AB The Arroyofrio bed (Oxfordian-Callovian) from NE Iberian Chain represents a sedimentary shallowmarine deposit with iron oolites. The paleogeographic model shows two possible paleocurrent directions:i) normal to the Ejulve-Maestrazgo emerged area or ii) parallel to the shore line. Different techniques havebeen applied to analyze paleocurrents in different environments. AMS analysis together with thin sectionimage analysis is developed to test the application of AMS to unravel the sedimentary imprint linked totractive currents. The obtained results show a general parallelism between magnetic lineation and oolitearrangement analyzed from thin sections. The obtained results show an imbricated oolite pattern compatiblewith a paleocurrent direction N020-040ºE
