The Late Jurassic–Early Cretaceous Rifting

Tectono‐sedimentary evolution of Jurassic–Cretaceous diapiric structures: Miravete anticline, Maestrat Basin, Spain

“…During this second rifting stage the Jurassic carbonate platforms were broken‐up and newly formed faults defined individual basins, namely the Cameros, Maestrat and Columbrets basins, which were characterized by independent subsidence and stratigraphic histories (Etheve et al, 2018; Salas et al, 2001). More recently, in Martín‐Chivelet et al (2019) have distinguished a Neocomian (late Berriasian–Hauterivian) post‐rift phase between rifting cycles of Late Jurassic and Barremian–early Albian ages during the Late Jurassic–Early Cretaceous extension of the Maestrat Basin.…”

High‐Resolution C‐Isotope, TOC and Biostratigraphic Records of OAE 1a (Aptian) From an Expanded Hemipelagic Cored Succession, Western Tethys: A New Stratigraphic Reference for Global Correlation and Paleoenvironmental Reconstruction

“…Based on these estimates and a thickness of 37.5 m in Cau, the average sedimentation rate for OAE 1a is 2.9–3.7 cm/kyr, slightly higher than the average rate for the complete core. This difference can be explained by changes in accommodation space, as the early Aptian is considered to have higher subsidence rates than the late Aptian, due to a reduction in the intensity of extensional tectonics during the Aptian in the SICM (e.g., Martín‐Chivelet et al., 2019, 2002; Vera, 2004). Higher terrigenous and carbonate inputs fluxes might also have characterized the early Aptian, although the terrigenous:carbonate ratio did not vary significantly from the early to the late Aptian.…”

“…The Cau succession was deposited on the southern margin of the Iberian Plate, on the so‐called Southern Iberian Continental Margin (SICM; Martín‐Chivelet et al., 2002, 2019; Vera, 2004). At a global scale, the SICM was located at the western edge of the western Tethys, along the “seaway” between the Tethys and the Central Atlantic (Figure 1c), and at the antipodes of the major volcanic provinces developed during the Aptian, the Ontong‐Java, and Kerguelen plateaus that were intensely active during the early and late Aptian, respectively (e.g., Bralower et al., 1997; Jones & Jenkyns, 2001; Erba et al., 2015).…”

“…Eustatic and climate changes affected the Aptian sedimentary evolution of the SICM (e.g., Immenhauser, 2005; Immenhauser et al., 1999; Martín‐Chivelet et al., 2019). The studied section was located at a paleolatitude of 20–25°N (Masse et al., 1993; Figure 1c), interpreted to lie within the northern part of the equatorial arid belt (Chumakov et al., 1995).…”

3D reconstruction of syn-tectonic strata in a salt-related orogen: learnings from the Llert syncline (South-central Pyrenees)

“…The cross-sections integrate the few available dip data, as well as stratigraphic thicknesses documented by Martín-Chivelet et al (2019), after García-Senz (2002) and Lopez-Mir (2013). To interpret the structure at the subsurface, the top of the Anserola Formation was constructed using the Campo unconformity as reference horizon (Fig.…”
