The geologic time scale / Геологическая временная шкала
This study presents the science community and schools with a new geologic timescale for circa four billion years of Earth history. A chapter is also devoted to time scales for our moon and neighboring planets. This book details many recent advances in stratigraphy, the science of the layering of strata and its content, in radiogenic and stable isotopes chronology, and in age and duration calculations using orbital tuning models. The new scale closely links radiometrically and orbitally tuned age dates, and tries to provide comprehensive error analysis on the ages of a majority of boundaries for the geologic divisions of time. Much benefit is derived from the steady increase in formal definition of stage boundaries such that we have more stability in geologic unit definition than in 2004. This book thus presents Geologic Time Scale 2012 (GTS2012, as the successor of GTS2004) <...>
