Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Discharge of hydrothermal fluids through sediment at the Escanaba Trough, Gorda Ridge (ODP Leg 169): assessing the effects on the rock magnetic signal [PDF]

, 2000
An integrated rock-magnetic and multivariate statistical analysis of a suite of sediment samples recovered from ODP Sites 1037 and 1038 (Leg 169, Escanaba Trough, Gorda Ridge spreading center, NE Pacific Ocean) has been carried out to assess the use of

Magnetism as a Proxy for Sedimentary REY Enrichment in the Eastern Pacific Ocean and Its Potential Use for Identifying Deep Ocean REY

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Rare earth elements and yttrium (REY) are critical for advanced technological and environmental applications. REY‐enriched deep‐sea sediments have attracted attention as significant potential REY resources. However, efficient identification of these deposits in the open oceans is a persistent challenge.

Palaeomagnetism of Middle Ordovician Carbonate Sequence, Vaivara Sinimaed Area, Northeast Estonia, Baltica [PDF]

, 2016
The hill range of Vaivara Sinimaed in northeast Estonia consists of several narrow east-to northeast-trending glaciotectonic fold structures. The folds include tilted (dips 4-75 degrees) Middle Ordovician (early Darriwilian) layered carbonate strata that

Remagnetization of Lower Cretaceous Limestones in the Western Tethyan Himalaya and Its Tectonic Implications for the India‐Asia Collision

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The drift history of the Tethyan Himalaya provides key constraints on the India‐Asia collision, Himalayan‐Tibetan orogenesis, and associated global climate change. Here we present rock magnetic, petrographic, geochronologic, and paleomagnetic results of the Bolinxiala Formation limestones in the western Tethyan Himalaya.

Magnetic mineral study of Holocene marine sediments from the Alfonso Basin, Gulf of California - implications for depositional environment and sediment sources [PDF]

Geofísica Internacional, 2009
Results of a rock magnetic study of marine sediments from the Alfonso Basin, Bay of La Paz are used to investigate sediment sources and depositional environment in the southern Gulf of California during the Holocene.

Depth of post-depositional remanence acquisition in deep-sea sediments: a case study of the Brunhes-Matuyama reversal and oxygen isotopic Stage 19.1 [PDF]

, 1990
Although post-depositional remanent magnetization (PDRM) in deep-sea sediments appears to be acquired during the earliest stages of sediment compaction, the natural variability of the PDRM lock-in depth in deep-sea sediments is poorly understood and as ...

New Insights Into the Proposed Geomagnetic Excursion Hilina Pali From High‐Resolution Lake Sediment Cores From the Polar Ural Mountains, Arctic Russia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract This study presents paleomagnetic records from three 24 m‐long sediment cores from the neighboring lakes Bolshoye Shchuch'ye and Maloye Shchuch'ye, located about 10 km apart in the Polar Urals in northern Russia. The age model, based on radiocarbon dating and varve counting, shows that the sediment sequences reach back up to about 23.5 ka cal.

Origin of Magnetic Instability in Sediment Cores From the Central North Pacific [PDF]

, 1974
Previous paleomagnetic studies on deep-sea sediment cores from the central North Pacific have shown that the natural remanent magnetization (NRM) of these 'red clay' sediments was unstable below several meters depth in each core.

Bending the Sierra Madre Oriental: A Paleocene Orocline

Tectonics, Volume 44, Issue 11, November 2025.
Abstract The Sierra Madre Oriental belt of the Mexican thin‐skinned fold‐and‐thrust belt, which formed during the Late Cretaceous due to the subduction of the Farallon Plate beneath North America, exhibits a pronounced curvature of approximately 100°, concave to the southwest.
