Problems solved by technology
[0003] Due to the coverage of the Quaternary system on the surface, it is difficult to find volcanic institutions through surface geological observation, and it is impossible to determine the direction, shape and scale of deep volcanic channels, which makes the current deep hydrothermal uranium exploration lack of direction. The spatial distribution of volcanic channels is the key to finding deep volcanic-type uranium deposits

Embodiment 1
[0024] This embodiment provides a method for delineating a deep volcanic channel in a volcanic rock-type uranium deposit. Please refer to figure 1 , the method includes:
[0025] S1. Select a borehole in the study area, and select different types of volcanic rock samples from the borehole to measure density and resistivity, and obtain density variation range data and resistivity variation range data of different types of volcanic rocks.
[0026] Specifically, the selected drill hole should be located in the work area, and the depth of the drill hole needs to pass through the volcanic rock caprock to expose all the volcanic rock. The density measurement of rock samples of different lithologies was carried out by using a balance and a measuring cup, and the resistivity measurement was carried out by the SCIP rock electrical property measuring instrument. The number of samples of each lithology was not less than 30. The density and resistivity variation range of each lithology w...

The invention relates to a volcanic rock type uranium deposit deep volcanic channel delineation method, which comprises the following steps: firstly, carrying out drilling rock physical property measurement work in a research area, and determining the density and resistivity characteristics of volcanic rocks; then gravity measurement is carried out in the working area, and the Bouguer gravity anomaly of the working area is obtained; determining the density characteristic and the spatial distribution form of the volcano channel through three-dimensional density inversion; carrying out broadband magnetotelluric profile measurement to obtain deep resistivity characteristics, and delineating volcano channel resistivity characteristics and a spatial distribution form; and finally, delineating a deep volcano channel range by using the density characteristic and the spatial distribution form as well as the resistivity characteristic and the spatial distribution form. Through physical property test statistics and two geophysical combined detection methods of high-precision gravity and broadband magnetotelluric, the deep volcanic channel is rapidly delineated, important information can be provided for volcanic rock type uranium mine exploration, especially deep prospecting, unnecessary geological and drilling work is reduced, and the prospecting period is shortened.
Description
technical field [0001] The invention relates to the field of volcanic rock type uranium ore prospecting and deep geophysical exploration, in particular to a method for delineating a deep volcanic channel of a volcanic rock type uranium deposit. Background technique [0002] With the rapid development of my country's nuclear power industry, the demand for uranium resources will also increase in the future. Volcanic rock-type uranium deposits are one of the main types of ore prospecting in my country for many years. During decades of exploration, many deposits have been found and developed. It is found that known deposits and deposits are closely related to deep thermal activities, especially in volcanic areas. Mineralization is more likely to occur in the interior of the channel and in the structural fissures of the erupting volcanic rocks. [0003] Due to the cover of the Quaternary system on the surface, it is difficult to find volcanic institutions through surface geologic...
