Searching for the Ordovician–Silurian boundary in Estonia, Latvia and Lithuania

“…According to Gailite et al (1987), the same is true for the topmost Remte Fm, but not for the Apaščia Fm, which still remains poorly dated. The Dobele Fm is characterised by graptolites from the Demirastrites pectinatus-D. triangulatus Zone up to the Stimulograptus sedgwickii Zone, whilst a tentative gap between the Apaščia and Dobele formations is drawn as equivalent to the C. cyphus Zone, which may be missing in the Apaščia-Dobele transition interval, judging from the published data (mainly Gailite et al 1987).…”

“…However, the question about the position of the system boundary is still open. The correlation with the global standard remains complicated because of the poor graptolite record of the Ordovician-Silurian transition in a large area reaching from northwestern Estonia (Nestor and Einasto 1997) across Latvia (Gailite et al 1987) and Lithuania (Paškevičius 1997) to marginal northeastern Poland (Podhalańska 1977). The only known section with graptolites in the boundary interval (Ulst 1992) has not been studied for other fossil groups and stable isotopes.…”

“…The correlation of the Ordovician-Silurian boundary strata in Fig. 2 is a compilation based on Gailite et al 1987, Nestor 2012, Männik 2014, Meidla et al 2020 and the correlation in Fig. 1.…”

“…The samples were chemically prepared using the optimal acetate 10 per cent buffered acetic acid technique for extracting phosphatic fossils [32] in the Micropalaeontological Laboratory in Institute of Geosciences at Vilnius University (Vilnius, Lithuania). Fish microremains were picked from residue samples onto microslides.…”
