چکیده:

In the primal stages of Uranium exploration, the main stage, is to use the airborne geophysics data taken by means of flights of airplanes containing gamma ray detectors. The results of these acquisitions, are the digital data and contour maps of radiometry. attention to distribution of Uranium element in the earth crust and study of these maps, the main parts of first stage of Uranium exploration are the factors and methods of sepaqration of boundaries and hot points of anomaly from background parts. In this paper, in the first method separation of anomaly values is done by means of classic statistics and by calculations of statistical parameres that criterion of this separation is based on the amounts of around of average. In the second method, separation of anomaly values is done by means of fractal geometry. In the fractal method. Separation has done by use of curve of concentration- area. At the end, the maps of anomaly introduction and mine index of Uranium are prepared to continue the exploration work.
