Embodiment

[0067] The present invention will be further described in detail below by taking the expansion of peripheral resources of the Zhangmajing uranium-molybdenum deposit in the Guyuan area of ​​the northern margin of the North China continental block as an example.

[0068] Step (1): Carry out regional mineral survey and identify main ore-controlling factors.

[0069] On the basis of systematically collecting and studying the 1:50000 and 1:10000 regional geological maps of the Zhangmajing area, the 1:2000 geological map of the Zhangmajing uranium-molybdenum metal deposit, the detailed investigation report, and the profiles of each exploration line, etc., the known A typical ore deposit investigation has been carried out on the ore deposit. The investigation content includes ore-forming geological processes, ore-forming tectonic systems, ore-forming geological features, and ore-prospecting signs. The main purpose of the survey is to discover or expand mineralization clues, mainly in...

Abstract

The invention belongs to the technical field of uranium-polymetallic ore geological exploration, and specifically relates to a method for delineating a target area of ​​a uranium-molybdenum deposit, including step 1: carrying out regional mineral surveys and identifying main ore-controlling factors; step 2: conducting research on the occurrence relationship of uranium and molybdenum, Determine the spatial distribution relationship of uranium-molybdenum ore bodies; Step 3: Carry out radioactive measurement to clarify the information of deep uranium mineralization; Step 4: Carry out electrical measurement to clarify the information of deep molybdenum mineralization; Step 5: Carry out audio magnetotelluric AMT profile measurement to explore Deep ore control information; Step 6: Comprehensive analysis to delineate the target area of ​​uranium-molybdenum ore deposit. The present invention can effectively and accurately delineate the target area of ​​uranium-molybdenum ore deposit, and realize "finding uranium with uranium" and "finding uranium with molybdenum" simultaneously. It provides a new technology direction for the exploration of uranium-molybdenum co-associated uranium resources.

Description

technical field [0001] The invention belongs to the technical field of uranium-polymetallic ore geological prospecting, and in particular relates to a method for delineating target areas of uranium-molybdenum deposits. Background technique [0002] Using the radioactive characteristics of uranium element for ore prospecting is a significant feature of the exploration activities of uranium deposits and uranium polymetallic deposits, such as: surface gamma total measurement, ground multi-channel energy spectrum measurement, radon gas measurement, thermoluminescence, 210 Po, etc., is a common method for the exploration of uranium deposits and uranium-polymetallic deposits. [0003] Volcanic rock-type uranium deposits are an important type of uranium deposits in my country and one of the four major types of uranium deposits in my country. The co-association of U with Mo, Be, Cu and other polymetallic elements is a major feature of volcanic rock-type uranium deposits. The Guyuan...
