Pore-water extraction from argillaceous rocks for geochemical characterisation: methods and interpretations

This work reports the results of a comprehensive
critical review, initiated by the OECD/NEA “Clay
Club,” of the extraction techniques available to obtain water,
and solutes from argillaceous rocks. The book focuses
on the mechanisms involved in the extraction processes,
the consequences on the isotopic and chemical composition
of the extracted pore water and the attempts made to
reconstruct its original composition. Finally, it provides
some examples of reliable techniques and information, as
a function of the purpose of the geochemical study.
