Semi-quantitative estimation method for denuded level of granite type uranium ore

Abstract

The invention belongs to the field of solid mineral exploration and specifically discloses a semi-quantitative estimation method for a denuded level of a granite type uranium ore. The method comprisesthe following steps: 1) estimating mineralizing depth of a uranium ore deposit; 2) estimating denudation depth of granite; 3) estimating the denudation level of uranium ore in the granite according to the mineralizing depth of uranium ore deposit estimated in the step 1) and the denudation depth of granite estimated in the step 2). The method disclosed by the invention is capable of scientifically evaluating the deep mineral exploration space of the granite type uranium ore and promoting the quick breakthrough for the deep uranium resource of the granite type uranium ore.

Description

technical field [0001] The invention belongs to the field of solid mineral exploration, and in particular relates to a semi-quantitative estimation method for denudation depth of granite-type uranium deposits based on the study of fluid inclusions in granite-type hydrothermal uranium deposits and the formation depth of ore-bearing granite bodies. Background technique [0002] Due to the rapid development of my country's economy and society, the consumption of various solid mineral resources is increasing day by day. Therefore, in recent years, the exploration of solid minerals has moved from the shallow first prospecting space to the deep second prospecting space. Taking Jiaodong Gold Mine as an example, in recent years, the exploration depth has been greatly expanded from the original shallower than 1,000 meters to shallower than 2,000 meters, and some parts have even been drilled to 3,000-4,000 meters. With the substantial expansion of the exploration depth, the resource v...

[0003] In contrast, the exploration of uranium resources, especially the exploration of granite-type uranium deposits in southern my country, is still shallower than 1,000 meters at present, and even the drilling evaluation depth of most exploration areas is only about 700-800 meters. has not increased significantly since

An important factor restricting the long-term stagnation of the exploration depth of granite-type uranium deposits is the lack of understanding of the deep prospecting potential of this type of uranium deposits, that is, the failure to scientifically evaluate the vertical crustal extent of mineralization of granite-type uranium deposits and its post-mineralization. degree of denudation
