Primary and diagenetic isotopic signals in fossils and hemipelagic carbonates: the Lower Jurassic of northern Spain
TL;DR: In this paper, stable isotope and trace element analyses of 230 Jurassic (Pliensbachian• Toarcian) samples from northern Spain have been performed to test the use of geochemical variations in fossils (belemnites and brachiopods) and whole-rock hemipelagic carbonates as palaeoceanographic indicators.

Geochemical correlation of oil from the Ayoluengo field to Liassic black shale units in the southwestern Basque-Cantabrian Basin (northern Spain)
TL;DR: A study of the Liassic sequence in the Basque-Cantabrian Basin has shown the presence of organic-rich (TOC, HI and S 2 up to 8.7%, 760 and 56.5 mg/g, respectively) Pliensbachian-early Toarcian black shales that constitute the only feasible source rock for Ayoluengo oil as discussed by the authors.
El «Jurásico Marino» del margen suroccidental de la Cuenca Vascocantábrica y su relación con la exploración de hidrocarburos.
Abstract: A type-section of the Lias and Dogger <"Marine Jurassic") of the southwestern margin of the Basquecantabrian Basin (Cantabria, Palencia and Burgos provinces) has been stablished based on both outcrop and subsurface data (well logs and seismic sections). Three potential hidrocarbon reservoirs are defined for this domain, the Hettangian Basal Dolomitic-Evaporitic Unit, the Lower Sinemurian Shallow Carbonate Ramp and the Middle Dogger Neritic and Pelagic Ramps, that mightget hidrocarbons from middle liassic organic-rich marls and black shales source-rocks developed in the adjacent Polientes-Sedano Basin
Correlación secuencial y sedimentológica entre registros de sondeos y series de superficie del Jurásico Marino de la Cuenca de Santander (Cantabria, Palencia y Burgos).
TL;DR: In this paper, a seismic scale cross-section of the Marine Jurassic of the Santander Basin (Lias and Dogger, western part ofthe Basque-Cantabrian Region, north Spain) is reconstructed based on both outcrop and well log data.
Registro de la composición isotópica del Jurásico inferior de la Cuenca Vascocantábrica: metodología analítica y relación con los depósitos orgánicos.
TL;DR: The Pliensbachian-lower Toarcian hemipelagic carbonates outcropping in the Reinosa area of northern Spain provide the opportunity to establish a high-resolution, biostratigraphically calibrated stable isotope stratigraphy as mentioned in this paper.
