TLDR
In this article, the authors estimate the Curie point depth (CPD) variations of Venezuela and the Eastern Caribbean by using spectral analysis of the magnetic anomalies extracted from the 2010 Enhanced Magnetic Model (EMM2010), available at the National Oceanic and Atmospheric Administration (NOAA).About:

Eight good reasons why the uppermost mantle could be magnetic
Eric C. Ferré,S. A. Friedman,Fátima Martín-Hernández,Joshua M. Feinberg,J. L. Till,Dmitri A. Ionov,James A. Conder +6 more
TL;DR: In this article, a collection of unaltered mantle xenoliths was found to contain pure magnetite inclusions in olivine and pyroxene formed in equilibrium with the host silicate.

Thermal Perturbations beneath the Incipient Okavango Rift Zone, Northwest Botswana
Khumo Leseane,Estella A. Atekwana,Kevin L. Mickus,Mohamed G. Abdelsalam,Elisha Shemang,Eliot A. Atekwana +5 more
TL;DR: In this article, the authors used aeromagnetic and gravity data to investigate the thermal structure beneath the incipient Okavango Rift Zone (ORZ) in northwestern Botswana in order to understand its role in strain localization during rift initiation.
Eight good reasons why the uppermost mantle could be magnetic
TL;DR: In this paper, it was shown that the uppermost mantle of the Earth contains pure magnetite inclusions in olivine and pyroxene formed in equilibrium with the host silicate.
Journal ArticleDOI
Depth to the bottom of magnetic layer in South America and its relationship to Curie isotherm, Moho depth and seismicity behavior
TL;DR: In this article, the authors estimated the depth to the bottom of the magnetic layer (DBML) in South America from the inversion of magnetic anomaly data extracted from the EMAG2 grid.

Geothermal data analysis at the high-temperature hydrothermal area in Western Sichuan
TL;DR: In this article, the authors used gravity, magnetic, seismic, and helium isotope data to analyze the crust-mantle heat flow ratio and deep geothermal structure of the western Sichuan hydrothermal area, which is also the eastern end of the Mediterranean-Himalayan geothermal activity zone.

Statistical models for interpreting aeromagnetic data
A. Spector,F. S. Grant +1 more
TL;DR: In this article, a mathematical basis for the application of power spectrum analysis to aeromagnetic map interpretation is developed and an ensemble of blocks of varying depth, width, thickness, and magnetization is considered as a statistical model.

Heat flow from the Earth's interior: Analysis of the global data set
TL;DR: In this paper, a new estimate of the Earth's heat loss based on a new global compilation of heat flow measurements comprising 24,774 observations at 20,201 sites is presented, which when areally weighted yield a global mean of 87 mW m -2 and a global heat loss of 44.2 x 10 2 W, an increase of some 4-8% over earlier estimates.
Journal ArticleDOI
Latest pulse of Earth: Evidence for a mid-Cretaceous superplume
TL;DR: For the past 150 m.y. as mentioned in this paper, a 50% to 75% increase in ocean crust formation rate between 120 and 80 Ma was seen both in spreading-rate increases from ocean ridges and in the age distribution of oceanic plateaus.
Journal ArticleDOI
Thermal structure of oceanic and continental lithosphere
TL;DR: In this article, the authors re-examine the thermal models of both oceans and shields and show that radiogenic heating is not as concentrated at shallow depths as was previously believed, and take account of both these effects and the temperature dependence of the thermal conductivity increases the Moho temperatures.

TL;DR: In this article, a global Earth Magnetic Anomaly Grid (EMAG2) has been compiled from satellite, ship, and airborne magnetic measurements, both over land and the oceans, where the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids.
