New data on Ordovician stable isotope record and conodont biostratigraphy from the Viki reference drill core, Saaremaa Island, western Estonia

δ13C chemostratigraphy of the Middle and Upper Ordovician succession in the Tartu-453 drillcore, southern Estonia, and the significance of the HICE; pp. 195–200

“…The Saunja ICE peak is usually easily recognizable on δ 13 C curves of Estonian drillcores (Kaljo et al 2007, fig. 3; Ainsaar et al 2010, figs 3, 4;Hints et al 2014, fig. 2) as well as in the Jurmala R-1 drillcore, Latvia fig.…”

“…The MDICE is well represented in several drillcore sections of the East Baltic (e.g. Kerguta-565, Mehikoorma-421, Männamaa F-367, Ruhnu-500, Jurmala R-1, Viki; for reviews of the MDICE see Kaljo et al 2007;Ainsaar et al 2010;Hints et al 2014) as well as in Swedish sections on Öland (Tingskullen drillcore: Calner et al 2014) and in Dalarna (Kårgärde section: Ainsaar et al 2010). However, there are also densely-sampled sections in Estonia where the MDICE does not show up (e.g.…”

“…The uniqueness of the HICE in the Tartu-453 drillcore section, compared to the other sections (Kaljo et al 2008;Ainsaar et al 2010;Hints et al 2014), lies in the fact that the HICE extends substantially upwards (about 10 m) from the Porkuni-Juuru RSs boundary, into the marlstones of the Õhne Formation. In their recent overview on the Hirnantian chemostratigraphy in Sweden and elsewhere Bergström et al (2014, fig.…”

CHITDB: a database for documenting and analysing diversification of Ordovician–Silurian chitinozoans in the Baltic region

“…The new CONOP9 model incorporates also data on K-bentonites and carbon isotope excursions from numerous studies (e.g. Kaljo et al 2003Kaljo et al , 2007Kiipli et al 2010Kiipli et al , 2011Kiipli et al , 2013Hints et al 2014b). Full explanation of the model, its scaling and calibration, and interpretation of the diversity curves are beyond the scope of this report, but a few comments are necessary.…”
