Paleomagnetic and paleoenvironmental implications of magnetofossil occurrences in late Miocene marine sediments from the Guadalquivir Basin, SW Spain [PDF]
Frontiers in Microbiology, 2014 Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than has been previously reported, their significance for paleomagetic and paleoenvironmental studies is not fully understood.

Magnetostratigraphy of sediments from Lake El'gygytgyn ICDP Site 5011-1: paleomagnetic age constraints for the longest paleoclimate record from the continental Arctic [PDF]
Climate of the Past, 2014 Paleomagnetic measurements were performed on sediments drilled from ICDP Site 5011-1 in Lake El'gygytgyn (67°30' N, 172°05' E) located in Far East Russian Arctic. The lake partly fills a crater formed by a meteorite impact 3.58 ± 0.04 Ma ago.

Geophysical Journal International, 2020 SUMMARY Quasi-linear field-dependence of remanence provides the foundation for sedimentary relative palaeointensity studies that have been widely used to understand past geomagnetic field behaviour and to date sedimentary sequences. Flocculation models are often called upon to explain this field dependence and the lower palaeomagnetic ...

Frontiers in Earth Science, 2021 The growth of the southern piedmont of the Himalayan boundary and its depositional setting has changed since uplift of the Himalaya due to continental Indian-Eurasian collision, which has resulted in variation in magnetic minerals in marine- and ...

Effect of compaction on the acquisition of a detrital remanent magnetization in fine-grained sediments [PDF]
Geophysical Journal International, 1978 Summary. Measurements of the detrital remanent magnetization (DRM) of redeposited deep-sea sediment of the silty clay grade are described. Variations in the magnitude of an observed remanence inclination error are related to conditions of sediment accumulation, contrasted here as grain-by-grain settling from a dilute dispersion or by settling from a ...

Detrital remanent magnetization in haematite-bearing Neoproterozoic Puga cap dolostone, Amazon craton: a rock magnetic and SEM study [PDF]
Geophysical Journal International, 2005 SUMMARY Neoproterozoic cap dolostones of the Araras Group (Mato Grosso, Brazil), deposited on top of glacial diamictites (Puga Formation, ∼630 Ma), yielded a dual polarity component providing al ow palaeolatitude for the Amazon craton. Because palaeomagnetic negative directions are very close to the present-day dipolar field, a rock magnetic and SEM ...

Subaerial and subaqueous deposition of loess: Experimental assessment of detrital remanent magnetization in Chinese loess [PDF]
Earth and Planetary Science Letters, 2010 Abstract Loess and intercalated paleosols on the Chinese Loess Plateau (CLP) are the most extensive and continuous terrestrial archive of geomagnetic and paleoclimate variations covering the last 2.6 Ma. A first-order time-frame has been established for these sequences using paleomagnetic polarity boundaries.

Magnetic record of deglaciation using FORC-PCA, sortable-silt grain size, and magnetic excursion at 26 ka, from the Rockall Trough (NE Atlantic) [PDF]
, 2016 Core MD04-2822 from the Rockall Trough has apparent sedimentation rates of ∼ 1 m/kyr during the last deglaciation (Termination I). Component magnetization directions indicate a magnetic excursion at 16.3 m depth in the core, corresponding to an age of 26.

Properties of a detrital remanence carried by hematite from study of modern river deposits and laboratory redeposition experiments [PDF]
, 1984 Although detrital haematite is often observed in red sedimentary rocks, its contribution to the magnetization is usually a matter of debate. Part of the problem is that the properties of magnetic remanence carried by detrital haematite are not well known.
