Carbonaceous-siliceous-argillitic rock type uranium deposit target region optimization method based on elemental geochemical anomaly

Abstract

The invention relates to a carbonaceous-siliceous-argillitic rock type uranium deposit target region optimization method based on elemental geochemical anomaly, comprising the following steps: 1) acquisition or collection of elemental geochemical data; 2) compilation of a single elemental geochemical anomaly chart; 3) ore spot projection transformation; 4) indicator element screening; 5) compilation of uranium (uranium is selected in granite-exposed areas) and ancillary indicator element geochemical anomaly charts and projection transformation; 6) judgment of abnormal forms; and 7) judgment of the level of uranium metallogenic prospect target regions. The method is suitable for multiple carbonaceous-siliceous-argillitic rock type metallogenic belts and predication areas nationwide, and has advantages of wide coverage, high effectiveness, high applicability and good accuracy. The method has clear indicator elements and has high operationality. Evaluation methodology procedures are standardized; evaluation efficiency is raised; and objectivity of research results is guaranteed.

Description

technical field [0001] The present invention relates to a method for selecting a carbon-silicon mudstone-type uranium ore target area based on elemental geochemical anomalies, in particular to a carbon-silicon-silicon mudstone-type uranium ore resource potential evaluation and uranium ore prospect target area prediction method Uranium ore target optimization method. Background technique [0002] Elemental geochemical method is an important and effective method for geochemical prospecting of uranium ore. This method evaluates and predicts 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, carbon-silicon mudstone type and carbon-silicon mudstone type. Carbon-silicon mudstone-type uranium deposits are one of the most important types among the four major types of uranium deposits in my cou...

Uranium deposits in my country are mainly divided into four types, including granite type, volcanic rock type, carbon-silicon mudstone type and carbon-silicon mudstone type. Carbon-silicon mudstone-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 geochemical anomalies, in the past, there were no clear indicator elements and their screening methods 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 quality of uranium deposits. Therefore, it is urgent to provide a new target selection method for carbon-silica mudstone-type uranium deposits.
