3D susceptibility distribution model derived from 2010 BGR magnetic survey of the Mesa Range in northern Victoria Land, East Antarctica
We present a 3D crustal model of susceptibility distribution in the Messa Range in northern Victoria Land, East Antarctica. The inversion is based on airborne magnetic data with a line spacing of 500m conducted by the Federal Institute for Geosciences and Natural Resources (BGR) in 2010.
The inverted susceptibility allows to discriminate the three dominant rock types in the area namely Kirkpatrick Basalt, Ferrar rock and Granit Harbour intrusive.
We provide three netCDF files, which include the input magnetic data, the inverted magnetic field, and inverted crustal susceptibility distribution.
Funding for this research was provided by NERC through a SENSE CDT studentship (NE/T00939X/1)
