Abstract

The invention belongs to the technical field of uranium ore geological exploration, and particularly relates to a method for quantitatively characterizing the tectonic uplift rate and the ore-forming favorable degree of sandstone type uranium ore. The method comprises the following steps: step 1, determining a uranium mine point / bed position in a region; 2, determining the horizon of each uranium ore point / bed; 3, determining uranium mineralization time of each uranium ore point / bed; 4, the tectonic uplift rate of the uranium metallogenic period is determined; and 5, evaluating the favorable degree of sandstone type uranium mineralization. According to the method, the control effect of structural augmentation on sandstone type uranium mineralization can be effectively and accurately reflected, and important evaluation parameters are provided for uranium mine potential and prospective area evaluation of sandstone type uranium mines, so that the exploration efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of uranium ore geological exploration, and in particular relates to a method for quantitatively characterizing the structural uplift rate and the favorable degree of ore-forming of sandstone-type uranium deposits. Background technique [0002] The activity of uranium determines the importance of structural uplift rate, especially the structural uplift rate during the uranium mineralization period. It is generally believed that relatively stable regional tectonic background and moderate (medium-intensity) structural uplift intensity / rate are favorable for the mineralization of sandstone-type uranium deposits. However, at present, the evaluation of the potential of sandstone-type uranium deposits is mainly guided by the qualitative description of tectonic activities, which greatly increases the uncertainty of ore prospecting. Therefore, the establishment of a method to quantitatively characterize the rate of ...
