AbstractFluid overpressure is a common phenomenon in sedimentary basins, and overpressure induced by hydrocarbon generation has attracted considerable attention. However, direct temporal constraints are lacking, and the evolutionary process remains poo…

AbstractIntracontinental volcanism inboard of growing transform boundaries has often been associated with the opening of slab windows following the collision of an oceanic spreading ridge with the continental margin. Yet, the specific drivers of supra-…

AbstractDolomite formation remains a debated topic in sedimentary geology, particularly concerning the mechanisms driving its precipitation under natural conditions. While microbial processes have been well studied, the influence of abiotic factors, su…

AbstractReconstructing past climates in hot, arid regions is challenging due to scarce archives and proxies. Clumped isotopes (Δ47) on sabkha calcite-aragonite minerals might alleviate this situation. We apply the Δ47 technique to modern and middle Mio…

AbstractOur knowledge of the Cretaceous history of the northwestern Pacific plate relies on tectonic reconstructions that lack geochronologic and geochemical constraints due to the paucity of sampling in this area. We present new age and compositional …

AbstractThe impact of recurrent landslides on submarine canyon morphology, sediment dynamics, and tsunami hazard is poorly understood. This study presents the first detailed inventory of earthquake-induced submarine landslides, using high-resolution (2…

AbstractTonian true polar wander (TPW) events, first reported from South China (SC), were later confirmed by a paleomagnetic study of Svalbard. However, recent studies have argued that the dispersion of the Tonian paleomagnetic poles in SC may instead …
