Geochemical records and environmental analysis of the Ediacaran-Cambrian boundary in Eastern Yunnan, South China

open access: yesFrontiers in Earth Science, 2023
The Ediacaran–Cambrian transition is characterized by an unprecedented change in biosphere, lithosphere, and atmosphere. However, the identification of this transition and its global correlation remains debated.

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

New Geochronological Age Constraint and Chemostratigraphy for Aptian Lacustrine Strata, Cedar Mountain Formation, Utah

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The Early Cretaceous is an important time of transition in Earth history, marked by a succession of oceanic anoxic events and carbon cycle perturbations that drove changes on land and in the ocean.

ASSESSING MUDROCK CHARACTERISTICS, HIGH-RESOLUTION CHEMOSTRATIGRAPHY, AND SEQUENCE STRATIGRAPHY OF THE WOODFORD SHALE IN THE MCALISTER CEMETERY QUARRY, ARDMORE BASIN, OKLAHOMA [PDF]

open access: yes, 2017
The Late Devonian – Early Mississippian Woodford Shale is a significant unconventional play in the Midcontinent region. An approximately 365ft thick exposure of the Woodford Shale is present in the McAlister Cemetery Quarry.

Local and Global Controls on Carbon Isotope Chemostratigraphy

open access: yes, 2022
Over million-year timescales, the geologic cycling of carbon controls long-term climate and the oxidation of Earth's surface. Inferences about the carbon cycle can be made from time series of carbon isotopic ratios measured from sedimentary rocks. The foundational assumption for carbon isotope chemostratigraphy is that carbon isotope values reflect ...

Chemostratigraphic implications of spatial variation in the Paleocene‐Eocene Thermal Maximum carbon isotope excursion, SE Bighorn Basin, Wyoming

open access: yesGeochemistry, Geophysics, Geosystems, 2013
The Paleocene‐Eocene Thermal Maximum (PETM) is marked by a prominent negative carbon isotope excursion (CIE) of 3–5‰ that has a characteristic rapid onset, stable body, and recovery to near pre‐CIE isotopic composition.
