Low-resolution osmium and rhenium concentrations from mudstone samples of the Kawaruppu section

DOI

This dataset contains osmium isotope ratios and osmium and rhenium concentrations from mudstone samples collected from the low-resolution interval of the Kawaruppu section, Nemuro Group, Hokkaido, Japan. The data cover the Upper Cretaceous-lower Paleogene interval across the Cretaceous-Paleogene boundary and were compiled for an integrated stratigraphic investigation of the boundary interval. Osmium isotope ratios and Os concentrations were measured by negative thermal ionization mass spectrometry (N-TIMS; TRITON, Thermo Fisher Scientific) and rhenium concentrations were measured by inductively coupled plasma quadrupole mass spectrometry (ICP-QMS; iCAP Q, ThermoFisher Scientific) at Japan Agency for Marine-Earth Science and Technology (JAMSTEC).
