Description

technical field [0001] The invention relates to the field of geophysical exploration, in particular to a method for delineating favorable ore-forming sections of uranium-polymetallic ore. Background technique [0002] Uranium-polymetallic ore is a type of deposit that is dominated by uranium, and common non-ferrous metal minerals such as copper, iron, molybdenum, lead, and zinc are symbiotic. Its mineral composition is mainly characterized by the existence of uranium in the form of oxides, and the existence of other non-ferrous metal elements in the form of sulfides. With the upwelling of deep hydrothermal fluids and the exchange and transformation of surrounding rocks, local enrichment of minerals occurs, and finally composite uranium-polymetallic deposits are formed. [0003] To carry out exploration work for this type of uranium-polymetallic deposits, the preliminary work is mostly based on surface geophysical surveys. Geophysical measurement refers to obtaining the dis...
