Abstract

The Cambrian Series 2–Series 3 boundary intervals of five mixed carbonate–siliciclastic successions of Gondwana, Laurentia, and Siberia were analysed for their carbonate carbon isotopes (δ13Ccarb) and sulphur isotopes from carbonate-associated sulphate (δ34SCAS). For all sections, the boundary interval is characterized by distinct positive δ13Ccarb excursions, flanking the first appearance datum (FAD) of trilobite species applied for the definition of (regional) bases of Cambrian Series 3. Whether the positive δ13Ccarb shifts could be used as an additional proxy for an intercontinental correlation of the base of Cambrian Series 3 needs to be evaluated. No distinct positive and/or negative δ34SCAS excursions are discernible for the investigated successions. However, δ34SCAS data provide important information for the characterization of palaeoenvironmental conditions, but probably give no additional detail for a global correlation of the Cambrian Series 2–Series 3 boundary interval.
