Problems solved by technology

The favorable space for deep mineralization is buried deep underground, and common identification marks are difficult to play a role. The identification marks and positioning techniques that are feasible in shallow surface uranium ore prospecting may not be applicable to deep ore prospecting

Embodiment 1

[0040] The present invention will be further described in detail below by taking the alkali metasomatized uranium deposit in Kirovograd, Ukraine as an example.

[0041] Step 1: Based on previous research results, it is believed that there are various Precambrian uranium deposits in the Ukrainian Shield, including: i) uranium (thorium) deposits in conglomerate; ii) uranium controlled by fault zones Mineralized veins (experienced multiple phases of deformation since 2.1Ga); iii) thorium-uranium mineralization associated with potassium metasomatism; iv) uranium deposits associated with sodium metasomatism. However, the expansion of Ukrainian uranium resources largely depends on uranium deposits related to sodium replacement (such as sodium replacement type deposits) and thorium-uranium deposits related to potassium replacement. These deposits, although small and unfocused, have high extraction rates. Most uranium deposits are located in the Paleoproterozoic sodium metasomatite (...

Abstract

The invention belongs to the technical field of uranium ores, and particularly relates to a method for integrating deep mineralization information of an alkali metasomatism type uranium ore. The method comprises the steps of 1, building an ore finding model through a comprehensive mineralization theory research result; 2, building a geologic structure model by virtue of a comprehensive gravity exploration technology result; 3, processing a comprehensive deep earthquake detection result, and deducing an invasion direction and an activity area of mantle; 4, carrying out medium and large-scale soil radon gas and high-precision magnetic force measurement for horizontally delineating a radon gas anomaly and magnetic positive anomaly region; and 5, longitudinally delineating a radon gas, magnetic force anomaly and deep fracture overlapping region, namely, a deep ore finding target region.

Description

technical field [0001] The invention belongs to the technical field of uranium ore, and in particular relates to a method for integrating deep metallogenic information of alkali metasomatization uranium ore. Background technique [0002] Metallogenic information is comprehensively processed and predictive information that indicates or identifies a certain mineralization condition or occurrence mode of a certain ore deposit. It can be in the form of data, written data, or parameters after data processing, which is the basis of metallogenic prediction. Since the French scholar Langnet put forward the concept of "mineralization law", the field of metallogenic analysis has developed rapidly with the development of ore-prospecting practice. In the corresponding new stage, a large number of high-resolution and strong penetrating geology, geophysics, geochemistry, remote sensing and other prospecting methods and technologies have been continuously matured and applied, and at the s...
