Airborne surveys are used predominantly for exploration of ore minerals, but can also be applied for fossil fuels and geothermal exploration, and in various engineering, land management and mapping projects. The technique measures physical parameters such as: rock density contrasts (gravity gradiometry), electrical conductivity (electromagnetic systems), radioelement concentration (Gamma-spectrometry), and percentage of magnetite (magnetics).

Planning Your Summer Geological Field Work Program
