Origin and Mineralogy of Clays, the first of two volumes, lays the groundwork for a thorough study of clays in the environment. The second volume will deal with environmental interaction. Going from soils to sediments to diagenesis and hydrothermal alteration, the book covers the whole spectrum of clays. The chapters on surface environments are of great relevance in regard to environmental problems in soils, rivers and lake-ocean situations, showing the greatest interaction between living species and the chemicals in their habitat. The book is of interest to scientists and students working on environmental issues.

This book represents a rather complicated history of encounters, changes in research interest and some very interesting results. Initially it is the very fruitful interaction of Ecology and Geology. The point of view of ecologists is extremely refreshing for hard science people. Interaction and inter-relationships are the focus of Ecology whereas the traditional sciences, such as Geology, have tried to isolate the natural phenomena so that thye could be studied in a more rigorous manner. The traditional sciences were of course natural science – based since the world to be observed was at the door step of everyone, mountains, weather patterns, plants and so forth. Chemistry and Physics were de ned after Mathematics in order to establish more precise and viable principles of the behavior of the materials that formed the world around mankind. It became quite clear that the observation of the natural world was too complicated to consider all of the possible variables which could affect an observed process or situation. The systems were simpli ed and taken into the laboratory in order to better master the phenomena observed. Physics c- cerned itself with non-reacting materials, subjected to essentially mechanical forces.

Of course such a book as we propose here is not the product of just two people working together, although the experience has been a great pleasure for us. We would like to thank our many collaborators and students who have encouraged our effort by their, often, sharp criticism. We hope that we have used their comments to good effect. Es- cially we would like to thank Pierre Barré for his help, enthusiasm and consent for the use of much of his thesis material in formulating the last chapter of the book. Dominique Righi was instrumental in giving us ideas, useful comments and vigorous debate for a great number of our ideas and during the periods of formulation of our conclusions. Our approach is from mineral chemistry and hence has greatly benefited from disc- sions with people who know soils and plants. The project of this book was realized and encouraged with the help of Wolfgang Engel who, unfortunately is not with us to see its finalization. We greatly regret his passing. This book is not in the general pattern of accepted knowledge and analysis of the phenomena which affect the occurrence of clays in the surface environment. We stress the role of plants at the bio-interface and the importance of microsystems at the water/ rock interface. We believe that the literature at our and anyone’s disposal shows that the system of clay formation and reaction is highly dynamic, especially at the surface.

Geochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc.) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.

The text which follows is based largely on the personal experience of the authors. The examples used which concern archaeological material, thin sections of sherds and many of the case studies are for the most part those which we have developed ourselves. This experience. may seem biased when one thinks of the large experience of petrographic archaeology, and this is surely true, but it is a reflection of our observations which are more complete for the objectives we have in mind than most of the examples given in the literature. For example, we have access to initial sherds, photo graphs, grain-size measurements and so forth for the same materials and we can present a specific archaeological context and problem using these data. Of course, there have been many studies on the same general subjects published elsewhere. As it turns out, our collective experience covers two of the major fields of investigation, the old (European) world and the new (American) one. It is evident that the problems are different in these two worlds. The contexts of production, distribution and use are different. The evolution of tech niques is very different although covering similar time periods. These two view points are complementary and, we hope, will enrich the investigative methods and outlook of workers in both cultural areas.

This book introduces students in archaeology and others interested to the materials that form ancient ceramics. It focuses on the nature of these materials, the minerals, rocks, clays, and ways they have been modified for the production of ceramics. The study of the use of the ceramic materials by potters through the ages allows us a better understanding of the potter's behavior and the influences on his or her craft. The book details clay, mineral and rock formations, basic geology principles, types of analyses conducted to study raw materials, and the different processes involved in making pottery. It describes the different attributes of a ceramic paste, and the different scales one can look at it. This book is conceived as an introduction to the origin of the materials which form ceramics in an archaeological context, their selection and use by potters.
