Description
Technical Field
The invention belongs to the technical field of geological exploration, and particularly relates to an element geochemistry method for identifying the center of a sodium-assisted uranium deposit ore body.
Background
The sodium-handed uranium deposit is a very important type of hydrothermal uranium deposit produced in ukraine, australia, canada, brazil, karilong, magas, usa, caragana, czech, etc.
Although the average grade of uranium of the sodium cross-substitution type uranium deposit is much lower than that of other types of uranium deposits, the content of uranium resources can be comparable with that of globally known non-integrated surface type uranium deposits, a large-scale uranium mineralization zone is formed, and the uranium mineralization zone has a good prospect of prospecting.
The sodium-mixed uranium deposit is relatively developed in a uranium mineralization zone from Qilian mountain to Longshou mountain in China, such as splendid achnatherum, a new water well, a Bandu mouth and the like. However, the ore deposit discovered in China at present is small in scale and complex in ore body form, so that the deep mineralization potential of the existing sodium alternate uranium ore deposit is difficult to accurately determine, and the exploration result is difficult to break through.
Due to the influence of the multiple stages and sources of the mineralization process and the distribution and migration rules of elements in the geologic body, geochemical elements in the mineralization area show the characteristics of symbiotic combination halo in space.
Therefore, research on an element geochemical method for identifying the ore body center of the sodium-substitution uranium deposit is developed so as to rapidly and objectively evaluate the deep mineralization potential of the existing sodium-substitution uranium deposit, thereby achieving the purpose of effectively and economically solving the geological problem and obtaining a good ore finding effect.

By analyzing the change rule of the content of various trace elements on the space, the characteristic element combination halos in different mineralization zones are counted, so that the halos are used for predicting and distinguishing the center of the sodium-substitution uranium deposit ore body.
The analysis result is as follows:
within seventy-eighty meters above the sodium-substituted uranium ore body, obvious U, Th, Y, V and Pb compound halos exist, the scale of the U, Th and V halos is similar to or larger than that of the ore body, the scale of Y, Pb is small, and the distribution is sporadic; the Y, Pb part where the ore body is located is increased in scale, the strength is increased, the V-shaped halo is increased along with the depth, the strength is reduced, the scale is reduced, and Co-shaped halo appears; the Y, V, Pb halos became smaller and the Co halos became larger in size at the root and below of the ore than the U halos.
