Pangea B: an artifact of incorrect paleomagnetic assumptions?
Annals of Geophysics, 2001 The detailed plate reconstruction within Pangea megacontinent has been an ongoing debate among the paleomagnetic community for decades. The Pangea B hypothesis, implying a 3500 km Triassic dextral megashear on the Gondwana-Laurussia limit, has been ...

Open Geosciences, 2023 Profile sampling, which causes missing or overlapping horizons, has been generally used while studying loess stratigraphy and paleoclimate. Conversely, drill sampling of thick loess can provide a relatively complete and actual record of the Quaternary ...

Frontiers in Earth Science, 2015 Geomagnetic reversals are global phenomena, for about 50 years the paleomagnetists attempted to acquire as many detailed records as possible using the magnetic memory of sediments and lava flows.

Geosciences, 2020 The Siberian Traps Large Igneous Provinces (LIP) emplacement is considered as one of possible triggers for the end-Permian global biotic crisis. However, relative timing of the onset of extinction and the main phase of the magmatic activity are not yet ...

Frontiers in Earth Science, 2022 The palaeoceanographic studies are largely limited by poor carbonate preservation in high-latitude regions. To improve our knowledge in this key area, we studied a sediment core (ANT32-RA05C) in terms of paleomagnetic and 230Th dating and geochemical ...

Geochemistry, Geophysics, Geosystems, 2021 New geochronologic and paleomagnetic data from the North American Midcontinent Rift (MCR) reveal the synchronous emplacement of the Beaver River diabase, the anorthosite xenoliths within it, and the Greenstone Flow—one of the largest lava flows on Earth.

Frontiers in Earth Science, 2022 The Eastern Qiangtang Terrane is an orogenic-like belt around the Eastern Himalayan syntaxis (EHS). The deformation history of this terrane must be known to understand how the EHS region responded to the Lhasa-Qiangtang collision and the closure of the ...

Short Note: A simple, alternative presentation of paleomagnetic demagnetization data [PDF]
Geofísica Internacional, 1999 Most research articles on paleomagnetism and rock-magnetism published since 1967 use vector component diagrams (known as Zijderveld diagrams) to describe and investigate the directional stability and intensity decay of remanent magnetization during ...

Detecting and correcting for paleomagnetic inclination shallowing of sedimentary rocks: A review
Frontiers in Earth Science, 2016 Magnetic anisotropy and the elongation/inclination (E-I) approaches have been increasingly employed as two important means for detecting and correcting the paleomagnetic inclination shallowing in sedimentary rocks that was first recognized sixty years ...

Geochemistry, Geophysics, Geosystems, 2021 The theory for recording of thermally blocked remanences predicts a quasilinear relationship between low fields like the Earth's in which rocks cool and acquire a magnetization.
