Coupled biostratigraphy and chemostratigraphy at Lanna, Sweden : A key section for the Floian–lower Darriwilian interval (Lower–Middle Ordovician)
The Lanna area in the province of Närke, south-central Sweden, hosts a succession of cool-water carbonate strata that are largely devoid of tectonic and diagenetic alteration, and span the Floian through lower Darriwilian Global stages (Ottenbyan–Kundan Regional stages). In this study we assess the integrated biostratigraphic and chemostratigraphic framework for the Ordovician sequence at Lanna, u
