“…However, although the very high-resolution seismic reflection method proved to be a cost-effective tool to estimate the potential size of carbon stocks associated with the P. oceanica matte, J o u r n a l P r e -p r o o f calibration of data by coring remains essential to ensure a good interpretation of the stratigraphic sequence (i.e. depth and thickness ; Onajite, 2014) but also to determine precisely the Corg content and the spatio-temporal dynamic of these belowground formations (Lo Iacono et al, 2008). Several studies have shown that matte accretion and carbon accumulation over long periods of time are influenced by the complex interactions of multiple biotic or abiotic factors (Mateo et al, , 2002Serrano et al, 2016b;Mazarrasa et al, 2018).…”

“…We model dynamic earthquake rupture scenarios with a principal listric fault and many off-fault fractures. In deep sedimentary basins, listric faults, extending to basement depth and forming traps for natural resources near geological reservoirs, are common (Figure 2a and e.g., Withjack et al (2002); Onajite (2013); Dixon et al (2019)). We note that fault listricity is expected to impact rupture dynamics and seismic radiation (Passone & Mai, 2017;Rodgers et al, 2019).…”

Fault‐damage zones comprise multiscale fracture networks that may slip dynamically and interact with the main fault during earthquake rupture. Using 3D dynamic rupture simulations and scale‐dependent fracture energy, we examine dynamic interactions of more than 800 intersecting multiscale fractures surrounding a listric fault, emulating a major listric fault and its damage zone. We investigate 10 distinct orientations of maximum horizontal stress, probing the conditions necessary for sustained slip within the fracture network or activating the main fault. Additionally, we assess the feasibility of nucleating dynamic rupture earthquake cascades from a distant fracture and investigate the sensitivity of fracture network cascading rupture to the effective normal stress level. We model either pure cascades or main fault rupture with limited off‐fault slip. We find that cascading ruptures within the fracture network are dynamically feasible under certain conditions, including: (a) the fracture energy scales with fracture and fault size, (b) favorable relative pre‐stress of fractures within the ambient stress field, and (c) close proximity of fractures. We find that cascading rupture within the fracture network discourages rupture on the main fault. Our simulations suggest that fractures with favorable relative pre‐stress, embedded within a fault damage zone, may lead to cascading earthquake rupture that shadows main fault slip. We find that such off‐fault events may reach moment magnitudes up to Mw ≈ 5.5, comparable to magnitudes that can be otherwise hosted by the main fault. Our findings offer insights into physical processes governing cascading earthquake dynamic rupture within multiscale fracture networks.

“…The bottoms of the Dushanzi and Xiyu Fms in profile BB′ are dated at ∼5.2 and ∼2.1 Ma, respectively (Lu et al, 2010, Figure 2b). Assuming a constant sedimentation rate between two consecutive reflectors in one formation since the same formation shares a quasi-equal seismic wave velocity (Onajite, 2014), the age of all recognized seismic reflectors in the Shawan thorough Xiyu Fms were interpolated (Tables S1 and S2 in Supporting Information S1).…”

In an orogenic belt-foreland basin setting, sediments from the mountain are transported downstream and accumulate in foreland basins. Sediments routing through the network of rivers display downstream grain size fining due to sorting and abrasion (Paola et al., 1992). A grain size transition from gravel to sand, termed the gravel-sand transition (GST;Ferguson et al., 1996), occurs in a short downstream distance from the sediment source. The GST is preserved in the stratigraphy of a sedimentary basin as the conglomerate-sandstone transition (CST; e.g., Dubille & Lavé, 2015). The position of the CST in a foreland basin succession is determined by basin subsidence, sediment supply, and grain size (Allen et al., 2013;Armitage et al., 2011), and all these factors depend on the interactions of tectonics in the adjacent mountains and regional climate (Dingle et al., 2016(Dingle et al., , 2017Duller et al., 2010;Quick et al., 2020). The propagation of the orogenic wedge toward to the foreland drives the forelandward migration of the coupled foreland basin system as well as sedimentary facies (Flemings & Jordan, 1989
