XIV.— The Contact between the Granites of North Arran

I. Introduction. The granite mass of North Arran occupies an approximately circular area 8 miles by 7 miles. According to Peach and Horne (1930, p. 11), this picturesque group of mountains may be regarded as an isolated portion of the Grampian Block. The view originally expressed by Geikie (1873) that the granites were of Tertiary age is now universally accepted. The Outer Granite is almost entirely surrounded by pre-Devonian schists with the exception of about three miles of its margin on the east side, where the country rock is principally metamorphosed sediments of Old Red Sandstone age. The Outer, in its turn, completely surrounds the fine-grained Inner Granite, which, with its very irregular boundary, occupies roughly a third of the area of the coarse Outer Granite (Fig. 1). The area was included originally in Sheet 21 of the One-inch Geological Survey Map of Scotland (1901) and is now contained in the special One-inch Geological Sheet of Arran (1910).1 1. Statement of Problem. —Although the boundary of the fine-grained Inner Granite has been mapped in detail, its three-dimensional shape has not been determined or discussed, except in an extremely brief reference by Gunn (1903, p. 85) to the nature of the junctions. The purpose of this investigation has been to make this determination, if possible, from a detailed study of the junctions of the Inner and Outer Granites, and, from the evidence thus obtained, to deduce the mode of intrusion. 2. Historical. —Previous to the detailed mapping of the granite complex by Gunn of the This 250-word extract was created in the absence of an abstract The writer would like to acknowledge most cordially his indebtedness to Dr. J. E. Richey for his invaluable help in the field during part of the investigation, and to Dr. G. W. Tyrrell, whose wide knowledge of Arran geology has been freely drawn upon. Thanks are also due to the Council of the Edinburgh Geological Society for a grant from the Clough Memorial Fund towards meeting expenses incurred in the field.
