“…In this area, boundary fault displacement near the synthetic approaching transfer zone was relatively small, and this displacement gradually increased away from the approaching transfer zone along the strike of the boundary fault (Figure ), which formed a structural high on the hanging wall, based on the palaeomorphology (Figure ). Additionally, the footwall near the transfer zone was structurally low because of the higher stress concentration at the transfer zone (Khalil & Mc Clay, ). This palaeomorphology could have persisted until the end of the rifting phase.…”

“…A transfer zone may be located where clastic sediments enter the rift basin (Chen, Jia, & Zhang, ; Duffy, Brocklehurst, Gawthorpe, Leeder, & Finch, ; Faulds & Varga, ; Hemelsdaël & Ford, ; Morley, Nelson, Patton, & Mun, ; Qi, ), whereas the structural slope break controls the distribution of depositional systems through changes in accommodation (Alfaro & Holz, ; Feng et al, ; Lin et al, ; Paton, Spuy, Primio, & Horsfield, ; Prather, ; Ren, Lu, & Zhang, ; Vail et al, ; Wang et al, ). When the transfer zone and slope break zone are combined, sandbody distribution can be predicted effectively (Feng et al, ; Frimmel, Folling, & Eriksson, ; Gawthorpe & Leeder, ; Hou, He, Ni, & Wang, ; Khalil & Mc Clay, ; Lin et al, ; Lin, Zhen, Ren, Liu, & Qiu, ; Liu, Hao, Zhao, Zhang, & Yang, ; Liu, Meng, & Banerjee, ; Pavelicd, ; Smith & Jacobi, ). Many studies have been performed on the tectonic sequences of continental‐rift lacustrine basins (Deng, Guo, Wang, & Xie, ; Feng et al, ; Feng, Li, & Lu, ; Hou et al, ; Ji, Zhang, & Feng, ; Jia et al, ; Lin et al, ; Lin, Liu, Zhang, & Hu, ; Wang, Jiang, Huang, Jiang, & Gan, ; Wu et al, ; Zhou et al, ).…”

Different sequence types were formed in various stages associated with tectonic variations and changes of the sediment supply in the rift‐related Wenchang Formation. Based on cores, wire logging, and seismic data, the sequence stratigraphy, depositional systems, and controls on the depositional systems of the Wenchang Formation in the Lufeng Depression were studied. The Wenchang Formation developed braided‐delta, lacustrine, fan‐delta, and nearshore subaqueous fan deposits and represents one first‐order sequence and three second‐order sequences, indicating three stages of tectonostratigraphic evolution. (a) The early syn‐rift sequence (SSQ1) developed fan‐delta and shallow lacustrine deposits. (b) The rift climax sequence (SSQ2) contains the early rift climax systems tract and the middle‐late rift climax systems tract. The early rift climax systems tract formed primarily braided‐delta and shallow lacustrine deposits, whereas the middle‐late rift climax systems tract developed mostly semi‐deep to deep lacustrine deposits. (c) The late syn‐rift sequence (SSQ3) developed braided‐delta and shallow lacustrine deposits. In the SSQ3 transgressive systems tract, retrogradational parasequence sets developed along the southern dip slope because of the weak sediment supply from the Huilu low uplift, whereas westward aggradational–progradational parasequence sets developed along the long axis because of the stronger sediment supply from the Lufeng eastern low uplift. Tectonic activity primarily controlled the early syn‐rift and rift climax deposition; syn‐depositional faults formed the transfer zones and slope break zones. Three types of transfer zones for sedimentary transport into the basin were distinguished, including synthetic approaching transfer zones, strike ramps, and collateral transfer zones. Three types of slope break zones were also recognised, including fault scarp zones controlling fan deltas and nearshore subaqueous fans, fault terrace zones controlling low‐stand fan deltas, and antithetic fault terrace dip‐slope zones controlling braided deltas.

Campanian lacustrine organic-rich mudstones were deposited under a warm greenhouse climate in Egypt. In this study, integrated elemental geochemical analyses have been applied to discriminate the paleoweathering conditions, provenance, and tectonic setting of these mudstones. The studied samples are relatively enriched in Al, Ca, V, Sc, and Cr compared to Post-Archean Australian shales (PAAS). Their chondrite normalized REE patterns show enrichment in the light REE compared to heavy REE, with a negative Eu anomaly (Eu/Eu* = ∼0.77). The low values of Th/Sc (0.42), Zr/Sc (5.05), and Zr/Hf (36.3) for the studied samples indicate no input from recycled older sedimentary strata. The ratios of the compositional variability index (ICV = 0.76), K/Al (0.072), Al/Si (0.34), and K/Si (0.025) suppose that the mudstones are compositionally mature source rocks and originated in quiescent and low energy depositional environments. The average values of the chemical index of alteration (CIA = 82), chemical proxy of alteration (CPA = 94), and plagioclase index of alteration (PIA = 87) and ln(Al2O3/Na2O = 3.6) for the studied mudstones imply moderate to intensive chemical weathering. Moreover, the provenance sensitive elemental proxies (e.g., La/Sc, Th/Sc, Th/Cr, Cr/Th) and multiple discrimination diagrams reveal that the mudstones could be derived from intermediate igneous parent rocks. The lacustrine organic-rich sediments were sourced from a Phanerozoic to Proterozoic arc setting based on various tectonic discrimination diagrams.

“…Cochran and Karner, 2007;Khalil et al, 2020). The most important of these inherited crustal discontinuities were the WNW-ESE striking, left-lateral Neoproterozoic Najd shear zone which played a significant role in governing Miocene strain (Younes and McClay, 2002;Khalil and McClay, 2009). The relationship between magmatically attenuated lithosphere and pre-existing fabrics is thought to have controlled the length and orientation of border faults (Hubert-Ferrari et al, 2003;Bellahsen et al, 2013) and distribution of accommodation zones (Younes and McClay, 2002).…”

Tectono-Thermal Evolution of the Red Sea Rift

The Oligocene-Recent Red Sea rift is one of the preeminent examples of lithospheric rupture in the recent geological past, forming the basis for many models of how continental breakup occurs and progresses to the formation of new oceanic crust. Utilisation of low-temperature thermochronology in the Red Sea Rift since the 1980s has been key to constraining its spatio-temporal evolution, providing constraints for the propagation of strain and geomorphological development of its margins where datable syn-tectonic strata and/or markers are absent. We review the wealth of published apatite fission track and (U-Th-Sm)/He data from along the Red Sea, affording insights into the Oligocene-Recent thermo-tectonic evolution of the Nubian and Arabian margins. A regional interpolation protocol was employed to synthesise time-temperature reconstructions generated from the mined thermochronology data and burial histories produced from vitrinite reflectance and well data. These cooling-heating maps record a series of pronounced episodes of upper crustal thermal flux related to the development of the Oligocene-Recent Red Sea Rift. Assimilation of these regional thermal history maps with paleogeographic reconstructions and regional magmatic and strain histories provide regional perspectives on the roles of tectonism and geodynamic activity in Red Sea formation and their effects on rift margin development.
