Several chemical weathering proxies for siliciclastic sedimentary deposits have been proposed over the last fifty years. However, only a few studies have evaluated their robustness for paleoclimate interpretation.

Abstract Tectonic subsidence, sea level, and paleoclimate reconstructions using marine records rely on accurate decompaction of the sediment column. Over time, increased overburden pressure from burial decreases sediment porosity with depth. The porosity‐depth relationship is lithology‐dependent and can be represented by an exponential function ...

An observation-based causal framework linking Barents–Kara sea ice to European heatwaves
European summers have become increasingly dominated by severe and persistent heatwaves (HWs), with major societal and economic consequences. While progress has been made in the last decade in linking Arctic sea ice decline to midlatitude extremes, the ...

Climate and Tectonic Forcing of Depositional Evolution in the Southern North China Basin Since ∼3 Ma
Abstract Marginal basins provide sensitive yet incomplete records of climate and tectonic forcing, and the southern North China Basin provides an ideal setting to decode these interactions since the late Pliocene. A 135.6‐m borehole sequence, the XiaoQian (XQ) core, recovered from the Fuyang region, was dated using AMS 14C, OSL, and ESR, supplemented ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Abstract Using outputs from eight Coupled Model Intercomparison Project Phase 6/Paleoclimate Model Intercomparison Project phase 4 models, we compare the hydrography and surface ocean circulation in the Arctic and sub‐Arctic regions across three climate states: the pre‐industrial (PI; 1850 CE), the Last Interglacial (LIG; 127 ka BP), driven by strong ...

Abstract The Paleocene‐Eocene thermal maximum (PETM, ∼56 Ma) is marked by a massive and rapid rise in atmospheric CO2 and ∼5°C of global warming. It is globally characterized by a negative carbon isotope excursion (CIE), and, at least locally, is preceded by a pre‐onset excursion (POE).

Abstract Plant wax hydrogen isotopes (δ2H) preserved in lake sediments provide valuable insights into past climatic changes. However, lake catchments often experience local shifts in vegetation type that can yield distinct isotopic signatures in the sediments, potentially obscuring hydroclimatic signals.

Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.
