“…A 193 nm wavelength COMPex 102 ArF excimer laser ablation system (Lambda Physik, Göttingen, Germany) connected to an Element 2 sector field ICP-MS (Thermo Scientific, Bremen, Germany) was used for all LA-ICP-MS analyses at the GML of Utrecht University (The Netherlands). The data were subsequently processed following the procedure of Sosa-Montes de Oca et al (2018aOca et al ( , 2018b. The LA-ICP-MS specifications as well as elemental ratios used in this paper are summarized in Table 1.…”

“…Numerous KPgB sections are known worldwide [4], the Agost site (SE, Spain) being a very wellpreserved and well-exposed marine distal section [5]. This section has been profusely studied, due to its exceptionally, expansive and continuous sedimentary record, making the Agost site ideal for highresolution analyses [6].…”

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 O 2 -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. (Further interpretations and discussion are included in Sosa-Montes de Oca et al., 2018 [6]).

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.
