Termination of Laurentia's Rapid Plate Motion at the Start of the Grenvillian Orogeny

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Late Mesoproterozoic to Neoproterozoic sedimentary sequences within the Lake Superior region preserve critical paleogeographic records of the position of Laurentia spanning from the end of Midcontinent Rift extension through to the end of the Grenvillian Orogeny.

Estimating Post‐Depositional Detrital Remanent Magnetization (pDRM) Effects for Several Lacustrine and Marine Sediment Records Using a Flexible Lock‐In Function Approach

Journal of Geophysical Research: Solid Earth
AbstractGeomagnetic field models over past millennia rely on two main data sources: archeomagnetic data provide snapshots of the geomagnetic field at specific locations, and sediment records deliver time series of the geomagnetic field at specific locations. The limited temporal and spatial coverage of archeomagnetic data necessitates the incorporation

Decoupling of paramagnetic and ferrimagnetic AMS development during the experimental chemical compaction of illite shale powder [PDF]

, 2017
Inclination shallowing of detrital remanent magnetization in sedimentary strata has solely been constrained for the mechanical processes associated with mud deposition and shallow compaction of clay-rich sediment, even though a significant part of mud ...

Oligo-Miocene magnetostratigraphy and rock magnetism of the Xishuigou section, Subei (Gansu Province, western China) and implications for shallow inclinations in central Asia. [PDF]

, 2001
Magnetostratigraphy of 222 remanent directions together with late Oligocene to early Miocene mammal and charophyte paleontology suggest that 2179 m of the Xishuigou section (Subei, Gansu Province, China) were deposited from ~26 to ~19 Ma.

Response of alluvial systems to Late Pleistocene climate changes recorded by environmental magnetism in the Añavieja Basin (Iberian Range, NE Spain) [PDF]

, 2016
Environmental magnetic proxies were analyzed in a relatively monotonous, ~25.3m thick alluvial sedimentary sequence drilled in the Añavieja Basin (NE Spain).

Apparent timing and duration of the Matuyama-Brunhes geomagnetic reversal in Chinese loess [PDF]

, 2014
       The Matuyama-Brunhes (MB) geomagnetic reversal in Chinese loess has been studied extensively as an important boundary for land-ocean stratigraphic and paleoclimatic correlations.

Obtaining High‐Resolution Magnetic Records From Speleothems Using Magnetic Microscopy

Geochemistry, Geophysics, Geosystems
Speleothems are mineral deposits capable of recording detrital and/or chemical remanent magnetization at annual timescales. They can offer high‐resolution paleomagnetic records of short‐term variations in Earth's magnetic field, crucial for understanding

Time resolved 2 million year old supernova activity discovered in Earth's microfossil record

, 2016
Massive stars, which terminate their evolution as core collapse supernovae, are theoretically predicted to eject more than 1E-5 solar masses of the radioisotope 60Fe. If such an event occurs sufficiently close to our solar system, traces of the supernova
