I.—On the Distribution beyond the Tertiary Districts of White Clays and Sands subjacent to the Boulder-clay Drifts

Published online by Cambridge University Press:  01 May 2009

Extract

The object of the following paper is to record some further observations on the distribution in North Wales of deposits of White Clays and Sands older than the Boulder-clay and its accompanying gravel drifts, similar to those in the neighbourhood of Llandudno, described in the Geological Magazine of May, 1865, and also to give a condensed summary of what records I have been able to collect of the occurrence of similar deposits in other parts of the kingdom.
