The White Stone Band of the Kimmeridge Clay Formation, an integrated high resolution approach to understanding environmental change

, 2004
The Kimmeridge Clay is a Jurassic mudrock succession that shows Milankovitch Band climatic cyclicity. A key issue is to determine how the subtle changes that define this cyclicity result from climatic change.
