ENSO‐Mediated Linkage Between the East Asian Summer Monsoon and Cordilleran Ice Sheet Discharge During MIS 3

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

High‐Precision Delineation of Curie Point Depth Under Remanent Magnetization Using Physics‐Informed Neural Networks

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Impacts of diagenetic process on reservoir quality of the Middle Cretaceous Upper Sarvak Formation in one of oil fields in the Abadan Plain, SW Iran [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2016
During the precipitation of Sarvak formation imprints of climate, tectonic and sea level fluctuation lead to some of the most prolific reservoirs in Zagros and Persian Gulf basins.

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

Chamber‐by‐Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA‐ICP‐MS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

Relaciones entre el ambiente de sedimentación y los procesos diagenéticos en las areniscas del Buntsandstein del Umbral de Ateca (Cordillera Ibérica). [PDF]

, 1990
Los sedimentos de facies Buntsandstein del Umbral de Ateca se depositaron en un medio de transición, en áreas intra y supramareales, dentro de un sistema deltaico dominado por procesos de "crevassing".

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

The Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

Drivers of Benthic Iron Fluxes and the Pore‐Water Iron Isotopic Signature in Surface Sediments of South Georgia Fjords, Sub‐Antarctica

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Benthic iron (Fe) fluxes from coastal sediments support phytoplankton blooms downstream of subpolar islands. We combine solid‐phase and pore‐water geochemical data, including its iron isotopic signature (δ56Feaq), to identify the main drivers of benthic Fe fluxes from sub‐Antarctic fjord and shelf sediments of South Georgia, and to evaluate ...
