High‐resolution record of geomagnetic excursions in the Matuyama chron constrains the ages of the Feiliang and Lanpo Paleolithic sites in the Nihewan Basin, North China

Geochemistry, Geophysics, Geosystems, 2012
The Nihewan Basin (40°N) in North China is a rich source of Early Pleistocene Paleolithic sites and thus a key area for studying early human evolution in high‐latitude (from an early human perspective) East Asia.

Magnetostratigraphy and Radiometric Chronology

The Quaternary Research (Daiyonki-Kenkyu), 1977
This paper briefly reviews the history and present status of magnetostratigraphy, and re-examines the usefulness of magnetostratigraphy in absolute chronology. At present, two different kinds of time scale are used as standards for magnetostratigraphic age determination.

Magnetic‐A: The New R‐Based Toolbox for Analysis of Paleomagnetic Data

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Paleomagnetic remanence in rocks and sediments provides a unique means to constrain stratigraphic records in both space and time. This is because of the symmetry of the paleomagnetic field with respect to Earth's spin axis over geological time, and the global synchronicity of magnetic field reversals.

Speleogenesis in a lens of metamorphosed limestone and ankerite: Ochtiná Aragonite Cave, Slovakia

International Journal of Speleology, 2021
The Ochtiná Aragonite Cave (Western Carpathians) represents an unique natural phenomenon. It originated under particular lithological and hydrogeological conditions of the Ochtiná Karst in which several isolated lenses of Paleozoic crystalline limestone (

Organic Carbon Burial following the Middle Eocene Climatic Optimum (MECO) in the central - western Tethys

, 2010
We present trace metal geochemistry and stable isotope records for the middle Eocene Alano di Piave section, NE Italy, deposited during magnetochron C18n in the marginal Tethys Ocean. We identify a $\sim$ 500 kyr long carbon isotope perturbation event we

Climate and Tectonic Forcing of Depositional Evolution in the Southern North China Basin Since ∼3 Ma

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
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 ...

Addendum to “Late Cenozoic magnetochronology and paleoenvironmental changes in the northern foreland basin of the Tian Shan Mountains” by Jimin Sun, Qinghai Xu, and Baochun Huang [PDF]

, 2008
International audienceSun et al. (2007) constructed a magnetostratigraphic record of the Kuitun River section (Xinjiang Province, China) and reinterpreted a magnetostratigraphic record from the same section previously published by Charreau et al. (2005).

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

The chronology and rotational kinematics in the South-Eastern Jaca Basin (Southern Pyrenees): Las Bellostas section

Geologica Acta, 2022
Despite the large number of magnetostratigraphic studies in the South Pyrenean Basin aiming to calibrate the basin chronostratigraphy and the biostratigraphic scales, the South Eastern Jaca Basin remains unexplored from this perspective, and its relation
