Not illustrated. 1901 Excerpt: ...This division forms a belt of variable width surrounding the great Lanarkshire coal-field on the north, west, and south sides. Frequently the strata are faulted against the underlying volcanic series, as along the southern slope of the Campsie Fells. The Hurlet limestone is the lowest limestone of the series, and is one of the most persistent bands. In the Carluke district the lowest group contains from twelve to fifteen beds of limestone, but the two best known seams in it are the Hurlet and the Hosie limestones. The middle group contains several workable coal-seams, of which the Lesmahagow gas-coal is one of the important seams, and in the lower portion of this group there are valuable bands of ironstone. The upper group comprises three beds of limestone, the lowest being the Index--so named because it overlies the valuable coal-bearing subdivision of the Carboniferous Limestone, the middle being the Calmy, and the upper the Gair or Castlecary band. The same subdivisions are represented in the Ayrshire field, with this important modification, that the lowest or Hurlet limestone has an exceptional development near Beith, where it is about 100 feet thick, and is richly charged with marine organisms. In the northern parts of the same basin, at Dairy, evidence has been obtained of the existence of buried volcanoes, filled with tuff, which Sir A. Geikie assigns to the period of puy-eruptions that followed the volcanic phase of the Calciferous Sandstone period. He states that in one pit upwards of 115 fathoms of tuff were passed through before the position of the blackband ironstone in that portion of the field was reached by driving levels through the tuff into the adjoining strata. The tuff occurs in patches between which the blackband ironstone is workable. ...
