A comprehensive Cambrian correlation chart

Abstract

The International Subcommission on Cambrian Stratigraphy has introduced a number of internal subdivisions (i.e., series and stages), but most of the explanatory publications lack reliable data on the correlation between all Cambrian key continents. A comprehensive correlation chart is presented here to review and document correlatable biostratigraphic horizons within the system and correlation of biostratigraphic zones and regional series and stages, accompanied by explanatory remarks. The chart also presents important available non-biological correlation data, such as carbon isotope signatures and radiometric ages.
