Journal ArticleDOI
Geochemical evidence for widespread euxinia in the Later Cambrian ocean
Benjamin C. Gill,Timothy W. Lyons,Seth A. Young,Lee R. Kump,Andrew H. Knoll,Matthew R. Saltzman +5 more
TL;DR: The SPICE interval is identified as the best characterized ocean anoxic event in the pre-Mesozoic ocean and an extreme example of oxygen deficiency in the later Cambrian ocean, indicating the environmental challenges presented by widespread anoxia may have been a prevalent if not dominant influence on animal evolution in Cambrian oceans.
Journal ArticleDOI
Long-lived glaciation in the Late Ordovician? Isotopic and sequence-stratigraphic evidence from western Laurentia
TL;DR: In this article, an integrated δ13C and sequence stratigraphic analysis in Nevada is presented, showing that in the Late Ordovician Chatfieldian Stage (mid-Caradoc) a positive δ 13C excursion in the upper part of the Copenhagen Formation was closely followed by a regressive event evidenced within the prominent Eureka Quartzite.
Book ChapterDOI
Chapter 11 – Carbon Isotope Stratigraphy
Matthew R. Saltzman,Ellen Thomas +1 more
TL;DR: In this article, a review of carbon isotope variations through geologic time compiled from multiple literature sources is presented, where the authors consider whether skeletal carbonate secreted by specific organisms or bulk carbonate has been used in evaluating or comparing carbon isotopes stratigraphic records.
Journal ArticleDOI
Phosphorus, nitrogen, and the redox evolution of the Paleozoic oceans
TL;DR: In this paper, a high-resolution d 13 Ccarb curve from the Great Basin was used to study the transition between the highly unsettled Neoproterozoic and the increasingly stable Mesozoic to Cenozoic periods.
Journal ArticleDOI
A global carbon isotope excursion (SPICE) during the Late Cambrian: relation to trilobite extinctions, organic-matter burial and sea level
Matthew R. Saltzman,Robert L. Ripperdan,Martin D. Brasier,Kyger C. Lohmann,Richard A. Robison,W.T. Chang,Shanchi Peng,E.K. Ergaliev,Bruce Runnegar +8 more
TL;DR: The Steptoean positive carbon isotope excursion (SPICE) as discussed by the authors is a global oceanographic event that confirms intercontinental correlations between different biogeographic realms based on agnostids and other blue-water trilobites.
