Method for identifying and locating deep favorable ore-forming space of granite-type uranium mine

Abstract

The invention belongs to the technical field of geological exploration, and specifically relates to a method for identifying and locating a deep favorable ore-forming space of a granite-type uranium mine. The invention aims to provide a method for identifying and locating a deep favorable ore-forming space of a granite-type uranium mine so as to provide a basis for the delimitation of a uranium ore-forming favorable section of the granite-type uranium mine in allusion to the deficiencies of the prior art. The technical scheme of the invention comprises the steps of 1, deducing the deep uraniummineralization scale according to a geological method, and identifying a deep favorable ore-forming space; 2, deducing deep extension of known fault structures and buried fault structures by using anaudio magnetotelluric and high-precision magnetic measurement geophysical method, and detecting a deep favorable ore-forming space; 3, detecting deep uranium mineralization information by using a partial content geochemical exploration method and a soil thermoluminescence method, and providing identification information of the deep favorable ore-forming space; and 4, realizing identification andlocation for the deep favorable ore-forming space according to the identification in the step 1 for a deep ore-forming mark of the typical ore deposit by combining three-dimensional anatomy of the deep favorable ore-forming space and adopting location for the deep ore-forming environment according to audio magnetotelluric sounding and high-precision magnetic measurement in the step 2 and deep ore-forming information detected according to partial content geochemical exploration and soil thermoluminescence in the step 3.

Description

technical field [0001] The invention belongs to the technical field of geological exploration, and in particular relates to a method for identifying and locating a favorable ore-forming space in the deep part of a granite-type uranium deposit. Background technique [0002] Granite-type uranium deposits are one of the four types of uranium deposits in my country. After more than 50 years of uranium exploration in China, most of the shallow deposits have been discovered. At present, the focus of uranium exploration has shifted to deep ore prospecting. The favorable space for deep mineralization is buried underground, and the common surface identification marks are difficult to play a role, and the identification marks for deep favorable mineralization space are often not displayed on the surface, and the shallow favorable mineralization space does not necessarily extend too deep, so Establishing a set of favorable space identification and positioning technology suitable for de...
