Palaeoclimate evolution and sequence stratigraphy during Pliocene Shizigou stage, Qaidam Basin
Shiyou shiyan dizhi, 2020 The Qaidam Basin is a large transpressional Mesozoic to Cenozoic basin in the Tibet Plateau, West China. Since the Indosinian Movement, it has been in the subsidence stage and more than 3 trillion cubic meters of natural gas accumulated at the same time.

Quaternary stratigraphic regionalization and comprehensive framework in Nanling and adjacent areas
地质科技通报, 2021 The Quaternary sediments in the Nanling and adjacent areas are dominated by alluvial, eluvium and cave deposits, which have lacked of a unified stratigraphic and chronological framework.Based on the results of field survey and research on profiles, the ...

Stochastic resetting by a random amplitude [PDF]
Phys. Rev. E 103, 052123 (2021), 2021 Stochastic resetting, a diffusive process whose amplitude is "reset" to the origin at random times, is a vividly studied strategy to optimize encounter dynamics, e.g., in chemical reactions. We here generalize the resetting step by introducing a random resetting amplitude, such that the diffusing particle may be only partially reset towards the ...

The Salittu Formation in southwestern Finland, part I: Structure, age and stratigraphy [PDF]
Bulletin of the Geological Society of Finland, 2016 Because of the relatively low metamorphic grade, low strain and well-preserved early structures in volcanic and volcaniclastic rocks, the Orijärvi triangle (in the center of the larger Orijärvi area) is one of the few locations in the Svecofennian orogen

Dielectric properties and stratigraphy of regolith in the lunar South Pole-Aitken basin: Observations from the Lunar Penetrating Radar [PDF]
A&A 661, A47 (2022), 2022 We examine data obtained by the Lunar Penetrating Radar (LPR) onboard the Chang'E-4 (CE-4) mission to study the dielectric properties and stratigraphy of lunar regolith on the far side of the Moon. The data collected from January 2019 to September 2020 were processed to generate a 540 m radargram.

The SPICE carbon isotope excursion in Siberia: a combined study of the upper Middle Cambrian-lowermost Ordovician Kulyumbe River section, northwestern Siberian Platform [PDF]
, 2008 An integrated, high-resolution chemostratigraphic (C, O and Sr isotopes) and magnetostratigraphic study through the upper Middle Cambrian–lowermost Ordovician shallowmarine carbonates of the northwestern margin of the Siberian Platform is reported. The

Stratigraphic and Isotopic Evolution of the Martian Polar Caps from Paleo-Climate Models [PDF]
, 2022 Exposed scarps images and ice-penetrating radar measurements in the North Polar Layered Deposits (NPLD) of Mars show alternating layers that provide an archive of past climate oscillations, that are thought to be linked to orbital variations, akin to Milankovitch cycles on Earth.

The Depositional Record, 2022 Sea‐level fall is commonly inferred to generate a sharp‐based shoreface succession that displays an abrupt vertical transition from heterolithic, lower shoreface to sandy, upper shoreface deposits across a marine erosion surface.

Simulation-Based Inference of Surface Accumulation and Basal Melt Rates of an Antarctic Ice Shelf from Isochronal Layers [PDF]
, 2023 The ice shelves buttressing the Antarctic ice sheet determine the rate of ice-discharge into the surrounding oceans. The geometry of ice shelves, and hence their buttressing strength, is determined by ice flow as well as by the local surface accumulation and basal melt rates, governed by atmospheric and oceanic conditions.
