Volcanic rock type uranium polymetallic ore deep ore body detection method

Abstract

The invention belongs to the field of uranium ore geological exploration, and particularly relates to a volcanic rock type uranium polymetallic ore deep ore body detection method, which comprises thefollowing steps: carrying out ore deposit geological investigation, finding out ore control factors and an ore body distribution rule, and researching and judging the development potential of a deep ore body; carrying out deep geophysical measurement to obtain deep volcano mechanism and fault system information, and delineating a deep ore control structure part; carrying out deep radon gas area measurement to obtain deep uranium mineralization information, and judging whether uranium mineralization exists in the deep part; carrying out component element geochemical measurement to obtain deep polymetallic mineralization information, and determining sampling granularity and sampling depth; and carrying out deep ore body prediction and drilling to verify implementation resources. According tothe method, the multi-element deep geophysical detection means, the multi-element deep geochemical detection means and the geological means are combined in order, effective detection of the uranium ore body of the volcanic rock type uranium polymetallic deposit at the depth of 1000 m is achieved, an exploration method system is enriched, the exploration success probability is increased, and the exploration cost is reduced.

Description

technical field [0001] The invention belongs to the field of uranium ore geological prospecting, in particular to a deep ore body detection method of volcanic rock type uranium polymetallic ore. Background technique [0002] With the gradual increase in the identification and mining of uranium resources in the first prospecting space, it has become a prospecting trend in the new era to seek resources in the second space. The average mining depth of gold and copper deposits in the United States and Canada has reached 2,000 meters, and the mining depth of the Sealand gold mine in South Africa has reached 5,000 meters. The China Geological Survey also called for a full-scale entry into the second prospecting space in 2013. [0003] Volcanic rock type uranium deposits / uranium polymetallic deposits are important types of uranium deposits, which used to be the most important type of uranium resource supply in my country. Chinese uranium geologists have established a series of sur...
