With the steady and rapid economic growth in our country, non-ferrous metals are widely used in various industries and the state has increased investment in the exploration of non-ferrous resources. 1: 50000 geophysical survey as the main purpose of geological prospecting preliminary survey is in the area of geochemical exploration has been enlisted all kinds of provincial, regional or local geochemical anomalies within the range, and based on geochemical exploration, geophysical and geochemical data In the prospecting area, the target area for prospecting (ore deposit, ore body or other geological body) is further narrowed down, and geochemical characteristics related to ore prospecting and favorable prospecting are identified.
