Lesur, Vincent. 2002 Crustal susceptibility maps of the Earth lithosphere. [Poster] In: OIST-4, Copenhagen, Denmark, 23-27 September 2002. (Unpublished)
Abstract
We derive models of susceptibility of the crust. The crustal magnetization is modelled as a series of magnetic dipoles at the centres of triangles forming an almost regular tessellation of the Earth’s surface. The orientation of the dipoles is defined using a model of the core field calculated from satellite data. The susceptibility model is obtained by fitting the satellite data set with a main field subtracted. A regularization is introduced by minimizing a measure of the roughness in space of the susceptibility.
