Embodiment

[0052] The present invention will be further described in detail below by taking the location identification of the Jiangxi Xiangshan uranium mine in the hotspot action zone as an example.

[0053] Step 1: Collect basic geological data in South China and conduct comprehensive analysis to determine the geological background and corresponding range of hotspot action areas.

[0054] South China South China is located at the southeastern end of the Eurasian continent. It is the junction zone between the Eurasian plate and the Pacific plate. After the Indosinian and Yanshan orogenic movements, this area has been in a strong extensional environment, resulting in a cracked structural weak zone; regionally accompanied by various The intrusion of dikes and the development of basin deposits, especially the red basin construction continued.

[0055] The geological interpretation of remote sensing images in South China shows that in the border area of ​​Hunan, Jiangxi, and Guangdong provi...

Abstract

The present invention belongs to the uranium geology and resource evaluation technology field, in particular to a method of positioning the uranium deposits rapidly and effectively in a hot spot active region. The method comprises the following steps of 1 determining a hot spot active region range and a geological background; 2 screening and positioning a uranium mineralization favorable area in the hot spot active region; 3 screening and positioning a key section in a favorable metallogenic region; 4 determining a uranium mineralization environment in the key section; 5 integrating the metallogenic information and predicting the mineralization; 6 drilling and verifying in the key section. A uranium deposit and ore body positioning technology of the present invention is based on a brand new hot spot uranium mineralization theory and a prediction method and combines the geology, geophysics and geochemistry features to carry out the regional mineralization prediction and positioning on the basis of fully mining the previous data, and an operation method is simple and convenient and is high in accuracy, the prediction blindness is reduced, and the evaluation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of uranium ore geology and resource evaluation, and in particular relates to a method for accurately and quickly locating uranium ore in hot spot action areas. Background technique [0002] With the transformation of China's production capacity structure, the use of "clean, safe and efficient" energy will be the mainstream of future development, and nuclear power has become an important development field for optimizing the energy structure. The rapid development of my country's nuclear industry has put forward a long-term and important demand for uranium resources, but the existing uranium resources can only guarantee the short-term demand, and there will be a large gap in the long-term supply, making the uranium ore prospecting work more and more urgent. The application of new metallogenic theory and exploration methods can provide new ideas for uranium ore prospecting and achieve better results. In recent...
