Problems solved by technology

Due to the inability to effectively narrow the scope of work in the selection of the target area in the early stage, the work investment and low efficiency brought about by the wide scope of work will cause a series of "complications" problems, and the blind construction of Gannan drilling will not only increase the cost input, It also brings some disturbance to the environment

Embodiment Construction

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] The following is an example of the rare earth mining area in Hanfang, south of Gansu Province.

[0020] (1) Data collection and analysis

[0021] Metallogenic geological background: The Hanfang area is located in the Xiawentan complex pluton in the middle of the South China fold system in the central and southern Jiangxi folds and the Xinfeng-Yudu folds in the southwestern Jiangxi depression...

Abstract

The invention discloses an ion adsorption type rare earth ore exploration method which comprises the following steps: collecting a data analysis area metallogenic geological background and metallogenic conditions, and preliminarily determining a working area range; hydrogeological survey is carried out according to a certain proportional scale in the working area range, and the distribution area and type of water in the working area range are found out in detail; water geochemical samples are collected in the working area according to a certain net degree; performing rare earth element chemical analysis on the collected water geochemical sample; tracing an ion adsorption type rare earth mineralization abnormal source area according to a rare earth element chemical analysis result, and rapidly delineating a target area. According to the method, on the basis of hydrogeological survey, the rare earth element content of water is measured, then the mineralization abnormal source area is traced, the target area is rapidly delineated, the working range is effectively narrowed, the working investment is reduced, environmental disturbance caused by blind construction of Gannan drills is avoided, and a reliable basis is provided for delineation of the ion adsorption type rare earth target area.

Description

technical field [0001] The invention belongs to the field of geological mineral exploration, in particular to an ion adsorption type rare earth mineral exploration method. Background technique [0002] Ion adsorption type rare earth ore refers to rare earth deposits in which rare earth elements exist in the rock weathering crust in the form of exchangeable adsorbed cations. At present, the exploration of this type of ore deposit mostly adopts geological survey and southern Jiangxi drilling for sampling and analysis. Although this method can achieve a good prospecting effect, it also has some shortcomings. Due to the inability to effectively narrow the scope of work in the selection of the target area in the early stage, the large work investment and low efficiency brought about by the wide scope of work have caused a series of "complications" problems, and the blind construction of Gannan drilling will not only increase the cost investment, It also brings some disturbance t...
