The Hirnantian carbon isotopic excursion (HICE) was characterized by a positive δ 13 C
excursion (up to~+ 7‰) of oceanic dissolved inorganic carbon (DIC). However its …

Mudrocks are a primary archive of Earth's history from the Archean eon to recent times, and
their source-to-sink production and deposition play a central role in long-term ocean …

Recurrent mass extinction events (at “biomere”—a biostratigraphic unit—boundaries)
characterize the middle Cambrian to Early Ordovician (Tremadocian) time interval that is …

The carbon isotopic (δ13C) composition of shallow-water carbonates often is interpreted to
reflect the δ13C of the global ocean and is used as a proxy for changes in the global carbon …

We present a suite of major element stable isotope (δ 13 C, δ 18 O, δ 44/40 Ca, δ 26 Mg),
and selected trace element (Sr/Ca and Mg/Ca) data from Pleistocene sediments from the …

Abstract The Middle Ordovician Darriwilian Stage (∼ 469–458 Ma) records a∼ 2‰ positive
carbon isotope shift known as the MDICE (Mid-Darriwilian Carbon Isotope Excursion) …

Abstract The Ordovician and Silurian periods were times of major geological activity as
regards palaeogeography, volcanism and climate change, the last of these evidenced by a …

The organic-rich black shales from the Late Ordovician and early Silurian were identified as
essential source rocks for shale gas exploration and development in South China. To …

The clumped isotope temperature proxy has been used to investigate the diagenetic history
of carbonate sediments in two cores recovered during ODP Leg 166 on the margin of Great …

Integrated analysis of sedimentological, stratigraphic, paleontological, and
chemostratigraphic data of the Ordovician–Silurian Pin Formation exposed in the Parahio …
