AbstractAn immiscible two-phase model based on the incompressible Navier-Stokes (N-S) equations is used to simulate the air blast generated by an avalanche. For simplicity, the avalanche is treated as an assembly of monodisperse spherical grains and de…
AbstractThe origin of geological depressions abounding on Mars and other planetary bodies remains poorly understood, partially due to the limited variability in the geological settings of existing terrestrial analogs. Here, we present a new terrestrial…
AbstractU-Pb dating of single detrital zircon grains by laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) paired with Hf and O isotopic and trace-element analyses provide first-order indicators of the Late Cretaceous–Cenozoic evol…
AbstractThis work proposes a new lateral foreland thrusting model based on geological evidence and 3-D particle discrete-element simulation to explain the Longmenshan southeastward thrusting during the closure of the Songpan-Ganze basin. The Late Trias…
AbstractAccurate reconstruction of Laurentide Ice Sheet volume changes following the Last Glacial Maximum is critical for understanding ice sheet contribution to sea-level rise, the resulting influence of meltwater on oceanic circulation, and the spati…
AbstractThe Himalaya is known for dramatically rugged landscapes including the highest mountains in the world. However, there is a limited understanding of the timing of attainment of high elevation and relief formation, especially in the Nepalese Hima…
AbstractThe global pattern of plant evolution through the Permian–Triassic mass extinction is uncertain, and the extent to which land plants were affected is debated. Detailed studies undertaken at a regional scale can help evaluate this floral transit…
AbstractWhether deformation of exhumed crust in a collisional orogen is driven by buoyancy or tectonic stress remains uncertain. The Sulu orogen in eastern China contains slowly subducted and exhumed high-pressure (HP)–ultrahigh-pressure (UHP) terranes…
AbstractConstraining tectonic uplift history within the Tibetan Plateau is critical to understanding its deformational response to continental collision. However, it is difficult to extrapolate orogen-scale uplift history from any single method alone. …
AbstractAlternative depositional models for the Early Cretaceous McMurray Formation between a dominantly continental and marginal marine settings remain a controversial topic. The source-to-sink model can be inverted to reconstruct ancient sediment-rou…
