Perspectivas de los estudios de arqueomagnetismo en Sudamérica [PDF]

open access: yes, 2014
Archaeomagnetism is the study of past geomagnetic field variations using bricks, pottery and campfire stones. This is a multidisciplinary work in which archaeologists, historians and geophysicists play important roles.

Reconstructing Holocene geomagnetic field variation: new methods, models and implications [PDF]

open access: yes, 2014
Reconstructions of the Holocene geomagnetic field and how it varies on millennial timescales are important for understanding processes in the core but may also be used to study long-term solar-terrestrial relationships and as relative dating tools for ...

Analysis of geomagnetic field intensity variations in Mesopotamia during the third millennium BC with archeological implications [PDF]

open access: yes, 2020
We present new archeointensity results obtained at two multi-layer archeological sites, Tell Atij and Tell Gudeda (northeastern Syria), dated from the Early Bronze Period in the third millennium BC.

Magnetism of Al-substituted magnetite reduced from Al-hematite

open access: yes, 2016
Aluminum-substituted magnetite (Al-magnetite) reduced from Al-substituted hematite or goethite (Al-hematite or Al-goethite) is an environmentally important constituent of magnetically enhanced soils. In order to characterize the magnetic properties of Al-

Cooling rate effects on paleointensity estimates in submarine basaltic glass and implications for dating young flows [PDF]

open access: yes, 2005
Cooling rate effects on the intensity of thermoremanent magnetization (TRM) have been well documented in ceramics. In that case, laboratory cooling is generally more rapid than the initial cooling, leading to an overestimate of the paleofield by 5-10% in

A comparison of Thellier-type and multispecimen paleointensity determinations on Pleistocene and historical lava flows from Lanzarote (Canary Islands, Spain) [PDF]

open access: yes, 2016
Sixteen Miocene, Pleistocene, and historic lava flows have been sampled in Lanzarote (Canary Islands) for paleointensity analysis with both the Coe and multispecimen methods.

The geomagnetic field intensity in New Zealand: palaeointensities from Holocene lava flows of the Tongariro Volcanic Centre [PDF]

open access: yes, 2017
Very few absolute palaeointensity data exist from Holocene-aged rocks in New Zealand. Here we present a new suite of high-quality palaeointensities, supported by detailed rock magnetic investigations.

New directional archeomagnetic data of burned cave sediments from Switzerland and geomagnetic field variations in Central Europe [PDF]

open access: yes, 2017
This paper presents new directional archeomagnetic data from nine Meso-/Neolithic fireplaces, sampled in a cave shelter, at Arconciel, in western Switzerland.
