Paleoclimate Implications from Stable Isotope Analysis of Sedimentary Organic Carbon and Vertebrate Fossils from the Cedar Mountain Formation, UT, U.S.A.
<p>Oxygen and carbon isotopic compositions of fossilized vertebrate teeth and bone were analyzed to determine isotopic values of vertebrate faunal diet from the early Cretaceous Cedar Mountain Formation of Utah. Results for δ18O of PO4 (δ18Op) (Suarez et al., 2014) from the same data set have been …

An organic geochemical approach to problems of glacial-interglacial climatic variability
The concentration and carbon isotopic composition (δ13C) of sedimentary organic carbon (Corg), N/C ratios, and terrigenous and marine δ13C-Corg end-members form a basis from which to address problems of Late Quaternary glacial-interglacial climatic variability in a 208.7 m hydraulic piston core …

Carbonate Carbon Isotope Chemostratigraphy from the Ruby Ranch Member of the Cedar Mountain Formation in the Western San Rafael Swell
… gray silty-sandy mudstones with abundant carbonate nodules suggestive of paleosol development. For this study samples were collected approximately every 25 cm and were used to construct a C-isotope curve using carbonate carbon. These were used to compare to existing bulk sedimentary …
