Chemostratigraphy in southern Ontario by pXRF spectrometry

open access: yes, 2017
For groundwater studies, the collection of sediment geochemistry is often beyond the scope, and budget of many programs, and is generally not included as part of routine data collection. Portable x-ray fluorescence spectrometer (pXRF) has proven to be a successful tool to characterize the chemostratigraphy of glacial derived materials collected from ...

Ocean acidification in the aftermath of the Marinoan glaciation [PDF]

open access: yes, 2014
Boron isotope patterns preserved in cap carbonates deposited in the aftermath of the younger Cryogenian (Marinoan, ca. 635 Ma) glaciation confirm a temporary ocean acidification event on the continental margin of the southern Congo craton, Namibia.

Quantitative and Nuanced Approaches Elucidate Carbon Isotope Records

open access: yesGeochemistry, Geophysics, Geosystems
Earth scientists have leveraged carbon isotope records to interpret Earth history and establish chronostratigraphic frameworks for decades (e.g., Halverson et al., 2005, https://doi.org/10.1130/b25630.1; Kaufman & Knoll, 1995, https://doi.org/10.1016 ...
