Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art that in the non-closed system, the ore-forming age of the uranium deposit cannot be accurately obtained by using traditional means, and the dating of the uranium deposit cannot be selected out of single uranium minerals, and to provide a radioactive genesis method under the non-closed system. The method of determining the metallogenic age of anomalous lead starts from the lead-free minerals that are easier to obtain lead isotopic composition data, and accurately determines the uranium deposits based on the systematic study of the lead isotopic composition characteristics, source identification, and evolution model of uranium-bearing minerals in uranium deposits. metallogenic age

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, the present invention provides a method for determining the metallogenic age of radioactive abnormal lead in a non-closed system, and the method includes the following steps:

[0038] Step (1), select high-purity lead-free single mineral

[0039] When collecting non-polluted and unweathered uranium ore samples in the field, drill core samples are the first choice. This sample should contain a sufficient amount of lead-free single minerals that are co-associated with uranium minerals. Pyrite and chalcopyrite are preferred. and other types of single minerals. The sample weight is generally not less than 2kg. If the target single mineral content is low, the sample weight should be increased accordingly. The number of samples should be more than 5, the sampling locations should be separated in space, and the ur...

Abstract

The invention belongs to the field of uranium mine geological exploration, and particularly relates to a method for determining mineralization age of radioactive cause abnormal lead in a non-closed system. The method comprises the following steps: selecting high-purity lead-free monominerals; determining the lead isotope composition; judging a two-stage evolution lead isotope system; determining the age of a uranium source layer; calculating uranium mineralization age. According to the method disclosed by the invention, the mineralization age of the uranium deposit is accurately determined onthe basis of systematically researching the composition characteristics, source discrimination, evolution mode and the like of the lead isotope in the uranium deposit uranium-containing mineral from the lead-free mineral of which the lead isotope composition data is easier to obtain.

Description

technical field [0001] The invention belongs to the field of geological prospecting of uranium deposits, and in particular relates to a method for determining the metallogenic age of abnormal lead of radioactive origin in a non-closed system. Background technique [0002] The determination of the metallogenic age of uranium deposits is an important part of the research on the genesis and metallogenic laws of uranium deposits, and is the basic content of uranium deposit research. Whether ore-forming age can be accurately determined will affect the establishment of ore deposit genetic model and prospecting model, and then affect the results of ore prospecting and exploration. [0003] The determination of the metallogenic age of uranium deposits is a worldwide problem. The existing methods and means for determining the metallogenic age are basically based on the closed evolution of the radioisotope system. Theoretically speaking, uranium minerals such as pitchblende in uraniu...
