Provides comprehensive coverage of all aspects of clay seals, from the formation of deposits and an analysis of their composition and properties, to the physical relationships between these clay seals and the environments in which they are found. Looks at seven different types of clay seals from a number of sites, highlighting important properties and methods of analysis used to distinguish and classify clay seals.
The final part of the book deals with modelling the state and properties of clay seals occurring at various depths, showing variations in porosity and strength at different lithogenesis stages. Additionally, the authors consider the possibility of predicting screening properties of clay seals using computer programs.
