A detailed paleomagnetic and rock-magnetic investigation of the Matuyama-Bruhnes geomagnetic reversal recorded in tephra-paleosol sequence of Tlaxcala(Central Mexico)

open access: yesFrontiers 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.

Linking Siberian Traps LIP Emplacement and End-Permian Mass Extinction: Evidence from Magnetic Stratigraphy of the Maymecha-Kotuy Volcanic Section

open access: yesGeosciences, 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 ...

Magnetostratigraphy of the Pikermian fauna-bearing late Miocene Sivas Basin (central Anatolia, Turkey): fluvio-lacustrine sedimentation under stable climatic conditions across the Tortonian-Messinian boundary [PDF]

open access: yes, 2022
This study provides a new magnetostratigraphy for the stratigraphic interval that includes the late Miocene Haliminhanı and Hayranlı mammal fossil assemblages of the Sivas Basin (central Anatolia, Turkey).

Geochronology and Paleoenvironmental Changes of Late Pleistocene Sediments in the Ross Sea, Antarctica

open access: yesFrontiers 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 ...

Synchronous Emplacement of the Anorthosite Xenolith‐Bearing Beaver River Diabase and One of the Largest Lava Flows on Earth

open access: yesGeochemistry, 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.

The Early Cretaceous Zaduo Granite, Eastern Qiangtang Terrane (China)—An Attempt to Constrain its Paleolatitude and Tectonic Implications

open access: yesFrontiers 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]

open access: yesGeofísica 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

open access: yesFrontiers 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 ...

Understanding Nonideal Paleointensity Recording in Igneous Rocks: Insights From Aging Experiments on Lava Samples and the Causes and Consequences of “Fragile” Curvature in Arai Plots

open access: yesGeochemistry, 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.
