Embodiment Construction

[0033] A method for rapid area selection for early exploration of sandstone-type uranium deposits provided by the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0034] Utilizing the technical solution of the present invention, taking the early rapid selection of sandstone-type uranium deposit exploration in the northern part of the southwestern margin of the Ordos Basin as an example, the method of the present invention is further specifically described:

[0035] Step 1 Collect and sort out previous research results and regional geological data on the southwestern margin of the Ordos Basin, analyze the uranium content of the erosion source area of ​​the basin, and clarify the distribution range of the uranium-rich basement and rock mass at the edge of the basin.

[0036] Step 1.1 Systematically collect the research results and exploration results of the southwestern margin of the Ordos Basin, as well as the existi...

Abstract

The invention belongs to the field of sandstone-type uranium ore favorable zone prediction technology research, and particularly relates to a sandstone-type uranium ore early exploration rapid selection method. The method comprises the steps of 1, collecting and arranging research results and regional geological data of a working area, and defining a basin edge uranium-enriched basement and a rockmass distribution range; 2, determining stratum characteristics and uranium-bearing property of the working area, and determining a main ore-bearing target stratum; carrying out favorable sedimentaryfacies belt distribution characteristic research, and accurately positioning the spatial range of favorable mineralization lithology-lithofacies belt; 3, defining a favorable uranium mineralization age, defining ancient landform characteristics of a favorable mineralization period of an ore-bearing target stratum, and defining the distribution position of a sandstone type confluence channel in the working area; and 4, quickly selecting a favorable exploration area.

Description

technical field [0001] The invention belongs to the research field of sandstone-type uranium ore favorable zone prediction technology, and in particular relates to a method for rapid area selection for early-stage exploration of sandstone-type uranium ore. Background technique [0002] The rapid development of nuclear power in my country in the new period puts forward new requirements for the exploration and development of uranium resources. At present, my country's uranium resource reserves and existing economically recoverable uranium resources are limited. It is necessary to increase scientific research investment in uranium resource detection, integrate prediction methods and use advanced information technology to find new uranium resources. Sandstone-type uranium deposits will become an important part of nuclear energy resources in the future, with the characteristics of large ore volume, low cost, and low mining pollution. [0003] Since the 1990s, my country has made...
