“…Facies closely resemble the contemporaneous basinal upper portion of the Castillo Pedroso Formation in the Basque Cantabrian Basin (Fernandez-L6pez et aL, 1988;Aurell et al, 2002). Bedding is regular, as is common in hemipelagic environments.…”

“…For instance, in the Basque-Cantabrian and Asturias basins, significant thickness variations, attributed to dif ferential subsidence have been reported by Aurell et al (2003 ). Moreover, a widespread unconformity around the Early-Middle Jurassic boundary has been considered by these authors as indicating renewed activity of normal faults (see also Qu esada et al, 2005).…”

“…Fades pattern and biostratigraphic successions observed in the Cameros area reveal a striking similarity to the Basque-Cantabrian Basin, about 100 km to the NW (Fernandez-L6pez et al, 1988;Aurell et aL, 2002 ). Therefore, we propose to use the term Castillo Pedroso Formation for the rhythmic alternation of limestones (mst-wst) and organic-rich dark grey marls (Garda-Frank, 2007) in the Cameros area (see Fig.…”

Precise biochronological data (successive ammonites assemblages) from 29 measured sections, along with a bed by-bed facies analysis, allowed a detailed correlation between sections, the definition of a number of successive transgressive-regressive cycles and of two distinct sedimentation areas, as. well as the compilation of isopach maps for short time intelVals (duration of ammonites Zone/Subzone) and the assessment of sediment accumulation rates. Iberian Basin SpainDifferences in facies and thickness in the studied interval, and the sequential organization, reveal significant changes in the depositional environment.

Around the Triassic-Jurassic transition, a major tectonic rifting phase affected the northern part of the Iberian Basin (northeast Spain). Extensive normal faulting resulted in basin segmentation, as reflected by the rapid thickness and facies variation of the syn-rift, shallow-marine to supratidal carbonate-evaporite units. The upper Rhaetian-Hettangian syn-rift units exposed around the locality of Morata de Jalón (northeast Spain) provide good exposures that enable a precise sedimentological and structural analysis. The study of these units was achieved through geological mapping of an area of 10 km 2 , facies characterization, correlation of seven selected logs (vertical thickness from 40 m to 135 m), and measurement of normal faults, fractures and slump folds. The orientation of the major syn-sedimentary normal faults (NW-SE to NNW-SSE) suggests an origin through reactivation of late Variscan faults located within the Palaeozoic basement. However, the orientation of the newly formed faults and joints indicates a main N-S extension direction. The tectonosedimentary evolution of the studied basin can be summarized in two stages:1 at the end of the Triassic, a subsiding salina formed in the downthrown blocks of two normal faults -salina deposits were sourced from marine waters and, also probably, from the weathering of previously deposited evaporite-rich units; 2 during the Hettangian, tectonic reactivation combined with the long-term regional sea-level rise resulted in the formation of a tidal flat complex.These graded, in the areas of greater subsidence, into shallow-marine carbonate platform deposits. Syn-sedimentary fracturing affected the early lithified carbonates, favouring the formation of collapse-breccias in the tidal-flat environment, and limestone rudites (sedimentary breccias and conglomerates) in the subtidal domain, formed and partly transported as submarine debris flows.

Multi‐scale transgressive–regressive cycles from the mid‐Jurassic were recognised in the Central Lusitanian Basin, Portugal. These cycles allow the depositional evolution of the basin to be better understood and aid in the construction of stratigraphic sequences composed of three hierarchies. The stacking pattern of high‐frequency transgressive–regressive sequences forms larger clusters that define medium‐frequency transgressive–regressive sequences. Likewise, the stacking pattern of medium‐frequency transgressive–regressive sequences generates two Bathonian–early Callovian low‐frequency transgressive–regressive sequences. Integration of several methods supported the interpretation of facies associations representing clastic deposition in offshore to shoreface environments and carbonate sediments in outer to inner ramp settings. New data from calcareous nannofossils and dinoflagellate assemblages constrained the interval's Bathonian–early Callovian age, thus unveiling the Middle–Upper Jurassic disconformity and filling the Middle Jurassic stratigraphic record gap in the Central Lusitanian Basin. This study may be helpful for similar successions in Tethyan domains and comparable depositional settings elsewhere.
