Cave Dripwater Magnetic Minerals Record Seasonal Rainfall Variability: New Insights From a 5‐Years Field Monitoring in Central China

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Stalagmites provide an invaluable archive at high‐resolution for paleoclimate studies. However, it is challenging to extract independent hydroclimate signals from stalagmites due to the scarcity of reliable hydrological proxies. Although the magnetic parameters of stalagmites have shown great potential in recording regional hydrological ...

Geomagnetic relative paleointensity and direction during the last 40,000 years obtained from a sediment core in the Nankai Trough

Earth, Planets and Space
Construction of regional geomagnetic secular variation curves for the last several tens of thousands of years is important for understanding the behavior of non-dipole fields and applications to geochronology.

Magnetic Mineral Assemblages of Diagenetically Reduced Sediments and Their Contributions to Paleomagnetic Signals

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract During early diagenesis of marine sediments, iron‐bearing minerals undergo a series of redox reactions until they reach equilibrium with reactive chemical components. Paleomagnetic records in the sediments subjected to severe diagenesis can be distorted or lost due to iron mineral dissolution, and hence these sediments were often excluded from

Post-depositional detrital remanent magnetism in reconstituted deep sea sediment

, 1975
Evidence of disturbance by benthic burrowing organisms is commonly observed in deep-sea sediment cores but these same cores often possess good magnetic records, especially of field reversals. The natural remanent magnetism (NRM) of these burrowed sediments cannot be a depositional detrital remanence (DRM) but must rather have been acquired at some ...

The magnetization of sediment cores from the eastern basin of the North Atlantic Ocean [PDF]

, 1963
The magnetization of sediment from the eastern basin of the North Atlantic Ocean is due to magnetite. The variation of the directions of magnetization due in cores from the abyssal plains depends upon the sedimentary features which are the result of ...

Implications of Northwest Pacific Ocean Eolian Records for Northern Hemisphere Wind System Evolution

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Northwest Pacific Ocean sedimentary eolian records preserve abundant information about the temporal evolution of Northern Hemisphere atmospheric circulation. The large spatial scale of these wind systems means that they play key roles in driving dust transportation from inland areas to the open ocean. However, the altitudinal range of dominant

Magnetic Component Unmixing of a Lacustrine Sedimentary Drill Core from Heqing Basin

Atmosphere
Long and continuous lacustrine sediments in Southwest China provide exceptional records of the Indian summer monsoon (ISM) evolution. Rock magnetic and environmental magnetic methods have significant roles in these lacustrine studies. However, lacustrine
