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.
