Exploration Geophysics Group ~ Geophysics Data Holdings

These pages contain information on all gravity, magnetic, radiometric, electro-magnetic (EM) and electrical (IP, resistivity) geophysical surveys data held by the Department of Mining.
The maps below show the full coverage of data holdings for each data type. The accompanying Data Catalogue lists each survey with information on where, when and who it was conducted by and what data is available. For further enquiries and requests for data please contact Nathan Mosusu or James Mokepwesi in the Geophysics group of the Geological Survey.
