“ The central district has only one, but that is the largest and best marked of all, namely, the Dudley Port Trough, which runs nearly north-north-east for three miles, and then gradually curving round seems to merge into the system of east and west faults that traverse that portion of the coal-field.
The Great Bentley fault is itself the southern side of a trough, though of an unequal and imperfect character, since the amount of the upthrow of the corresponding fault on the northern side is only about one-fifth or one-sixth of the downthrow of the Great Bentley fault itself. ”

“ The South Staffordshire coal-field seems like an island of Palæzoic rocks rising up through the secondary New red sandstone plain of the centre of England. These rocks appear at the surface partly in consequence of their being elevated to a higher level than the Palæzoic rocks immediately adjacent to them, which are still covered by the New red sandstone, and partly in consequence of the New red sandstone, which once covered them also, having been removed by denudation. ”

“ All faults and all strikes that do not coincide very closely with one of those four lines of bearing are either small and unimportant, or occupy spaces that may be described as merely the connecting links where the one line of bearing is passing into the other. ”
