Abstract:
We present magnetic susceptibility dataset from the lowermost Pliensbachian organic-rich hemipelagic Santiurde section (Basque-Cantabrian basin, north Iberian palaeomargin, Spain). The Santiurde section studied herein is exposed at exit 144 of motorway A67 (UTM X411431.091 Y4769002.593), approximately 50 km south-west of Santander city. The 22.5 m-thick succession is characterized by an alternation of limy and marl/shale beds. In order to determine if sedimentation was orbitally forced, a cyclostratigraphic analysis of the hemipelagic rythmites was undertaken. To this end, a total of 373 hand samples were collected and analysed for magnetic susceptibility and rock powder colour. Sampling was mainly carried out in 2019. The mass normalized low-field magnetic susceptibility was measured using a Kappabridge KLY-3 instrument (Geophysika Brno) housed at the Geology department of the University of the Basque Country (UPV/EHU), Bilbao, Spain.
