Trend surface analysis is a type of multiple regression where point coordinates are independent variables and grade or thickness and… can be dependent variables. In this method, we fit a suitable surface to major values.
In this paper, we applied trend surface analysis to airborne geophysical data sets including the magnetic field intensity, resistivity (frequency= 4600 Hz) and radioactivity (Potassium counting). Results show the trend of these factors and their relations. Magnetic field intensity and resistivity have a similar trend despite the trend of Potassium counting.  Finally, the ability of this method in interpreting the same data has been acknowledged.
