The application of integration analysis of multi-geoscience information to the prospective prognosis of uranium deposits in Danfeng triangle area

The Danfeng triangle area is one of major uranium metallogenic belts in East Qinling region. At present, some pegmatite and hydrothermal uranium deposits have been discovered. The multi geoscience information are handled and studied synthetically by using aero magnetic survey, gravity survey, TM image, surface gamma-ray spectrometric survey and geological survey. After preliminarily summarizing the spatial distribution of Caledonian anatetic magmatic granite with relation to pegmatite-type uranium deposit and the combination pater of multi-geoscience information of the pegmatite-type uranium deposit, the prospective areas of uranium deposit are indicated
