Abstract
I. I ntroduction . W eston-super -M are lies three and a half miles W. 25° S. of Clifton Suspension Bridge. The Carboniferous Limestone in the neighbourhood forms two ridges which stand up prominently from the surrounding alluvial flats. The southern ridge, which I term the Weston-Worle ridge, runs a little north of east from the coast, at Weston, to Worle, and is about 3 miles in length. The northern and smaller ridge, known as Middle Hope (the Woodspring ridge), lies 2 miles farther north, is about 2 miles in length, and runs almost parallel to the Weston-Worle ridge. The occurrence of contemporaneous igneous rocks associated with the Carboniferous Limestone both at Weston and at Middle Hope, lends especial interest to the district. The igneous rocks have been described by Sir Archibald Geikie and Mr. Aubrey Strahan, and also, more fully, by Prof. C. Lloyd Morgan & Prof. S. H. Reynolds. The Spring-Cove lava (Weston) has, further, been fully described by Prof. W. S. Boulton. The present paper is devoted chiefly to a detailed description of the Weston-Worle ridge. My object in examining the district was an investigation of the coral- and brachiopod-succession in the Carboniferous Limestone, in connection with my work in the Mendip area, and in continuation of the work accomplished by Dr. Arthur Vaughan in the Bristol area. In order to accomplish this with thoroughness in the Weston-Worle ridge, much detailed stratigraphical work has been necessary, owing to the fact that faulting and resultant folding have complicated the structure of the ridge. Both the stratigraphy
