On the Tectonics of the Southern Midlands

In any purely stratigraphical treatment of a tectonic problem one of the greatest of the initial difficulties is always that of deciding where to begin, and in the present case this difficulty is unusually acute, since the primary object of the investigation is an endeavour to trace back phenomena occurring in later ages to causes of long antecedent origin. In more precise language, the object aimed at is to show that certain structural features of the Mesozoic rocks of the southern Midlands of England can be attributed to the recurrence of activity along old-established fold-lines of very early date.
