“…All sites revised in this work satisfy the following criteria. (a) They were sampled in weakly deformed deposits, without cleavage and/or penetrative structures to avoid the possible obliteration of the primary extensional magnetic fabric due to the reorientation of phyllosilicates and/or the formation of new mineral phases related to posterior compressional tectonic phases (García‐Lasanta et al, and references therein). (b) All analysed deposits correspond to red beds, a criterion to better compare magnetic fabrics coming from different works, as lithology (i.e.…”

Triassic stretching directions in Iberia and North Africa inferred from magnetic fabrics

et al. 2019

During the Triassic, Iberia and western North Africa displayed a unique situation in relation with the Central and North Atlantic opening and westward expansion of the Tethys. Unravelling the stretching direction in Triassic deposits of the studied area can help in our understanding of this scenario. The tectonic setting is characterized by localized basins with strong thickness variations greatly influenced by previous post-Variscan mechanical discontinuities. In this work, we revise and compile magnetic fabric data from eight Triassic depocentres in terms of defining the stretching direction (i.e. magnetic lineation), resulting from extensional deformation of this period. Data show the importance of the opening of the Atlantic rift as the leading process during the Triassic. Dextral transtension can explain the deflection of the extensional direction observed in most studied depocentres that is caused by the activity of previous major oblique faults.

“…However, regional and global sea‐level change curves show similar trends with negative significant rise, subjected the transgressive deposition more likely to tectonic results of the plate subduction (Haq, 2014; Haq & Al‐Qahtani, 2005; Meilijson et al, 2014). This may relate to the collision between AP and Eurasia, and ophiolite abundance along the northeast margin of the Arabian Platform (García‐Lasanta et al, 2018; Haq & Al‐Qahtani, 2005; Ozer et al, 2004) indicate stectonic activities occurred in the Late Cretaceous in the northwest part of the AP (Ashckenazi‐Polivoda et al, 2011; Ran et al, 2019; Zhao, Lai, Qin, Zhu, & Wang, 2017). The several to tens of metres deposition and subsequent hiatus between the Cretaceous and Palaeogene indicate that the transgression developed in a short time (Farouk et al, 2014; Meilijson et al, 2014).…”

Sedimentology and stratigraphy sequence of the north of Saudi Arabia: Implications for the evolution of the Neo‐Tethys in the Late Cretaceous

The Late Cretaceous sediments on the margin of the Arabia Plate contain information of tectonics and eustatic fluctuation of the Neo‐Tethys Ocean. The sedimentary association in the north of Saudi Arabia, combined with that from Jordan, Israel, and Egypt, revealed three fourth‐order sedimentary sequences that occurred in the Late Cretaceous and Palaeogene. The evolution of the sequences indicates that a most extensive transgression occurred in the south of Neo‐Tethys Ocean during that time, which deposited phosphorite and carbonate overlying the Devonian sandstone directly. The occurrence of thin and interbedded lithological layers implies vigorous fluctuation of the sea‐level during the transgression. We argue that the transgression is the results of tectonic activities and eustatic fluctuation, but may be closely controlled by the regional subduction and Neo‐Tethys collision.

“…Thus, we interpret our AMS records as a sensitive proxy for tectonic strain. Numerous studies have also speculated that the magnetic fabric is a sensitive proxy, which begins to develop after deposition and development ceases when diagenetic processes have ended (Burmeister et al, 2009;Cifelli et al, 2004;García-Lasanta et al, 2018;García-Lasantaa et al, 2013).…”

New constraints on the uplift history of the Liupan Shan can improve our understanding of the tectonic consequences of the collision of the Indian and Asian plates, including the timing of the uplift of the Tibetan Plateau. Here we present a detailed magnetostratigraphy for the Kaimengou section near the piedmont of the Liupan Shan, which reveals that it spans the interval from 19.8 to 12.8 Myr. Together with the results of measurements of the anisotropy of magnetic susceptibility, rock magnetic measurements show that the anisotropy of magnetic susceptibility is dominated by antiferromagnetic hematite and/or paramagnetic minerals, both of which are mainly controlled by the preferred crystallographic orientation, which can be used to record the tectonic history. During 19.5–14.0 Myr, the maximum principal axis (Kmax) showed a pronounced N‐S orientation and Kmin began to exhibit a girdled distribution in an E‐W direction, indicating a slight to moderate tectonic strain in an E‐W direction. And the strain can be reconfirmed be the shape parameter (T). We attribute the strain to far‐field influence by the collision of the Indian and Asian plates. We also present a tentative conceptual model, which explains how the E‐W compression fits within the general tectonic scenario for the uplift of the Tibetan Plateau.
