Reverse magnetic anomaly controlled by Permian Igneous rocks in the Iberian Chain (N Spain) [PDF]

open access: yesGeologica Acta, 2014
Two important reverse dipolar magnetic anomalies in the Iberian Chain (Spain) are located over Permian igneous rocks. A detailed study of one of them, the Loscos magnetic anomaly, where the geological structure is well constrained, reveals that the ...

Unrest at Domuyo Volcano, Argentina, Detected by Geophysical and Geodetic Data and Morphometric Analysis [PDF]

open access: yesRemote Sensing, 2019
New volcanic unrest has been detected in the Domuyo Volcanic Center (DVC), to the east of the Andes Southern Volcanic Zone in Argentina. To better understand this activity, we investigated new seismic monitoring data, gravimetric and magnetic campaign ...

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]

open access: yes, 2002
Results from equivalent-source distributions derived jointly from high-altitude (average 4 km) aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada indicate that long-wavelength components (500–2500 km) in these fields are ...

Crustal magnetization and long‐wavelength aeromagnetic anomalies of the Minto block, Quebec [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1999
Measured susceptibilities of >3500 samples from a 500×500 km area of the Minto block, Superior province, Quebec, have an average value of ∼0.03 SI (equivalent to induced magnetizations of ∼1.5 A/m). Charnockitic lithologies (igneous orthopyroxene‐bearing granodiorite, granite, diorite), that constitute large parts of the Minto region, yield the ...

The GPlates Portal: Cloud-Based Interactive 3D Visualization of Global Geophysical and Geological Data in a Web Browser. [PDF]

open access: yesPLoS ONE, 2016
The pace of scientific discovery is being transformed by the availability of 'big data' and open access, open source software tools. These innovations open up new avenues for how scientists communicate and share data and ideas with each other and with ...

Satellite mapping of the Antarctic gravity field

open access: yesAnnals of Geophysics, 1999
The production and analysis of the Antarctic digital magnetic anomaly map will be greatly aided by complementary gravity data. They help to constrain thickness variations of the crust and related magnetic effects that may be used for correcting long ...

Crustal xenolith magnetic properties and long wavelength anomaly source requirements

open access: yesGeophysical Research Letters, 1982
Granulite xenoliths, probable components of the lower continental crust, are a primary source of information about the magnetization of the lower crust. Magnetization values for lower crustal xenoliths from three tectonic settings (converging plate margin, rift valley, and continental intraplate region) demonstrate that metabasic rocks in the granulite

Magnetohydrodynamics of Chiral Relativistic Fluids [PDF]

open access: yes, 2015
We study the dynamics of a plasma of charged relativistic fermions at very high temperature $T\gg m$, where $m$ is the fermion mass, coupled to the electromagnetic field.

Rock magnetic properties of the Arunta Block, Central Australia, and their implication for the interpretation of long‐wavelength magnetic anomalies [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1993
Rock magnetic and petrologic studies of a suite of deep crustal rocks from the Arunta Block of Central Australia reveal that the granulite grade rocks are in general much more magnetic than the amphibolite grade samples irrespective of bulk rock composition.
