The measurement of isotope ratios in sedimentary rocks deposited over geological time can
provide key insights to past environmental change over important intervals in the past …

We report a geochemical study of a composite sedimentary section that captures the
Permian–Triassic (PT) transition at Kap Stosch, East Greenland. The samples were from the …

The plant fossil record from Lower Triassic sedimentary successions of the Western USA is
extremely meager. In this study, samples from a drill core taken near Georgetown, Idaho …

In the aftermath of the catastrophic end-Permian mass extinction, the Early Triassic records
recurrent perturbations in the carbon isotope signal, most notably during the Smithian and …

Carbon isotope records for inorganic and total organic carbon (TOC) as well as for individual
organic biomarkers show two positive excursions in the Late Frasnian with comparable …

A major late Paleozoic depocentre, the Sverdrup Basin, Canadian High Arctic, has been
largely left out of the latest Permian extinction debate, as early workers presumed Middle to …

Eoarchean peridotite enclaves found in southern West Greenland's Itsaq Gneiss Complex
(IGC) represent an important and valuable record of Earth's early geodynamic history …

Abstract The ca. 810 Ma Bitter Springs carbon isotope anomaly is an abrupt and long-lived
(5–10 Myr.) departure from the positive carbon isotope values (δ 13 C carb) that otherwise …

The large isotopic fractionation of carbon associated with enzymatic carbon assimilation
allows evidence for life's antiquity, and potentially the early operation of several extant …

Carbon stable isotopes from carbonate minerals (mainly dolomite) from six wells from the
Lower Triassic Sherwood Sandstones of the Corrib Gas Field, Slyne Basin, west of Ireland …
