Seawater 87Sr/86Sr Stratigraphy of the Middle Ordovician in Central Virginia [PDF]
, 2017 Throughout most of the past century, the correlation of strata in a region has mainly been defined through biostratigraphy, the dating of rock through fossil succession.

Sedimentology, Volume 72, Issue 4, Page 1316-1342, June 2025.ABSTRACT Establishing depositional environments in ancient mudstone successions from epeiric seas is difficult due to the lack of obvious lithological changes, leaving long, largely undifferentiated mudstone intervals that complicate their correlation to near‐shore environments.

The Case for the Anthropocene Epoch Is Stronger Than the Case for the Holocene Epoch
Earth's Future, Volume 13, Issue 5, May 2025.Abstract The recommendation that the Anthropocene be denoted as a geological epoch was recently rejected by the International Union of Geological Sciences. Here, we compare the scientific rationales presented for the Anthropocene, the Holocene and the six other epochs in the Cenozoic Era: the Pleistocene, the Pliocene, the Miocene, the Oligocene, the ...

Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]
, 2005 Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...

High-precision tephrostratigraphy : tracking the time-varying eruption pulse of Mt. Taranaki, North Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Earth Science, Massey University, Palmerston North, New Zealand [PDF]
, 2017 In this research it was proposed that a more robust record of volcanic activity for Mt. Taranaki (New Zealand) could be derived from tephras (pyroclastic fall deposits) within cores from several lakes and peatlands across a 120o arc, NE-SE of the ...

Anomalous negative excursion of carbon isotope in organic carbon after the last Paleoproterozoic glaciation in North America [PDF]
, 2010 Early Paleoproterozoic time (2.5–2.0 Ga) spanned a critical phase in Earth's history, characterized by repeated glaciations and an increase in atmospheric oxygen (the Great Oxidation Event (GOE)).

Subsidence history of the Ediacaran Johnnie Formation and related strata of southwest Laurentia: Implications for the age and duration of the Shuram isotopic excursion and animal evolution [PDF]
, 2018 The Johnnie Formation and associated Ediacaran strata in southwest Laurentia are ~3000 m thick, with a Marinoan cap carbonate sequence at the bottom, and a transition from Ediacaran to Cambrian fauna at the top.
