Granite-type uranium mine deep mineralization information extracting method

Abstract

The invention belongs to the technical field of uranium resource exploration, and discloses a granite-type uranium mine deep mineralization information extracting method. The method includes the following steps that: the geological units of a work area are defined according to different lithological features or strata; soil sampling is performed in the geological units; clay adsorbed state uraniumcontent and total uranium amount of soil samples in the geological units are analyzed; the ratio R of the clay adsorbed state uranium content to total uranium amount of the soil samples in the geological units is calculated according to the clay adsorbed state uranium content and total uranium amount of the soil samples; the abnormal lower limit C of the R value of the samples of the geological units is calculated; the ratio F of the R value of the samples of the geological units to the abnormal lower limit C is solved according to the R value and the abnormal lower limit C; with a constant 1adopted as the abnormal lower limit, the abnormal area of the F value of the work area is delimited, and a prospecting target area is determined for deep uranium mine exploration, and uranium mine deep mineralization information extraction is completed. With the method adopted, the interference of near-surface information can be greatly reduced, and deep uranium mineralization information can beeffectively extracted.

Description

technical field [0001] The invention belongs to the technical field of uranium resource exploration, and in particular relates to a method for extracting deep mineralization information of granite-type uranium deposits. Background technique [0002] The active forms of ions or particles produced by deep concealed ore bodies can migrate to the near-surface under the action of various geological forces such as geo-flow, and enrich in the near-surface overburden, forming epigenetic superposition anomalies. Although the element content of this active form is relatively low, it represents the direct information of deep mineralization and has important prospecting significance. Therefore, the extraction and analysis of the element content in the active form (measurement of the active state of the element) has become the current exploration of the earth. One of the hotspots of chemical research. The active state of elements can be divided into four phase states: water extraction p...

However, there are two factors that affect the application effect of the element activity measurement method, which are ignored by most researchers: first, the element activity in the surface cover layer not only comes from the deep, but also partly is the product of in situ material weathering; The second is the difference in the active state content of elements in different geological units (different lithology or strata); these two factors have a particularly prominent impact on the measurement results of active states of elements in southern my country
