Volcanic rock type uranium mine target optimization method based on element geochemical abnormity

Abstract

The invention relates to a volcanic rock type uranium mine target optimization method based on element geochemical abnormity. The method sequentially comprises steps of: 1), acquiring or collecting element geochemical data; 2), making a single-element geochemical abnormity graph; 3), carrying out mine point projection conversion; 4), indicating element screening; 5), making a thorium-to-uranium ratio geochemical equivalence graph; 6), making a uranium element, auxiliary indication element and thorium-to-uranium ratio geochemical abnormity graph and carrying out projection conversion; 7), determining an abnormity state; and 8), determining a grade of a uranium metallogenic distant-view target area. The volcanic rock type uranium mine target optimization method is suitable for multiple volcanic rock type metallogenic strips and prediction areas in the national scope, has properties of wide coverage scope, high efficiency, strong practicality and good accuracy, further has properties of clear indication elements, strong operationality and standard evaluation method flow, improves evaluation efficiency and guarantees objectivity of the research result.

Description

technical field [0001] The invention relates to a volcanic rock type uranium ore target selection method based on elemental geochemical anomalies, in particular to a volcanic rock type uranium ore target area optimization method suitable for volcanic rock 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. Uranium deposits in my country are mainly divided into four types, including granite type, volcanic rock type, sandstone type and carbon-silica mudstone type. Volcanic rock type uranium deposits are one of the most important types among the four types of uranium deposits in my country. In the evaluation of elemental geochemical anomalies In the work, in the...

Uranium deposits in my country are mainly divided into four types, including granite type, volcanic rock type, sandstone type and carbon-silica mudstone type. Volcanic rock type uranium deposits are one of the most important types among the four 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 method for volcanic rock-type uranium ore target selection
