There has long been a strong collaboration between geologists and archaeologists, and the sub-field of geoarchaeology is well developed as a discipline in its own right. This book now bridges the gap between those fields and the geophysical technique of ground-penetrating radar (GPR), which allows for three-dimensional analysis of the ground to visualize both geological and archaeological materials. This method has the ability to produce images of the ground that display complex packages of materials, and allows researchers to integrate sedimentary units, soils and associated archaeological features in ways not possible using standard excavation techniques. The ability of GPR to visualize all these buried units can help archaeologists place ancient people within the landscapes and environments of their time, and understand their burial and preservation phenomena in three-dimensions.
Readership: Advanced students in archaeology and geoarchaeology, as well as practicing archaeologists with an interest in GPS techniques.

A propos de l’auteur
Lawrence B. Conyers is Professor of Anthropology at the University of Denver, Colorado, USA. Holding degrees in both geology and anthropology, with a focus on archaeology, his field experience has taken him around the world on hundreds of projects, many of which are used as examples in this book. He is the author of four previous books on the ground-penetrating radar method and its interpretation.
