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 particularly relates to a uranium molybdenum deposit target area delineation method, which comprises the following steps of: 1, carrying out regional mineral survey, and identifying main ore control factors; 2, carrying out uranium-molybdenum occurrence relationship research, and determining a uranium-molybdenum ore body space distribution relationship; 3, performing radioactivity measurement to define deep uranium mineralization information; 4, performing electrical measurement to define deep molybdenum mineralization information; 5, carrying out audio magnetotelluric AMT profile measurement, and exploring deep mine control information; and 6, carrying out comprehensive analysis to delineate the uranium molybdenum deposit target area. By means of the method, the uranium molybdenum deposit target area can be effectively and accurately delineated, simultaneous realization and advancing of finding uranium with uranium and finding uranium with molybdenum are achieved, and a new technical direction is provided for uranium-molybdenum co-associated uranium resource exploration.

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...
