Embodiment

[0034] The present invention will be further described in detail below by taking the white granite-type uranium deposit in the Happy Valley area of ​​Namibia as an example.

[0035] Step 1: Carry out field investigation in the Happy Valley area of ​​Namibia, and collect uranium mineralized white granite samples purposefully. The samples are required to be fresh, generally 3×6×9cm.

[0036] Step 2: Rock ore identification and electronic probe analysis of the collected uranium-mineralized white granite. Firstly, light thin sections are made of the collected mineralized white granite with a thickness of about 0.3mm. The uranium mineral composition of the ore is observed on a microscope, and the uranium minerals with a particle size larger than 50μm are circled. Then, according to GB / T15074- 2008 "General Rules for Quantitative Analysis Methods of Electron Probe", JXA-8100 electronic probe analyzer is used to analyze the chemical composition of uranium minerals, so as to determine...

Abstract

The invention belongs to the technical field of uranium ore, and specifically relates to a method for testing the formation age of crystalline uranium ore; The age of uranium deposits and the role of metallogenic evolution analysis, decomposing the key elements and main ore-controlling factors of each metallogenic period from complex geological phenomena, providing ideas for uranium deposit exploration, and guiding specific ore-prospecting work to test crystal quality The method for the formation age of uranium ore; including the following steps: Step 1, field investigation and collection of uranium ore samples; Step 2, rock ore identification and electronic probe analysis on the ore samples; Step 3, using LA-ICP-MS Micro-zone dating of crystalline uranium ore; step 4, data collation, parameter calculation and mapping, and finally the formation age of uranium ore is obtained.

Description

technical field [0001] The invention belongs to the technical field of uranium ore, in particular to a method for testing the formation age of crystalline uranium ore. Background technique [0002] At present, the research methods of the chronology of uranium deposits mainly include: (1) The isotope dilution TIMS method is used to measure uranium minerals such as crystalline uranium ore, and the ore-forming age is fitted by the U-Pb isochrone method. (2) Uranium ore is used instead of uranium minerals to determine the ore-forming age of the ore deposit, which greatly reduces the workload of sample preparation in the early stage. The theoretical basis is that the U and Pb isotopes in the uranium ore have reached uniformity since the evolution of uranium ore. However, the degree of isotope uniformity needs to be studied, and as a result, there are often large deviations in actual measurements. (3) Gangue minerals such as pyrite and galena, which coexist with uranium minerals,...
