Sandstone-type uranium mine target region optimal selection method based on element geochemical anomaly

Abstract

The invention relates to a sandstone-type uranium mine target region optimal selection method based on element geochemical anomaly. The method successively comprises the following steps: 1) element geochemical data is acquired or collected; 2) a single element geochemical anomaly map is established; 3) the mineral occurrence projection transformation process is performed; 4) the indicator element screening process is performed; 5) uranium element and auxiliary indicator element geochemical anomaly maps are established and the projection transformation process is performed; 6) and the level of an uranium metallogenic prospect target region is judged. The method of the invention is suitable for a plurality of sandstone-type metallogenic belts and forecast regions on a national scale, and advantages of wide coverage, high effectiveness, good applicability and good accuracy can be realized. According to the invention, the indicator elements are clear, the advantage of good operability can be realized, the method process is evaluated normatively, the evaluation efficiency is improved, and the objectivity of the study result can be ensured.

Description

technical field [0001] The invention relates to a sandstone-type uranium ore target area optimization method based on elemental geochemical anomalies, in particular to a sandstone-type uranium ore target area optimization method suitable for sandstone-type resource potential evaluation and uranium prospect target area prediction. Background technique [0002] Elemental geochemical method is an important and effective method for geochemical prospecting of uranium ore. This method evaluates the ore-forming potential of uranium ore through the abnormal content of ore-forming elements and associated elements in the region. my country's uranium deposits are mainly divided into four types, including granite type, volcanic rock type, sandstone type and carbon-silica mudstone type. Sandstone type uranium deposits are one of the most important types among the four major types of uranium deposits in my country. In the evaluation of elemental geochemical anomalies In the work, in the pa...

my country's uranium deposits are mainly divided into four types, including granite type, volcanic rock type, sandstone type and carbon-silica mudstone type. Sandstone type uranium deposits are one of the most important types among the four major types of uranium deposits in my country. In the evaluation of elemental geochemical anomalies In the work, in the past, there was no clear indicator element and its screening method for ore prospecting, and there was no clear method for selecting uranium ore-forming target areas based on geochemical anomalies, which directly affected the utilization level of geochemical data and the effect of uranium ore potential evaluation , so it is urgent to provide a new type of sandstone-type uranium ore target optimization method
