Geochemical environment

Interpretation: Due to uneven distribution of geochemical elements in different regions, its geochemical environment composition and environmental structures are also different. Regions that are consistent with geochemical conditions are divided into the same geochemical environment zone, with the same geochemical environment zone having the same or similar terrain and natural geographic conditions, the same type of rock and soil properties, in the same hydrothermal conditions, and distributed The same biological community.
