On the Sections of the Malvern and Ledbury Tunnels (Worcester and Hereford Railway), and the intervening Line of Railroad

Abstract

In a paper published in the Edinburgh New Philosophical Journal for April 1857 (p. 257), I described briefly the “Correlation of the Triassic Eocks in the Yale of Worcester and at the Malvern Tunnel.” These rocks have the following order on the flanks of the Malverns:— 1. Upper Keuper Marls. 2. Upper Keuper Sandstone. 3. Lower Eed or Keuper Marls. 4. Lower Keuper Sandstones (Waterstones). 5. Upper Red Sandstone (Bromesberrow beds). 6. Lower Red Sandstone (Stourport beds). No. 6. The lowest of these deposits is a dark-red sandstone with black patches, and closely resembles the “Lower Red Sandstone” of the geological surveyors in mineralogieal character. It is to be seen at the back of the stables of the Belle Vue Hotel at Great Malvern, dipping from the hill, to the south-east, at an angle of 60°. A large erratic block, angular and with no sign of subaqueous action, was found imbedded in this dark-red sandstone. This erratic block is different to any rock now exposed in the Malvern district, and appears to me to belong to the Cambrian grits of North Wales, or possibly to that of the Longmynd. It may be seen in the Museum of the Malvern Field-Club at the Messrs. Burrow's, Great Malvern.
