neodymium isotopic equilibrium may occur between authigenic clay minerals,
ambient waters, source rocks and petroleum.
We have benefited from many discussions with, and helpful comments from,
several of our colleagues and friends. Peter Stille would like to express his
gratitude to Emilie Jtiger (Bern) and Mitsunobu Tatsumoto (Denver) who were
undoubtedly the greatest influences during his formative years in science. Thanks
go to Norbert Clauer (Strasbourg) for first introducing Peter Stille to sediments.
We are also grateful to Franqois Gauthier-Lafaye, Regis Bros. Marc Steinmann,
Miriam Andres, Urs Schaltegger, Horst Zwingmann and Jost Eikenberg. Especial
thanks go to Claude Hammel who drafted all the figures.
