The authigenic clay mineral assemblage of paleosol profiles and trends in their bulk geochemical evolution provide insight into the intensity of past chemical weathering regimes. These climate-sensitive weathering products can be used to interpret re

This work addresses the potential utility of in situ carbon and oxygen isotope microanalysis (δ13C and δ18O) by secondary ion mass spectrometry (SIMS) in carbon sequestration research. A desirable long-term consequence of CO2-injection into undergr

We developed a simple method of analyzing the strontium (Sr) and calcium (Ca) content of intact eggshell samples in support of a broader study of how dietary Sr uptake impacts waterfowl eggshell quality. We used wavelength dispersive - x-ray fluoresc

Oxygen isotope (δ18O) zonation in carbonate mineral cements is often employed as a proxy record (typically with millimeter-scale resolution) of changing temperature regimes during different stages of sediment diagenesis. Recent advances in secondary

Carbon stable isotope data (δ13C) and new radiometric dates indicate that the non-marine Late Cretaceous lower Cantwell Formation, central Alaska, registers the Middle-Maastrichtian Event (MME), a global warming episode. A stratigraphic section meas

We document the development of a suite of carbonate mineral reference materials for calibrating SIMS determinations of δ18O in samples with compositions along the dolomite–ankerite solid solution series [CaMg(CO3)2–CaFe(CO3)2]. Under routine ope

We investigate the Late Devonian Frasnian- Famennian extinction interval in western Alberta and south China to shed light on the palaeoecological and palaeoceanographic conditions that characterize this biotic crisis. Both the Lower and Upper Kellwas

The Miocene of the northern part of the Polish Carpathian Foredeep contains a record of events particularly important in the evolution of the Central Paratethys Basin. There, the Paratethyan Badenian Salinity Crisis resulted in the deposition of evap
