The book is global in scope and discusses the data on early Earth from sites in southwest Greenland, Canada, Australia, India, South Africa, and more. ... The volume is well supported by numerous tables, color photographs, color and black-and white illustrations, appendixes, an extensive 30-page list of references, and a 13-page subject/geographic index. Summing Up: Recommended. Graduate students, researchers/faculty, and professionals/practitioners. The author provides an extensive overview of the geochronological data pertaining to the Archean, and integrates this with geochemical and isotopic information. ... The author has done a commendable job of compiling a mountain of geochronological and isotopic data, much of which is helpfully collated into an Appendix. ... The book will be useful for research-oriented workers dealing with Archean rocks.
