Diluvium Sentence Examples
The bottom is in many parts the diluvium of lakes drained by the rivers.
But the most important technical use of the word is in geology, as introduced by C. Lyell in 1840 in place of " Diluvium."
The earlier geologists had been in the habit of dividing the Quaternary deposits into an older Diluvium and a younger Alluvium; the latter is still employed in England, but the former has dropped out of use, though it is still retained by some continental writers.
The Alluvium was distinguished from Diluvium by the fact that its mammalian fossils were representatives of still living forms, but it is a matter of great difficulty to separate these two divisions in practice.
