Neodymium Isotope Ratios and a Positive δ13C Excursion: Connecting Oceanographic and Climate Changes Near the M4-M5 Sequence Boundary of the Late Ordovician
A significant positive carbon isotope excursion first described from the Guttenberg Member of the Decorah Formation in Iowa called the GICE is a defining feature of Late Ordovician chemostratigraphy. It occurs near the M4-M5 sequence boundary of the Late Ordovician and has been correlated across the...
