Summary

A recent excavation at Newtown Unthank, 9 km west of Leicester, has permitted study of the sub-alluvial gravels of the Rothley Brook valley. The junction of the gravels with the underlying Keuper Marl is sharply contorted, with an upward progression from undisturbed bedrock, through displaced marl and siltstone layers into masses of marl which have apparently been thrust up into the overlying gravel and incorporate many foreign stones. Possible causes of the structures are outlined, and reasons adduced for believing them to be of periglacial origin and of Weichselian age. Comparable occurrences have been recorded from elsewhere in the Soar basin, and also from other parts of the Midlands, and these are briefly discussed.
