A new upper Middle Ordovician–Lower Silurian drillcore standard succession from Borenshult in Östergötland, southern Sweden: 1. Stratigraphical review with regional comparisons (original) (raw)

A new drillcore standard succession from Borenshult in Östergötland, southern Sweden, establishes a significant contribution to understanding Lower Paleozoic stratigraphy through d 13 C chemostratigraphy. This study outlines the regional comparisons with Estonian drillcores, revealing striking similarities and new insights into trans-Baltic correlations. The findings offer a clearer picture of the historical geological changes, with implications for biostratigraphy and global carbon isotope stratigraphy.
