This book gives a new global perspective to the Phanerozoic timescale, by bringing together extensive Australian and overseas research on biostratigraphy, geochronology and magnetostratigraphy. For the first time, correlations are established between Australian and European biozonal schemesfor the entire Phanerozoic, by integrating local and international biozones, isotopic ages, and magnetic polarity intervals. The compilation relies on tie points using tightly constrained isotopic and biostratigraphic ages. It is the first Phanerozoic scale whose time calibration is heavilyweighted by modern application of isotopic dating of the 1980s and 1990s, especially variants of 40 Ar/39Ar and U/Pb zircon-dating, which have radically rescaled some parts of geologic time. An Australian Phanerozoic Timescale gives the essential framework for resource exploration, geologicmodelling, and reconstruction of past environments and land-sea configurations during the last 545 million years of earth history. The book comes with 12 extended charts (size 650 x 190 mm) boxed together.
