Book excerpt: Events across the Precambrian-Cambrian boundary brought about the most dramatic geological change in Earth's history: the appearance of invertebrates, including animals with hard parts, that began the Phanerozoic fossil record. This book provides an up-to-date review of the "Precambrian-Cambrian boundary problem" as seen by a group of experts active in this controversial area of research. For more than a decade, international groups have been unearthing new information about the sequence of events during this period, centered around the question of where to fix the actual boundary point. Using a chronological framework, the book gathers together information essential to the understanding of the evolutionary extinctions and events that brought the Precambrian period to an end.

Download or read book Lithology Trace Fossils and Correlation of Precambrian Cambrian Boundary Beds Cassiar Mountains North Central British Columbia written by William Harold Fritz and published by Geological Survey of Canada. This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace fossils from the upper part of the Stelkuz formation (609m +) and from the overlying Boya Formation (400.5 m) permit atentative definition of the Precambrian-Cambrian boundary in theCassiar Mountains. The strata investigated are below the top ofthe Lower Cambrian Fallotaspis Zone, a level located 1.5 m abovethe upper contact of the Boya Formation. The Precambrian-Cambrian boundary is tentatively placed 592 m below this level ata disconformity within the Stelkuz Formation. Correlations withother boundary strata in the Canadian Cordillera suggest theoptimum area for further testing ichnofossil ranges is in theMackenzie Mountains. Intercontinental correlations are alsoattempted.

Download or read book The Geologic Time Scale 2012 written by F M Gradstein and published by Elsevier. This book was released on 2012-08-14 with total page 1176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)
