In the second section, I furnish a more technical and detailed appraisal of the each of the twelve chapters with comments about those major publications previously regarded by archaeologists as key sources on these specific topics.Lastly, there is a conclusion that incorporates a general discussion about this volume and its relationship to similar works and the current status of chronometric or "time placement" dating.The footprints weave intricate paths across the desolate landscape.Some tracks race straight toward an unseen finish line; others meander, the outlines of their ancient owners' toes and curves of their arches carved deeply into the sun-baked earth.The combination of imaging techniques facilitates observation and interpretation of the rocks’ microscale features.

To discover if mass transfer was accomodated by microcracks during deformation, X-ray element mapping was also employed.

The book may certainly be regarded as a highly technical compendium, an essential reference work that should be acquired by any library and is mandatory for advanced students, and practitioners.

This is, however, also a significant document--a status report--which synthesizes the latest thinking about important dating methods written by a distinguished assemblage of international experts. Initially, I provide a broad assessment that will establish a background and a context for chronology in archaeology, and I shall present an overall evaluation of the volume.

The air shimmers with heat, and the active volcano that locals call "the mountain of God" looms in the middle distance.

It's not difficult for geologist Cynthia Liutkus-Pierce to imagine this scene as it would have looked thousands of years ago, when prehistoric people walked across the muddy terrain and left an indelible record of their presence pressed into the ground.
