Geomicrobiology of Río Tinto: A Terrestrial Mars Analogue provides the most detailed biological and geological characterizations of one of Earth's best terrestrial Mars analogues. The acidic waters of Río Tinto and the high metal content of its sediments have given rise to a unique biodiversity. Understanding the geochemical and mineralogical conditions that have shaped the evolution of these extremophiles is essential to guiding the selection of sites for meaningful missions to Mars. Edited by a renowned astrobiologist with contributions from global experts with applied experience in Mars exploration missions, this book is systematically structured for a wide audience. Sections delve into the physical characteristics and biological diversity of Río Tinto, its suitability as a terrestrial Mars analogue, and the fundamentals and applications of geomicrobiology. Geomicrobiology of Río Tinto: A Terrestrial Mars Analogue provides its interdisciplinary audiences with the fundamentals to understand the paleontological record of the system, the diversity existing in its water column, the biological activities responsible for its extreme conditions, and their biotechnological applications and relevance to future exploration missions to the red planet. This is an essential read for astrobiologists, aquatic biologists, geomicrobiologists, paleontologists, and biotechnologists alike.
