Embodiment Construction

[0024] A method for quickly searching for hard-rock uranium ore-controlling structures based on multi-source data fusion of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] A method for quickly searching for ore-controlling structures of hard rock type uranium deposits based on multi-source data fusion of the present invention is operated using ENVI software in this embodiment. The first choice is to select the appropriate aeromagnetic, aerial release and high-resolution remote sensing data, and then perform operations such as coordinate system conversion, resampling, and cropping to unify the coordinate system, spatial resolution, and map size; The aeromagnetic, aerial and high-resolution remote sensing data are respectively loaded in the RGB fusion channel to obtain a fused color image; through the abnormal shape and position of the high-brightness aeromagnetic and aerial radio, combined with the s...

Abstract

The invention belongs to the technical field of remote sensing information science technologies and geophysical exploration technologies and particularly relates to a multi-source data fusion-based fast searching method for a hard rock-type uranium ore-controlling structure. The method provided by the invention comprises the following steps of aeromagnetic and aeroradiometric data processing, high-resolution remote sensing data preprocessing, data fusion and uranium ore-controlling structure confirming. Multiple uranium exploration-related data, such as aeromagnetic data, aeroradiometric dataand high-resolution remote sensing data are fused, uranium-related information is comprehensively superposed in space and the hard rock-type uranium ore-controlling structure is identified, so that the method provided by the invention has the characteristics of being fast and effective.

Description

technical field [0001] The invention belongs to the fields of remote sensing information science and technology and uranium ore geology, and in particular relates to a method for quickly searching for ore-controlling structures of hard rock type uranium deposits based on multi-source data fusion. Background technique [0002] The ore-controlling structure is an important factor in the formation of ore deposits. The determination of uranium ore-controlling elements is an important link in uranium ore exploration. How to accurately determine the ore-controlling structure is of great significance to uranium ore exploration. [0003] The formation of hard rock type uranium deposits, especially alkali metasomatized rock type uranium deposits, is accompanied by magmatic activity, which will inevitably cause changes in geomagnetism. Of course, the radioactive characteristics of uranium deposits determine that uranium deposits, especially shallow surface uranium deposits, have parti...
