Method for quantitatively estimating deep prospecting space of granite type uranium ore deposit

Abstract

The invention belongs to the field of solid mineral exploration and particularly discloses a method for quantitatively estimating a deep prospecting space of a granite type uranium ore deposit. The method comprises the following steps: step 1, performing metallogenic depth estimation of the uranium ore deposit; step 2, performing fission track analysis on zircon and apatite; step 3, estimating therange of the deep prospecting space of the uranium ore deposit in granite according to zircon and apatite thermal evolution histories obtained in step 2 and the metallogenic depth of the uranium oredeposit obtained in step 1. The method disclosed by the invention can quantitatively estimate the deep prospecting space of the granite type uranium ore deposit and promotes fast breakthrough of deepuranium resources of the granite type uranium ore deposit.

Description

technical field [0001] The invention belongs to the field of solid mineral exploration, and specifically relates to a method for quantitatively estimating the deep ore prospecting space of a granite-type uranium deposit based on the research on fluid inclusions of a granite-type hydrothermal uranium deposit and the thermochronology research on fission tracks of zircon and apatite. 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 th...

[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.
