Essentials of Paleomagnetism [PDF]
Eos, Transactions American Geophysical Union, 2011 This book lives up to its title and does so in a manner that authors of modern science textbooks should seek to emulate. The book is produced as an affordable paperback and an even more affordable e‐book. It contains 16 chapters, several appendices, and more than 250 high‐quality illustrations. As a bonus, a considerable amount of related material that

Paleomagnetism of the Amazonian Craton and its role in paleocontinents
, 2016 In the last decade, the participation of the Amazonian Craton on Precambrian supercontinents has been clarified thanks to a wealth of new paleomagnetic data.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian Block (a fragment of the South China Block) remains unclear.

Pallasite paleomagnetism: Quiescence of a core dynamo
, 2016 Recent paleomagnetic studies of two Main Group pallasites, the Imilac and Esquel, have found evidence for a strong, late-stage magnetic field on the parent body.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.Abstract Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball Earth events, indicating that liquid‐water refugia existed somewhere on the surface. We examine the potential for refugia at the coldest time of a snowball event, before CO2 had risen and with high‐albedo ice on the frozen ocean, before it became darkened by dust deposition ...

Palaeomagnetism and tectonics of middle America and adjacent regions Part 1
Geofísica Internacional, 1981 Investigations, unified under the working hypothesis of plate tectonics, have produced a revolution in the earth sciences over the past decades. The effects of this have been profound since it has lead to a reexamination of the vast amount of available ...

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 908-924, July/August 2026.ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...
