Geochemical and age model data from Frasnian–Famennian extinction records from the H-32 core (Iowa, USA), the Kowala Quarry (Poland), and Sinsin (Belgium)@en

Geochemical data for three sedimentary records of the Frasnian–Famennian extinction and Upper Kellwasser Event, from the H-32 core (Iowa, USA), the Kowala Quarry (Poland), and Sinsin (Poland), together with time vs depth information for the revised age model of the H-32 core. Nitrogen-isotope and nitrogen content data are included for all three sites, together with biomarker information for Kowala and the H-32 core, carbon isotope data for Kowala and Sinsin, total organic carbon for the H-32 core and Sinsin, Rock Eval data from the H-32 core, phosphorus and aluminium content data, and P/Al and TOC/P ratios, from the H-32 core, and time-depth data from the H-32 core.
