ORGANIC GEOCHEMICAL ASSESSMENT AND SHALE GAS POTENTIAL OF LOWER SILURIAN ORGANIC RICH SHALE IN THE GHADAMES BASIN, NORTH AFRICA; pp. 337–352 [PDF]

open access: yesOil Shale, 2019
The Silurian organic rich shale is the main source of hydrocarbons in the Ghadames Basin in North Africa. The basin has been widely characterized as a source rock for Ordovician oil and gas; yet understanding this shale as a shale resource play remains ...

Chemostratigraphy of the Snorry Drift in the North Atlantic

open access: yesOceanology, 2019
On the basis of multi-element chemical analysis and oxygen isotopic data, for the first time the distribution of some geochemical indicators was investigated in the sediment core taken at the Western slope of the Snorry contourite drift (St. AI-3378, North Atlantic) in the 49th cruise of RV "Akademik Ioffe" in 2015. Down the core an asynchronous change

Aras Valley (northwest Iran): high-resolution stratigraphy of a continuous central Tethyan Permian–Triassic boundary section [PDF]

open access: yesFossil Record, 2020
The Permian–Triassic boundary section in the Aras Valley in NW Iran is investigated with respect to carbonate microfacies, biostratigraphy (particularly conodonts, nautiloids, and ammonoids), chemostratigraphy (carbon isotopes), and environmental setting.

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.
