Loch Maree; to Messrs. Hinxman, Pocock, and Crampton, parts of the Eastern Schists in the north-east and southeast corners of the map, and on Beinn nan Kamh near the head of Loch Fannich; and to Mr. Cadell, a patch of Torridon Sandstone along the north-east shore of Little Loch Broom.

Detailed descriptions of the Lewisian, Torridonian, and Cambrian rocks, and of the tectonics of the belt of complication, have already appeared in the Memoir on "The Geological Structure of the North-West Highlands," which are here reproduced in a condensed form with some of the horizontal sections.
