Remagnetization of Marcellus Formation in the Plateau Province of the Appalachian Basin

Frontiers in Earth Science, 2019
An integrated paleomagnetic, magnetic fabric, and petrographic study of two cores (EC, oriented; DB, unoriented) in the Devonian Marcellus Formation from the Plateau Province (PA) indicates the presence of chemical remanent magnetizations (CRMs) and ...

Separating Geometry‐ From Stress‐Induced Remanent Magnetization in Magnetite With Ilmenite Lamellae From the Stardalur Basalts, Iceland

Geochemistry, Geophysics, Geosystems, 2020
Realistic geometries of magnetite grains from the Stardalur volcano, Iceland, were obtained by Focused Ion Beam Scanning Electron Microscopy nanotomography. These magnetite grains are subdivided by oxidation‐exsolution lamellae of ilmenite.

Investigating the utility of a high-temperature Thellier-style paleointensity experimental protocol

Earth, Planets and Space, 2021
High-quality data are vital to the research field of paleointensity, which has long suffered from poor-quality and/or sparse data. Previous paleointensity work has established that repeatedly heating specimens increases the opportunity for thermochemical

Topographical influence on pedogenesis – Insights from Rock Magnetism

, 2020
Topography being a pedogenic factor influences the physico-chemical and biological properties of soil profiles. Besides, the magnetic characteristics of soil profiles may also be varied, as iron minerals in soils are strongly redox sensitive.

New Rock Magnetism and Magnetic Fabrics Studies on the Late Triassic Volcanic Rocks from Qaidam Block, Northern Tibetan Plateau

Minerals
The Qaidam Block, located at the northern Qinghai–Tibet Plateau, is a pivotal area in unraveling the closure time of the Kunlun Ocean basin which might have recorded the transformation process between the Proto-Tethys and Paleo-Tethys Ocean basins ...
