For more than fifty years, small numbers of scientists have been concerned with the interrelationships of Earth and life. Over the past decade, however, geobiology has emerged as an exciting and rapidly expanding field. This book sets out a coherent set of principles that underpin geobiology, and will act as afoundational text that will speed the intellectual dissemination of those principles. The book is of interest to advanced undergraduates and graduates in the earth and biological sciences, and to the growing number of scientists worldwide who have an interest in the burgeoning discipline of Geobiology. INDICE : 1. Introduction. General introduction to the emerging field of geobiology, including an explanation of the books major segments (process, toolsand applications, historical geobiology), and a geobiological phylogeny of life -- much like the geological periodic table published recently.GeobiologicalProcesses:.2.
