Problems solved by technology

This method needs to use a large amount of drilling data, aerial data, ground radioactivity measurement data and seismic data to make all-round comprehensive prediction of favorable mineralization areas, and is suitable for the middle and late stages of exploration; but in the early stage of exploration, drilling data is relatively small , less radioactive measurement work, lack of seismic data, this method is not very applicable, and there is an urgent need for a prediction method for favorable zones of sandstone-type uranium deposits that is suitable for early uranium exploration work

Embodiment Construction

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0035] Taking the Binxian area as an example, a method for predicting favorable sand bodies and favorable zones for sandstone-type uranium deposits provided by the present invention is described in detail.

[0036] The tectonic location of Binxian area is located at the transition between the Yishan slope and the Weibei uplift in the southern margin of the Ordos Basin. From top to bottom, the drilling mainly exposed the Quaternary, Neogene, Cretaceous Huanchihuahe Formation, Luohe Formation, Yijun Formation, Jurassic Zhiluo Formation, Yan'an Formation, Fuping Formation and other strata ( figure 1 ). The lower member of Zhiluo Formation is one of the main uranium-bearing horizons in the Ordos Basin. The top of it is gray-green and yellow-brown medium-coarse-grained feldspar quartz sandstone, and the lower part is gray-white, gray-green medium-th...

Abstract

The invention, which belongs to the technical field of uranium ore geological research, specifically discloses a prediction method of a favorable sand body and a favorable zone of sandstone type uranium ore. The method comprises the following steps: step 1, carrying out ancient landform restoration; step 2, carrying out ancient landform division; and step 3, predicting a favorable sand body and afavorable zone of uranium ore. With the method provided by the invention, the favorable zone of the sandstone type uranium ore is determined by restoring an ancient landform of the ore target stratumdepositional stage and the uranium ore formation key period.

Description

technical field [0001] The invention belongs to the technical field of uranium ore geological research, and particularly relates to a method for predicting favorable sand bodies and favorable zones for sandstone-type uranium mineralization. Background technique [0002] At present, my country is in a critical period of industrial structure transformation, and "energy saving and emission reduction" is the top priority. The previous "extensive-high energy-consuming" production methods will gradually be replaced by "clean-effective" production methods. is one of the best options. my country is in a period of great development of nuclear power construction, and a large amount of natural uranium supply is needed every year, and it is increasing year by year. This requires sufficient reserves of economically mineable uranium resources to meet the needs of national nuclear power construction. Guaranteeing the stable supply of domestic natural uranium resources is a serious challen...
