VI.—The Upper Trias of Leicestershire

Published online by Cambridge University Press:  01 May 2009

Extract

A study of the local stratigraphy, tectonics, petrography, and palæontology leads to some conclusions as to the physiography of the epoch in this district. Even studied as a detached area it may be noticed that the Bunter or pebble deposits are west of the sandstones and marls. From the fact that the eastern limits of the first two are west of the marls, and the second (sandstones) west of the pebbles, and from the evidence of other areas, it appears that this purely local west to east succession is applicable to the whole British area, and it is well known that each member thins from north-west to south-east (as a whole). This is the sequence typical of aqueous deposits, and particularly of delta deposits, and at the same time indicates (in part) the direction from which the sediment came.
