Curie Point Depths Based on Spectrum Analysis of Aeromagnetic Data, West Anatolian Extensional Province, Turkey

open access: yesPure and Applied Geophysics, 2005
The Curie point depth map of Western Anatolia was constituted from spectral analysis of the aeromagnetic data. The Curie point depth values from 53 overlapping blocks, 90 × 90 km in size, have been estimated from the band-pass filtered data. The slope of the longest wavelength part of the radially averaged log power spectrum divided by the radial ...

Curie Point Depth Investigation of Central Anatolia, Turkey

Pure and Applied Geophysics, 2005
The residual aeromagnetic total field intensity anomalies in central Anatolia were calculated from the regional aeromagnetic anomalies surveyed by the Mineral Research and Exploration (MTA) of Turkey. The residual aeromagnetic data were analyzed to produce Curie point estimates by the method of OKUBO et al. (1985).

Thermal Structure of the Icelandic Crust From Curie Point Depth

open access: yesJournal of Geophysical Research: Solid Earth
Abstract We present a Curie point depth map that casts light on the deep crustal thermal structure and contributes to understanding the mechanisms of Iceland's formation. Using high‐precision aeromagnetic anomaly data and a fractal magnetization model, we estimate Curie point depths ranging from 4 to 30 km.

Curie Point Depths of Macedonia and Thrace, N. Greece

Pure and Applied Geophysics, 2002
— The aeromagnetic data of Macedonia and Thrace were used to produce Curie point estimates. The data were high pass filtered to remove components arising from topography and magnetic core fields which were not adequately modeled by a DGRF. The depth to the centroid, z 0, of the deepest distribution of the magnetic dipoles was ...

Curie point depth in Venezuela and the Eastern Caribbean

Tectonophysics, 2013
Abstract We estimate the Curie point depth (CPD) variations of Venezuela (continental crust, South American plate) and the Eastern Caribbean (oceanic crust, Caribbean Plate) by using spectral analysis of the magnetic anomalies, extracted from the 2010 Enhanced Magnetic Model (EMM2010), available at the National Oceanic and Atmospheric Administration (

Curie point depths in Northeast China and their geothermal implications for the Songliao Basin

Journal of Asian Earth Sciences, 2018
Abstract This work integrates processing and interpretation of the combined geomagnetic anomaly model of NGDC-720-V3.1 to better constrain thermal structures of the Northeast China lithosphere, which shows intensive extension and active volcanism during the Mesozoic and Cenozoic. Numerical tests demonstrate that magnetic anomalies calculated at 20 km

Curie Point Depths of Albania Inferred from Ground Total Field Magnetic Data

Surveys in Geophysics, 2005
Ground total magnetic field data of Albania were used to produce estimates of the Curie point isotherm. The strategy followed was to estimate the depth to the bottom of the deepest magnetic sources. Firstly, the average depth to the top of the deepest crustal block, z t, was computed by linear fitting to the second lowest ...

Curie point depth from spectral analysis of aeromagnetic data for geothermal reconnaissance in Afghanistan

Journal of African Earth Sciences, 2015
Abstract The geologic setting of Afghanistan has the potential to contain significant mineral, petroleum and geothermal resources. However, much of the country's potential remains unknown due to limited exploration surveys. Here, we present countrywide aeromagnetic data to estimate the Curie point depth (CPD) and to evaluate the geothermal ...
