Abstract

Name: Iberian seaway

Authors: Angela Alonso, Marc Floquet, Ramon Mas, and Alfonso Melendez

Location: From 39° to 43º north latitude and 0° to 5° 30' west longitude, Iberian Range, Spain

Geologic time interval: Late Cretaceous, middle Albian to latest Maastrichtian

Tectonic-sedimentary setting: Iberian plate; stable cratonic areas between Bay of Biscay (Cantabrian) opening and Tethyan closing

Basin type: Epeiric platform

Paleoclimate: Albian to late Santonian, warm and humid; Campanian, warm and semiarid; Maastrichtian, warm and humid

Platform type: Ramps, shelf

Platform geometry: Seaway oriented northwest-southeast, 500 km long, 250–350 km wide, and 500–1300 m thick

Facies and fossils: Micrites, marls, fine and coarse carbonates, minor amounts of evaporites and sandstones. Benthic and planktonic foraminifera, ammonites, rudists, molluscs, and algae

Systems tracts: Best represented are shallow ramp highstand system tracts; second are transgressive system tracts; lowstand system tracts are not represented

Stacking patterns: Retrogradational onlaping and progradational (sometimes sigmoidal) to aggradational parasequence sets
