... idealized model data and/or real data where the correct interpretation is uncertain. In this paper we propose a new approach for evaluating the effectiveness of ''depth to magnetic basement'' estimators. We present inversion results for a model magnetic dataset generated from a modified topography dataset...

... with current seismic techniques. A nonlinear 3D inversion modeling of corrected magnetic and decreased gravity data is also used to determine the depth to basement and the Infracambrian Hormuz salts over two regions. Our findings demonstrate that the depth to basement in these regions changes from 7100 to 9700...

... The Earth’s magnetic field, after core correction, is dominated by anomalies produced between crystalline basement and Curie point depth horizons, or The Magnetic Layer (TML). Motivated by the idea that Curie point depth is also a temperature horizon (∼580°C where cooling iron becomes magnetic...
