The application of airborne geophysics data for rapid regional geological mapping in Northwestern Angola

Airborne prospecting (spectrum, magnetics) measurement is an effectively auxiliary approach for geological mapping. It effectively measures the magnetic field characteristics and the surface contents of the most common three radioactive elements (K,eU and eTh) of nature in the research area. Given t...
