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 in conjunction with the accompanying drawings and embodiments.

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

[0036] The structural location of the Binxian area is at the transitional position between the Yi-Shan slope and the Weibei uplift at the southern margin of the Ordos Basin. From top to bottom, the drill holes mainly revealed the Quaternary, Neogene, and Cretaceous Huanchi Huahe Formation, Luohe Formation, Yijun Formation, Jurassic Zhiluo Formation, Yan'an Formation, Fuping Formation ( figure 1 ). The lower member of the Zhiluo Formation is one of the main uranium-bearing strata in the Ordos Basin, with gray-green and yellow-brown medium-coarse-grained feldspar-quartz sandstone developed on the top, and gray-white, gray-green medium-thick, mas...

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 in particular relates to a method for predicting favorable sand bodies and favorable zones for sandstone-type uranium ore-forming. Background technique [0002] At present, my country is in a critical period of industrial structure transformation, "energy saving and emission reduction" is the top priority, the previous "extensive - high energy consumption" production mode will gradually be replaced by "clean - effective" production mode, nuclear power It is one of the best choices. my country is in a period of great development of nuclear power construction, and needs a large amount of natural uranium supply every year, and it increases year by year. This requires sufficient reserves of economically recoverable uranium resources to meet the needs of national nuclear power construction. Guaranteeing the stable supply of natural uranium resources in China has become a s...
