This initial phase of research focused on the review of published data concerning the lithostratigraphy, biostratigraphy and palaeoenvironments of more than 20 major sedimentary basins along the Atlantic margins. Integrated stratigraphies for these basins were produced for the Jurassic and Early Cretaceous intervals, respectively, and are displayed on A3 tectonostratigraphic charts. These syntheses enable comparison of basins with regard to their general development and the timing of events. Two major phases of source rock deposition, Sinemurian to Toarcian and Oxfordian to Kimmeridgian, were identified, while important reservoir rocks are more randomly dispersed. Important unconformities in a number of basins occur in the Hettangian, Callovian, Berriasian and Late Aptian.
Fieldwork was undertaken on Fuerteventura, Canary Islands, Spain, where Mesozoic sediments of the ‘Basal Complex’ were studied. Sandstone, mudstone and igneous rock samples were collected for petrography, provenance, palynology and Rb/Sr dating, respectively.
Completed: September 2017.
