Slope clay-with-flints (biefs à silex) as indicators of Quaternary periglacial dynamics in the western part of the Paris Basin, France

The lithology and distribution of the clay‐with‐flints occurring on slopes, called biefs à silex in French, suggests a twofold classification of these deposits according to slope angle. Biefs à silex formed as a solifluction deposit under Quaternary periglacial conditions during valley development....

Zusammenfassung:	The lithology and distribution of the clay‐with‐flints occurring on slopes, called biefs à silex in French, suggests a twofold classification of these deposits according to slope angle. Biefs à silex formed as a solifluction deposit under Quaternary periglacial conditions during valley development. Two biefs à silex facies suggest two phases of development between 800 000 and 20 000 yr BP. Copyright © 2003 John Wiley & Sons, Ltd.
