Embodiment 1

[0054] Embodiment 1 The preferred application example of the sandstone-type uranium metallogenic prospect area in the strong structural deformation area of ​​the southern margin of the Junggar Basin The specific steps for the optimization of the sandstone-type uranium metallogenic prospect area in the strong structural deformation area of ​​the southern margin of the Junggar Basin using the method of the present invention are as follows:

[0055] (1) Identification of remote sensing alteration information

[0056] The vegetation coverage in the southern margin of the Junggar Basin is very weak, and the aerial hyperspectral remote sensing data can be interpreted to extract the iron-stained alteration information related to sandstone-type uranium mineralization and circled in the figure, such as figure 2 shown.

[0057] (2) Delineate the distribution range of favorable sand bodies for uranium mineralization

[0058] The spatial distribution range of the main channel sand bodie...

Abstract

The invention belongs to the field of uranium ore mineralization theory and ore prospecting technical methods, and particularly relates to an ore prospecting technical method for sandstone-type uranium ores in a competent structure deformation area. The ore prospecting technical method comprises the following steps that (1) remote sensing alteration information is recognized; (2) the uranium mineralization favorable sand body distribution range is delineated; (3) a structure favorable section is delineated; (4) the uranium mineralization potential is evaluated; and (5) a uranium mineralizationprospective area is optimized. The ore prospecting technical method has the beneficial effects that the technical method can be provided for finding the sandstone-type uranium ores in the competent structure deformation area, thus ore prospecting in the competent structure deformation area has better intentionality and pertinence, and blind investment is reduced.

Description

technical field [0001] The invention belongs to the field of uranium mineralization theory and prospecting methods, and particularly relates to a prospecting method for sandstone-type uranium deposits in strong structural deformation areas. Background technique [0002] Among the many ore-controlling factors of sandstone-type uranium deposits, the strength of tectonic deformation has always been the key factor restricting the mineralization and ore body preservation of sandstone-type uranium deposits. Especially after the formation of the uranium ore body, it is easily affected by the later structural uplifting and denudation. Therefore, most of the world's sandstone-type uranium deposits are located in areas with weak structures, namely "sub-orogenic areas". However, with the gradual advancement of the exploration of sandstone-type uranium deposits in my country, sandstone-type uranium deposits have been discovered in strong tectonic deformation areas. model. [0003] The...
