Embodiment Construction

[0024] A method for optimizing the in-situ U-Pb isotopic age of pitchblende micro-area provided by the present invention will be further described in detail below with reference to the accompanying drawings and specific examples.

[0025] Take the Zhangjia uranium deposit as an example, such as figure 1 As shown, a method for optimizing the in-situ U-Pb isotopic age of pitchblende micro-area provided by the present invention includes the following steps:

[0026] Step 1: Data Wrangling

[0027] The data provided by the laboratory through LA-ICP-MS in situ analysis were organized so that the U-Pb isotopic age of each point corresponds to the rare earth element data of the corresponding point, and the table shown in Table 1 was obtained, which is convenient for Comparative analysis.

[0028] Table 1 Data organization style (only part of the data is listed)

[0029]

[0030] Step 2: Data Calculation

[0031] Standardize the rare earth elements, that is, divide the correspo...

Abstract

The invention belongs to the technical field of isotope metallogenic age analysis, and in particular relates to an in-situ U-Pb isotope age optimization method for pitchblende micro-zones. Including the following steps: Step 1: Data collation; Step 2: Calculate LREE / HREE N ;step 3: plot age‑(LREE / HREE) N Ratio map; step 4: drawing rare earth distribution model map; step 5: data optimization, and weighted average processing, to obtain the age of uranium mineralization. The invention can accurately obtain the validity of the pitchblende U-Pb isotope age.

Description

technical field [0001] The invention belongs to the technical field of isotopic metallogenic age analysis, in particular to a method for optimizing the in-situ U-Pb isotopic age of pitchblende micro-area. Background technique [0002] Metallogenic age is one of the important contents in the study of mineral deposits, and it is one of the important parameters for in-depth study of the metallogenic geodynamic environment, the genesis of the deposit, and the degree of preservation after mineralization. For hydrothermal uranium deposits, the solution dilution method of pitchblende single mineral has been used for a long time, and its corresponding U and Pb isotopic compositions were obtained by thermal ionization mass spectrometry analysis, and then its apparent age was calculated. By processing the U and Pb isotopic composition data of multiple pitchblende single-mineral samples by correlating isochronous and concordant lines, the isochrone age and the intersection age of the i...
