High-resolution data from Laser Ablation-ICP-MS and by ICP-OES analyses at the Cretaceous/Paleogene boundary section at Agost (SE Spain) Sosa-Montes de Oca, Claudia de Lange, Gert J. Martínez Ruiz, Francisca Rodríguez Tovar, Francisco J. This "Data in brief" article was funded through Projects CGL2012-33281, CGL2012-32659, CGL2015-66835, and CGL2015-66830, Project RNM-05212 (Secretaria de Estado de I+D+I, Spain), Research Groups RNM-178 and RNM-179 (Junta de Andalucia) and FEDER funds. The research of Sosa-Montes de Oca was supported by a pre-doctoral fellowship from the Spanish Ministry, MINECO (BES-2013-064406). A high-resolution analysis of the distribution of major and trace elements across the Cretaceous/Paleogene boundary (KPgB) in the distal section of Agost (SE Spain) was performed. The KPgB sediments were drilled to recover a 22 cm-long core; the lower 5 cm corresponding to the uppermost Maastrichtian and the upper 17 cm to the lowermost Danian. The unconsolidated sediments were resin-embedded under O2-free conditions, cut and polished. Laser Ablation-Inductivity Coupled Plasma-Mass Spectrometry (LA-ICP-MS) analyses were conducted at 10 µm increments and a laser-beam of 80 µm. Discrete samples were taken immediately prior to the resin-embedding and analyzed by Inductivity Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Results obtained by both analytical methods (LA-ICP-MS and ICP-OES) are presented.
