Latest Ordovician age of the Spinachitina fragilis Chitinozoan Biozone in Baltoscandia [PDF]
Estonian Journal of Earth Sciences, 2023 The global Spinachitina fragilis Chitinozoan Biozone has been considered the lowermost Silurian zone in most publications. S. fragilis was first described from the Ohesaare drill core, Estonia, and utilised as a Baltic regional zonal taxon together with ...

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

Integration of Darriwilian (Middle Ordovician) delta C-13(org) chemostratigraphy with graptolite biostratigraphy in the classical Rostanga area in northwestern Scania (southern Sweden) [PDF]
, 2020 The largely covered Middle Ordovician succession in the classic geological Rostanga area in northwestern Scania has not been studied for some 80 years. A new drill core through a succession ranging from the lower-middle Darriwilian to the lower Sandbian ...
