Short summary
Although significant progress in Early Jurassic cyclostratigraphy has been made in the last few decades, fewer studies have focused on the climatic and environmental impact of orbital cycles on the sedimentary record. This study presents an original orbitally modulated depositional model, which provides new insight into the formation of orbitally modulated organic-rich calcareous hemipelagic rhythmites accumulated in early Pliensbachian times in the northern Iberian palaeomargin.
