The Red Sandstone-Rocks of Peel (Isle of Man)

Abstract

I. Introductory. The Red Sandstone Series, ranging along the coast eastward from Peel to Will's Strand, is faulted into the Ordovician massif of the Isle of Man, and so covered with Drift that the only clear sections are to be found along the line of cliff, and in the quarries at Ballaquane. There is, therefore, little reason for surprise that it; should have been assigned to various geological horizons. It has been referred to the Old Red Sandstone by Cumming, to the Calciferous Sandstones by Mr. Horne, and to the Permian by myself (in a paper read before the Manchester Geological Society in 1894), and by Mr. Lamplugh in 1896 to the Basement Carboniferous. It is so described by him in his Appendix to the British Association Handbook for 1896 (Liverpool), and is so represented in the Geological-Survey map of the island, and in the ¼-inch Geological Map of England and Wales, both published in that year. Since 1894, in continuation of my work in mapping the island on the 6-inch scale, I have collected further evidence as to its geological age, and have refreshed my memory by a visit to the most important localities in the Lake District where the Permians can be studied. The results of this enquiry are embodied in the following paper. II. The Lower Red Sandstones and Brockrams of Ballaquane and Creg Malin. The Red Sandstones exposed in the cliffs at Creg Malin, and in the quarry at Ballaquane, dip at
