Hydrogeology of Crystalline Rocks deals with deep groundwater in the
granite and gneiss basement of the continents. It has become evident
during the past years that highly mineralized water is present in an
interconnected fracture network of the basement. Thus, the upper part of
the crust of the continents can be viewed as an aquifer and investigated
with tools common in hydrogeology.
This book presents accounts on water-conducting features of crystalline
rocks and summarizes the hydraulic properties of the basement. The
volume includes reviews, new data and research on the often remarkable
chemical composition of deep groundwater. Microbial processes in the
deep basement aquifer are probably more important than previously
thought. Two contributions focus on this recent extension of research of
the biosphere to greater depth in the Earth.
This book represents the first multidisciplinary and integrated account
of deep groundwater hydrology in crystalline basement. It is of interest
to hydrologists and hydrogeologists working with water in crystalline
rocks, but also to solid earth geophysicists, geochemists and
petrologists with an interest in fluids in the crust. Scientists
involved in nuclear waste disposal programs and geothermal energy
development will find a wealth of stimulating ideas in this volume.
