A geologic time scale
"This reference book is a concentrated review of the time scales used in geology in order to date stratigraphic sequences and to define the geologic epochs. The text presents, discusses and evaluates the state of chronostratigraphic, chronometric and other scales; this includes a revised calibration in years of the standard stratigraphic scale. There are chapters with (1) introductory and historical background, (2) stratigraphic time scale and correlation charts for each period or other time interval with commentaries, (3) a new way of presenting the data for age estimates of each boundary (chronograms) which attempts to depict the strengths and weaknesses of the calibration, (4) a new magnetostratigraphic time scale and (5) a summary of world events in the form of charts. This book with its profusion of tables and data will serve as a fundamental reference source in the Earth Sciences."--Additional title page
