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

Geochemistry, 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.

Chemostratigraphy of the Pliensbachian, Puesto Araya Formation (Neuquén Basin, Argentina) [PDF]

Geologica Acta, 2005
In a preliminary attempt to establish an isotope stratigraphy, strontium, carbon and oxygen isotope ratios were determined from marine biogenic carbonates of Pliensbachian age, in the context of scheme of local ammonite Zones correlatable to the European

Chemostratigraphy of the extrusive sequence of a Late Cretaceous Neotethyan ophiolite in Southern Iran and its significance for the mode and tempo of subduction initiation magmatism and melt evolution in forearc tectonic settings

Journal of the Geological Society, 2023
Chemostratigraphy of lavas in extrusive sequences of the modern and ancient forearc environments provides significant information on oceanic crust formation through progressive stages of melt evolution from subduction initiation magmatism (SIM) to arc ...

An integrative biostratigraphic, chemostratigraphic, and sequence stratigraphic perspective of the Ordovician–Silurian boundary on Anticosti Island (Canada) [PDF]

Estonian Journal of Earth Sciences, 2023
Anticosti Island, Canada, has long been recognized as an exceptional Ordovician–Silurian boundary succession with the potential to serve as one of the best records of climatic, oceanographic, and biological events associated with the Late Ordovician ...

Late Cenomanian-Turonian isotopic stratigraphy in the chalk of the Paris Basin (France): a reference section between the Tethyan and Boreal realms

BSGF - Earth Sciences Bulletin, 2021
A chemostratigraphic study (δ13C and δ18O) of the Late Cenomanian and Turonian chalk succession from the “Craie 701” Poigny borehole (near Provins in the Paris Basin, France) provides new high-resolution stable carbon and oxygen isotope data. Correlation

Stratigraphy and facies differences of the Middle Darriwilian Isotopic Carbon Excursion (MDICE) in Baltoscandia [PDF]

Estonian Journal of Earth Sciences, 2020
The Middle Darriwilian Isotopic Carbon Excursion (MDICE) is a global isotopic event described in sections from different palaeocontinents. Here we present new stable carbon isotopic data from carbonates of ten sections in different parts of the ...
