Abstract

Based on the survey of soil radon gas and gamma spectrum in the Michurinskoye uranium deposit in Central Ukrainian U province, and the comprehensive comparative analysis of the existing regional gravity, magnetic, seismic and logging data, the authors used various geophysical exploration techniques to evaluate the existing orebodies rapidly and effectively. On the basis of the analysis and study of ore-controlling structures in tectonic alteration zones, the authors constructed the identification technology of deep uranium metallogenic information and the comprehensive technology of deep uranium resources exploration and evaluation for hydrothermal uranium deposits, and provided theoretical guidance for the prospecting of alternative resources in similar mining areas and crisis mines.

Key words： soil radon γ spectrum; gravity and magnetism ore-controlling structure Ukraine Michurinskoye uranium deposit
